1.1 Introduction

 

This paper is an attempt to document the approaches to organising improvisation that have been influential on my practice in the Oxford Improvisers, Spontaneous Arts Collective and educational work (mainly with Kate Comberti and the Oxford Philomusica). Some of what I document includes suggestions and solutions to problems of creating work that I and colleagues have come up with both for encouraging participation amongst non-improvisers and for maximising participation by a group of skilled improvisers; other aspects include established repertoire and approaches from jazz and contemporary music innovators in the field which we have adapted and used in combination or in new situations.  Often an approach that works well for beginners is equally valid for professional musicians - especially in the case of tried and trusted exponents like John Stevens[1] and Pauline Oliveros. [2]

 

This does not mean that I believe that improvisation always needs to be organised, channelled or controlled. What we have found with the Oxford Improvisers is that over time the group has enhanced its skills in communicating effectively and authentically without a predefined structure even in large numbers (10 - 12) despite the caveats of many that groups need to be small [3] A simple processional technique (where three people play together in turn with the players processing through the ensemble in turn) is often as successful in creating new work as any elaborate plan.

 

However, the imposition of structure can be liberating for some players and is definitely an advantage for those who lack confidence to improvise without some degree of encouragement. In addition the effort of breaking out of established patterns and vocabulary can occasionally be insurmountable even for the best improvising musicians where a predefined structure or approach can compel a change of practice.

 

Ideally the practice of free improvisation should continue (once established within a group) in parallel with the imposition of framing and structuring ideas.

 

I have attempted to categorise and document as many different approaches as possible outside of pure notation or totally 'free' improvisation. I have begun with conducted improvisation because that is an invaluable starting point for pulling a group together (it proved so for the Oxford Improvisers and I have found this in schools and community work).

 

1.2 Conducted Improvisation

1.2.1    History

 

Although specific groups have used the shorthand of established conducting symbols for many years (I have no doubt that the Baroque ensembles of Corelli or Vivaldi would have developed easy signs for much that is left empty in the surviving notation of their work), the establishment of a standard set of signs to enable a conductor to develop a complete work in collaboration with an ensemble is a recent event. More than anything it enables a democratisation of the creative process because anyone can take the role of conductor/facilitator of a group piece once they have learnt the vocabulary of signs. It is quite likely that this echoes the democratisation of sound mixing that has taken place through the proliferation of sound mixing technology (in PC's etc). In fact the conductor in this environment is often like the sound mixer in taking over a flow of musical ideas form performers and highlighting and enhancing some (and removing others); changing the parameters for performance and setting up different combinations of sounds.

 

The emergence of the idea of a creative partnership between conductor and performer into the art-music world really seems to date from the American experimental music tradition with the work of Earle Brown[4] in the 1950’s.  Similar developments had been and were happening in jazz and perhaps it is no surprise that Brown was the most directly and openly influenced by jazz of the New York School.

 

Starting with Brown and his colleagues in the New York School there have been various experiments at combining the creative input of players with a minimum of  structuring supplied by text scores, rules,  graphics, and even prescribed signals for a conductor. This took a more overtly political stance with the work of Cardew [5] in the sixties and seventies and in recent  years the work of Zorn[6] (with game pieces) and Butch Morris[7] has further developed the idea of a partnership of player, conductor/composer as opposed to the more traditional art music hierarchy (perhaps exemplified by the way Stockhausen felt his text pieces were an expression of his own rather than a collective will [8]).

 

The work of Butch Morris has been particularly significant because he has attempted to standardise an approach to using signs and symbols to conduct improvisation (often for large ensemble or orchestra). As he explains in the sleeve notes to ‘Dust to Dust’:

 

"Conduction" (conducted improvisation) is a means by which a conductor may compose, (re)

orchestrate, arrange, and sculpt both notated and non-notated music. Using a vocabulary of signs and

gestures, many within the general glossary of traditional conducting, the conductor may alter or initiate

rhythm, melody, and harmony; develop form and structure; and instantaneously change articulation,

phrasing, and meter. For example, indefinite repeats of a phrase or measure may now be at the

discretion of the new composer on the podium. In this way conducting becomes more than a method

for musical interpretation, but an actual part of the process of composition. Conduction is a viable

musical tool for the improvising ensemble.

 

 

The standardisation of the approach has paid off in the sense that numerous groups have been formed which use a set of symbols established by Butch Morris as a starting point for developing work.[9] The way the symbols work is that the direction (almost the mix) of a work is determined by the conductor who can decide who plays and for how long and various constraints in the style of playing. The choice of notes, rhythms and communication with other players is  mainly left to the individual performer within the framework the conductor sets up.

 

Pat Thomas, who learned the techniques through performing in Europe with Butch Morris, taught them to the Oxford Improvisers Orchestra in 2003 and as a result of the success of their use the Oxford Improvising Orchestra was started by the Oxford Improvisers and Oxford COMA. The conduction techniques were used as a starting point but quite soon many extensions were made including their use in combination with other art forms - such as dance. The use of 'conduction' as a baseline vocabulary from which a group can develop new work has been a feature of many of the performances of this group since 2003.

 

1.2.2        Advantages of Conduction

 

The development of new work through the use of conduction does enable any member of the ensemble to control the parameters of sound of the group as well as performing within it. This had a cohesive effect on the Oxford Improvisers as it enabled everyone to develop their skills in this area. Mutual learning and passing on of skills and ideas was established and for many, the ability to establish quickly parameters for a performance led to the trial and development of new work which could be refined in rehearsal and performance.

 

Some felt that the conduction approach lost the advantages of listening, communication and mutual support that an experienced group of improvisers can achieve through focussed and attentive playing together with no directional control. Most, however, agreed that the ability to shift the direction of a piece by changing groups of players, dynamics, registers and rhythms gave huge scope that consensus based playing tends to miss. For example, it is very difficult to get a specific sub group to enter a piece as a unit and give a strong timbral shift to previous playing unless this has been pre-arranged.  Or allow different players prominence at times when they would naturally shy from dominating the group sound.

These things can happen but with a fluctuating and open membership (as is the case with the Oxford Improvisers), they are unlikely.

 

Some particularly good examples of conducted improvisation as developed by the Oxford Improvising Orchestra are:

Pat Thomas conduction of the Armoury Section of the Accession Piece

Pat Thomas conduction of the Theremin Concerto

 

 

1.2.3        Extensions to conduction used by Oxford Improvising Orchestra

 

From the start of the Oxford Improvising Orchestra the opportunity was established for anyone in the group to develop new work using the symbols but extending them to incorporate other parameters (such as particular texts, graphics, melodic fragments, collaborations with other art forms etc).  To highlight the range of possibilities I will discuss a number of particularly useful approaches, pieces and signs that have been used in Oxford to enhance the standard conduction practice. (These are all based on an understanding of the core principles and signs documented in the Appendix A )

 

 

Multiple conductors and tagged conduction: The liberating effect of moving from performing to giving directional control can be enhanced by encouraging multiple simultaneous conductors. These conductors can be allocated part of the ensemble or compete with one another for the whole group. The parallel development of  different rhythms contrasting timbres can give an interest and complexity to a piece that a single conductor cannot achieve.  This can be further enhanced by  passing on the role of conductor amongst a group and seeing how the changes of personality affect a performance.

These techniques are demonstrated in the recording of Accession II (part 15 or Track 6 on the CD release. In the context of the piece this section worked as a summation of what had happened as everyone who had conducted so far in the work was eligible to participate (two conductors were agreed to start and each could pass on to one of the other nominated people at will). Hence, their techniques and styles could be revisited in this one place.

 

 

Use of texts:  I have attempted to create a specific atmosphere in a piece by the use of text. Using a singer (D'orowing) who would be conducted in as any other performer I gave her William Burrough's Book of Dreams and asked her when brought in to choose any passages at random and interpret at will.

The resonant and other wordly images of this text did create a very particular atmosphere to the piece and fashioned how I brought in musical responses from the performers. A similar attempt with Haiku was reasonably successful but the less predictable Burrough's text worked better because of its rapid transitions between the mundane and the fanciful.

 

The SPARC group is developing these ideas further with the use of text based pieces. Alan Buckley is currently developing a piece where a recording of a poem he has written is played on a tape to an artist who draws a response. Dancers interpret the response and they in turn are interpreted by improvising musicians. The whole process is observed by artists (in the audience) who create visual representations of it (which could be used for a further work).

 

 

 

 

Use of Melody:   Although to many improvisers the use of melody was seen as a step back to a previous musical language the wide range of interests of the improvising group in Oxford has led to a philosophy where traditional methods of structuring music through notation are accepted as part of the available resources, provided the notation is an aid to structuring the free expression of the players and not the entirity of a work. This seems to parallel the increased use of melody in other improvising groups such as the London Improvising Orchestra, where composer/performers such as Simon Fell[10] use some notational ideas in their compositions.

 

In order to explore the contrast between modal improvisation and the total harmonic freedom of the improvising orchestra I set up a piece where a specific signal  would mean use a prescribed melody of any part of that melody (played backwards or forwards at whatever speed desired). In contrast players  would have total harmonic freedom when not requested to use the melody. The melody I chose was the plainsong Pange Lingua which is in phrygian mode. The way I tended to structure performance was around a continual dialectic of performers exploring the melody and its ramifications within the mode as against those free of the harmonic constraint who would tend to destabilise and destroy the melody. The weight of the performance would shift between the two sides as performers were brought in one style or another.  I extended the techniques of using melody in contrast to free playing in the Accession Piece as follows:

 

A series of fragments of melodies was used by all performers. These fragments related to full melodies used throughout the piece (all accession state anthems or folk tunes). A performer could be asked to play a fragment at any time by a symbol (F) followed by the fragment number indicating the specific one to play at the next down beat.

Accession I (13): Four players were allocated folk tunes. Each of these players was linked to one of four dancers. They played only when the dancer moved. The dancers came in turn and left gaps between moves. Ultimately two dancers remained in motion and the entire improvising group (18) was split between the two conflicting melodies. Ultimately one dancer alone continued at which point all played the same tune (or improvised on it).

Accession II (17 – track 4 on the released CD): Eight players were allocated anthems. They begun their anthems as conducted in  The remaining ensemble created a wall of noise that  began softly and gradually took over all players - including the anthem players.

Accession II (16 – track 3 on the CD) A melody written around the lyric of the poem Springtime Behind the Slaughterhouse was played solo on alto clarinet. When played through two string players joined the clarinet player in an improvisation following from this melody.

Accession II (20 – track 7 on the CD) a melody based on the lyric of the poem On Parting was played on flute. A group of three players joined the flute player. Simultaneous to this each remaining  member of the ensemble played a very soft very high note (starting in turn as brought in by the conductor). Ultimately the improvising musicians joined the ensemble to indicate the end of the piece (which also marked the end of the whole work).

 

Sonic space,  subtlety and timbral exploration

 

In large group improvisation there is always a danger of overplaying. Although this often lessens as a group coheres it can be lessened by specific structuring techniques. The same also applies to volume and the ability to hear subtle sounds and extensions of instrumental technique.

 

These problems generally do not apply in small groups - especially in duos and trios - where the players will more easily adjust to hear the quietest sounds. Also the concern with subtle effects and simplicity is a particular phenomenon of our times and reflects the increasing importance of the legacy of Feldman [11], the French Spectral Composers [12]. The New London Silence Movement reflects a radical improvisational position with regard to these issues. An interesting web discussion of their label is at http://www.splitrec.com/index.php?go=subreductionismandth

 

The processional is one approach to allowing space for performers. Other approaches listed elsewhere (dance led improvisation which controls who plays or conduction which can isolate individual performers or small groups of performers) can also help indirectly.

 

Dominic Lash, possibly influenced by his connection with London performers, has been keen to explore space and quiet. His piece Van Hagen's Voicebox explores setting up a range of timbral effects for instruments (originally voices) which enforce the use of extended technique. Further pieces have explored the interplay of quiet unvoiced sounds.

 

I set up the section Lake of Tears in the Accession Piece to explore quiet sounds whilst using all the parameters of conducted improvisation outside of volume. The section was controlled by the parameter that no-one could play above the volume of  a singing bowl - which had to be audible for the duration of this conducted improvisation. I asked Bruno Guastalla to conduct this piece because of his expressed interest in extending parameters to playing by conceptual ideas. His original approach to this conduction was to add in symbols to indicate playing 'cold' or 'hot'. The abstruseness of this concept did produce some interesting results but in fact the concept of the Lake of Tears proved sufficient to influence the players - along with the rigid control of volume throughout.

 

Miles Doubleday explored the idea of enforcing space by structuring a piece so that all the players thought of a number and  a pulse. They would then count to that number repeatedly using the pulse they had thought of. Every second time they counted to the number they would play their instrument.

 

Miscellaneous  pieces:

 

Rapid Fire Duos: Miles Doubleday developed this piece on the principle of exploring the effect that a series of  duos (brought in and terminated by the conductor) can provide sufficient variety and interest to constitute a piece in its own right. So, given this pre-condition the conductor simply points at two people and with the down beat they start playing together and play until they are signalled to stop. Other duos can play (as separate units) in parallel with them at the discretion of the conductor.

 

 

1.3 Use of other musicological principles (some of these relate to small group improvisational structuring as much as to extending conducted improvisation)

 

1.3.1        Use of series

 

The use of a series to create a particular style of work has been attempted in a number of pieces. Although qualitatively this may be seen as similar to using a specific mode or scale it seems to create a different effect by the fact that it does not so easily fall into the production of melody or riff. It tends to encourage the use of sound colours - reminiscent of the total serialist approach.  The easiest way of using a series is to use a conventional chart and an improvising group (ideally not too large) can use the chart in any direction (Appendix C contains some example charts I have used).

 

Much depends on the style of the tone row developed. An interesting experiment is to take a series by Webern or Berg and see whether the improvisation bears any stylistic resemblance to the work of the original composer.  All the considerations that apply to deriving a series for a formal composition apply to deriving a series to use for improvisation: the choice of intervals; repeating (or retrograde) structures in the series etc. 

 

The 'pointillist' nature of the outcome of a series based improvisation is often enhanced by the lack of direction and resolution that the encouragement to use a non-diatonic approach, with no other guiding principle, can have.  This can be a useful non-directional aim in itself but it can be obviated by further structuring techniques. Bruno Guastalla in the use of a series for dance collaboration prescribed that the three performers used a chart at will, but when they reached a central block of four squares in the series chart that they stayed on that repeating et of notes. This narrowing of the parameters gave a clear direction to the piece. 

 

Chris Brown in his piece the Remnants of Resonance (for three performers) used a series to structure sections of an extended work which explored contrasts between free improvisation, the timbral contrasts range of each combination of the trio (solo, duo or trio) and the expression of the series in different styles.

 

I attempted a similar structuring in the piece Rented Space (Appendix B) which I developed with Barry Reeves in 2003. This used five performers each in a stall in a disused dairy. The performers all had the option of using a series (or not) in their improvisation. The piece was in five sections each one preceded by one performer reciting part of a dream he had had and playing a version of the series on the English Concertina. Each improvised section had a different parameter or structuring mechanism (fast or slow; different numbers of  performers; antiphonal responses; different order of entry or exit of the performance).

 

 

1.3.2    Use of pitch class set

 

The use of a motif  and its repetition and transposition within a group is often a key element in the communication strategies of a group of improvisers ( as exemplified by  the Spontaneous Music Ensemble - Karyobin as a key example [13]).  In a sense this was always an element of art-music, especially in fugue and the inventions of Bach. Here however, the interest is often enhanced by the conflict between tonality and the exploration of motif. In the Second Viennese School pre-serialist works of the early twentieth century an increasing interest in motific and canonic structuring becomes more important as tonality is discarded. It was not until the 1960's that the idea of using atonal exploration in improvisation became a formal aspect of performance within the new genre of free improvisation. 

 

Formalisation of a pitch class set as the inherent structuring device of a piece is perhaps a limiting device that enforces this kind of interaction. However, it defines and limits the parameters for extension in that expansion and contraction of a set of notes is ruled out if players are to strictly adhere to this approach.   As with the series, the construction of a set determines a great deal of the initial style of a piece. A pitch class set that incorporates octatonic relationships will often create a resonance of atonal expressionist works (as  a series in this style will also).

 

 

1.4  Text and Graphic Scores

 

1.4.1  Introduction

 

The development of text and graphic scores seems to be prevalent from the 1950's - again with the work of the Cage circle (Cage, Feldman, Wolff and Brown). Text scores can create a broad overview of the way a piece should develop totally removed from the actions that will be used to achieve the score, or impose strict limitations on what performers can do.

Graphic scores can be equally generic or specific.

 

I will try and categorise approaches within each genre.

 

1.4.1        Text Scores

 

Listening and communicative exercises.

 

The work of John Stevens (co-founder of SME) in the UK and Pauline Oliveiros in America seems to exemplify an approach around the development of listening and communication as the key skills in improvisation. The pieces that they have developed can be treated  as exercises to develop skills or concert pieces in their own right (provided they are played with conviction). They tend to keep instructions simple and clear and demand a level of concentration on performing a simple task to the best of your ability (whatever your previous musical training). Quite often they involve the development of musical skills of listening (Oliveiros refers to her whole approach as Deep Listening) and  development of alternative techniques through a communicative atmosphere. The scribbling piece by John Stevens demands that players 'scribble' on their instruments ( i.e. play without conscious planning ) while they listen to two other players. They gradually start listening to their own sounds after they are comfortable with the sound world created by their companions.

 

We were fortunate in booking Maggie Nichols (who worked extensively with John Stevens)  for a workshop where the efficacy and relevance of his work was demonstrated. As a result the idea of using simple structures to organise sound has been further validated.

 

 

Complex instruction

 

The philosophy of Christian Wolff whose text pieces were explored by the Oxford Improvisers at a workshop run by Howard Skempton in 2004 was often to use the ambiguity of language to create variety and complexity in a piece. So, in Play (quoted in full in Nyman p 114), the language is confusing and convoluted and the specific requirements are not tied down. The effect this has on performance is twofold. An ensemble may adopt a group approach that is very different, either within the group or compared to others. The performers may feel uncertain and stressed in trying to find the correct interpretation (because there is not one to be had). This can create a different level of concentration, more akin to attempting to realise the impossible complexity of a Ferneyhough score or the physicality of a Lachenman work.

 

The fact that the complexity and ambiguity is usually in the process of sound creation rather than the desired end result marks these as experimental works different in scope to the more prescriptive approach of Oliveros or Stevens where there is often a clear sonic aim.

 

Esoteric Instruction

 

The text work of Stockhausen in Aus Den Sieben Tagen further refines the ambiguity of instruction and the physical displacement of performers by demanding that they relinquish food and sleep or that they play in the manner of the Spirit of the Universe. But here the aim is confused because Stockhausen feels that he owns the work (in the traditional hierarchical mode of Western composition) whereas there is a democratising element in much of the work Wolff, Stevens and Oliveiros. This is born out by Stockhausen's possibly tongue in cheek comments about how the performers will know they are playing a vibration in the rhythm of the universe [14].

 

How these approaches have affected the Oxford Improvisers

 

Although Stockhausen's work has not been directly influential, the idea that an abstract state of mind or physical state can be used to colour a interpretation is one that has been championed within the group by Bruno Guastalla and Helen Edwards whose background in Butoh (a contemporary Japanese improvised dance movement) has probably encouraged this approach. Hence the unpopular suggestion by Helen that players swap instruments (only playing those that they are not familiar with) and much of the work that has been developed in the SPARC group (see multimedia work development below).

Bruno has often combined the use of physicality in playing with an interest in generating different colours and timbres of sound (this may reflect a particular cultural disposition as he is French).

His instructions can be deliberately abstruse as in the idea of rapid shifts between moods  (developed first for the Butoh Dance Group) or the imposition of the ideas of playing 'hot' or 'cold' within a conduction (an idea he trialled in Accession for the Lake of Tears which he conducted). The difficulty of interpreting this last command produces unpredictability (and an obvious player insecurity) much as the commands of Stockhausen can or even the convoluted nature of Wolff's texts.

 

1.4.2       Graphic Scores

 

Pure abstraction

 

Because of their proximity to improvised music the Improvisers have concentrated on the more abstracted graphic scores  in performance:

Brown's December 1952  was performed at the  Barbican in January 2001 by the Improvising Orchestra (I conducted) and in Oxford. It was performed by Hadaly (improvising trio in which I perform) accompanied by Ana Barbour (dancer) who interpreted the score on an equal basis with the musicians. What was interesting in these performances is that both adapted the performance of the piece to represent current ideas of the performing groups.  The Oxford Improvising Orchestra performance was conducted ( I wore the score printed on a T Shirt so all the players could easily see it and my instructions) and the conduction structured the performance in a way that reflected the normal operation of the group. Hadaly worked with a dancer who interpreted the score on the same terms and as an equal participant with the musicians.

 

I organised a performance of Cardew's  Treatise in its entirety in December 2004. This involved some dance as well as combinations of different ensembles (some conducted ) performing different selections of pages. Prior to this performance I organised a workshop by John Tilbury on how to interpret the piece (John, as a member of AMM has performed this piece for thirty years).

 

My personal experience of both these pieces was of how intense the process of interpretation has to be.

To some extent we pre-planned how we would interpret the pages of Treatise we were allocated ( I allocated them mainly by chance) and were then forced to focus on these interpretations whilst trying to react meaningfully with other musicians in their interpretations.  The constant dialectic between these two aspects set up a tension in the playing that was greater than in normal ensemble playing, whether improvised or through traditional notation. Cardew's aim in producing Treatise is expressed in his 'Towards and ethic of Improvisation' (an accompanying document to the Treatise score) where he explains that he is looking for people who have a musicality, but not one corrupted by the expectations of conventional musical training. For these people the open ended nature of the score will be a stimulus to invent rather than simply relating the 'musical memories they have already acquired to the notation in front of them' ( p xix).

 

This pressure in performance is similar to what I experienced in playing Wolff's for One Two or Three Players. The notation here is process oriented and Nyman (p 69) omments on how this can give a sense of urgency in the performers belied by the calm and restrained nature of the music produced. I suspect that this pressure of interpretation in ways that are so different from our normal cultural conditioning (either notation of desired end result or framework for communication) is what causes this end result in both graphic scores and in the process orientation of Wolff's.

 

Derivation from musicality

 

Although Treatise contains staff lines on all its 193 pages, the other symbols used are often deliberately non-musical and force an alternative method of interpretation. This fits with Cardew’s aim quoted above of moving away from traditional music making and finding musicians who were open to new methods of expression and able to interpret visuals as a means to this.

 

In contrast, much of the work of Busotti tends to start from a known musicality which is deconstructed accordingly. The same could also be said of Cage – especially in the Piano Concert.

 

Busotti [15]

 

Cage (Piano Concert)

 

Mythological reference

 

Logothetis tends to combine mythological themes (from his native Greece) with comprehensible graphics relating to the named myths.

 

The piece Styx is a picture of the meandering Underworld River along which the players are expected to slowly progress in interpretation. The similarity to the progress of a stave makes this a very accessible piece for beginners in improvisation who can choose how far to attempt to address the oppressive mythological reference or else  simply interpret the linear unfolding of symbols to determine their performance.

 

I have found the work Styx by Logothetis particularly useful in workshops for beginners in improvisation.

 

Minimalism

 

Tenney's   On Never Having Written a Note for Percussion  can be treated as an exercise in developing listening and co-ordination much as the pieces of Oliveiros or Stevens. In a sense it is similar to the kind of improvising exercise that says get as much variety as you can out of a climactic crescendo and decrescendo on one note.

 

 

 

1.5      Game pieces and alternative structuring

 

Although we  have not directly explored the specific pieces of Zorn structured around games and game rules, the imposition of external and non-musical rules and ideas has been very influential in the development of work for the Improvisers because of the influence of the Butoh Dance Theatre, multi media pieces and of the interests of particular members of the group.

 

Antiphonal experiments.

 

The idea of groups (or individuals) playing against each other can open up a sound world that effectively uses performance space as well as unpredictable results ( if groups have rules for interrupting one another). A simple technique which we tried was to set up two groups opposite one another. One group starts playing and continues until any individual from the other group interrupts, at which point that group takes over until they are interrupted. This approach can be entertaining in the short term but the limitations of the game prevent it going anywhere. A refinement that I tried was to start with one person opposite a group. The group plays until interrupted by the single player (who then solos). The last person from the group to stop playing when interrupted has to join the solo player. The group remaining interrupt at will. But again when they are interrupted by either of the two players opposite    the last player in the group to stop playing joins the duo. This process continues until everyone has moved across the room .

 

Obviously there is a strong 'play' element in a piece like this but the simple structuring can be useful in creating sonic variety and in cohering the group. It is still simple enough to allow the performers to concentrate on their methods of expression although the result will be very different to a free improvisation.

 

Satie Instructions

 

The book a Mammal's Notebook by Satie contains a series of eccentric and esoteric performance instructions. These can be used in a conducted improvisation to create either a more tense or ludicrous improvisation (depending on the attitude of the group). I have used the instructions in a number of contexts:

In a conducted improvisation where the  conductor has the option of giving a performance instruction to a  player (or a group of players).

In a free improvisation where any player was free to get up and find an instruction and read it out. The group would then have to follow it.

In a dance led piece where some of the instructions would be randomly distributed to individual performers during the performance.

 

 

 

Processional and variants

 

The standard processional of a set number of people taking it in turn to play at any one time from a larger group is a well used improvising technique for a large group. Where a  procession is of three consecutive players, the procession moves through the group by one player stopping and the player three along from the player immediately starting to perform. This continues with each player dropping out and being replaced in turn until the performance has processed around the entire group (which has to be sat in a circle). Some alternatives that we have found useful are:

 

A crescent shaped procession is begun by four players, the two on each end of the crescent. The procession then move inward from both sides simultaneously. When the two innermost players are engaged (i.e. when the two strands have started to cross ) players can join in at will (moving out consecutively from the centre) until everyone in the ensemble is playing. The idea of this structure is to give an antiphonal sound at the beginning but also to vary the thickness of the sound (it will go down to two players in the middle, then expand to incorporate everyone).

 

Two processions are instigated but each procession is of one player at a time. However, one procession is very short (i.e. usually one note or sound  before moving on) and the other is longer  The idea of this is to allow solo expression to be supported by a pointillistic response by the remainder of the ensemble.

Rather than processing one or more musicians start a piece and can choose 0 or more players to take over playing when they have finished. This can create rapid shifts between 1 or 2 performers and most of  the group. The piece finishes when the last player ceases without passing on to anyone to continue.

 

Sonic space,  subtlety and timbral exploration

 

See page 6 above.

 

Spatial pieces

 

Punishing Schedule by Jill Elliott is a simple but very effective piece which enables structuring through the movement of one person. The score for this piece is included in Appendix B. The piece is structured around a predictable but variable element. The progression of a person around a room who is the stimulus for different people to play when he/she comes into vision. He/she progresses 16 x and each the performers who see him have an increasing number of musical events to perform (reaching an impossible number to achieve by the end).

 

 

1.6.      Collaborative structuring between different art forms

 

1.6.1    Introduction

 

The use of alternative art forms to structure and influence work has always been key to the experimental music tradition. The Cage circle were particularly influenced by visual artists [16] and Cage developed many of his ideas if collaboration with Cunningham (dance) and Rauschenberg (visual art). The Scratch Orchestra also had a strong influence from other art forms - perhaps because so many were former art students[17] and because Cardew was wary of the effect of musical training.  I would suggest that the influence of extra musical ideas has generally been the stimulus for all developments in music in the modern era[18]

 

1.6.2        Dance

 

At the formation of the Oxford Improvising Orchestra links were built with the dance group Café Reason Dance Theatre through the presence of Bruno Guastalla and Ana Barbour. These links were built on by a series of collaborative ventures which included performances at the Abingdon Festival and at Harcourt Hill Theatre as well as a number of events organised by Helen Edwards (also a member of Café Reason). The approach of Butoh Theatre includes exploration of the potential of extended work around use of parts of the body, as well as the full potential range of expression of the body (rather than any prescibed and stylised set of movements). This has strong parallels with the ideas of extending the vocabulary of an instrument that is prevalent in freely improvised music. 

 

Butoh tends to avoid rigid narrative structuring ( again an interest in contemporary music and improvisation) and often looks to bring in resonance from the unconscious by establishing loose structures for extended exploration (once again this is similar in scope to much of the work of the Oxford Improvisers ).

 

From the outset of collaboration we found that many techniques developed for improvising musicians could be used with dancers, even to the extent of using dancers and musicians interchangeably within a performing group under the control of conduction or of a prescribed system of control (such as a processional).

 

In addition a dancer could be used as a controller for an improvising group where the moves of the dancer could be interpreted as physiographic conduction ( as opposed to symbolic).

 

Further to this point an interpretation of December 1952 by Hadaly (three musicians and one dancer) showed how interchangeable dancer and musician can be in the interpretation of an abstract graphic score.

 

The use of dance led (physiographic) conduction does pose some problems for a group. In traditional conduction the parameters of who plays when are controlled by the conductor and variety of texture is a key element in fashioning a piece. Where the performers are left to interpret a central dancer there can be too much continuous playing. In addition the musicians have to work at two levels simultaneously, in interpreting the dancer and at the same time listening to the sounds of their colleagues and communicating their ideas with them.  The tension of these conflicting demands can create some interesting work (it is after all a parallel to the conventional need to interpret a score and simultaneously communicate with an ensemble). However, the integration of  movement with sound can be organised around different groupings and allocations, the simplest of which is the use of the 'play like' by a conductor to tell a dancer to follow a musician or vice versa. Other techniques we have tried successfully are:

 

Dance led performance where the use of a particular object by the dancer indicates that particular  musician(s) should play. This was developed by Helen Edwards and I in a performance of a piece Meetings with Water where each of four performers would play only when an object assigned them was picked up by Helen (who was dancing).  Helen could interact with all four objects simultaneously if she chose - or none. So the parameters were open and the variety of expression would flow from a chance mechanism - Helen did not plan when she would interact with each object or how.

This technique was further used in the Accession Piece (Before the Entrance to the Garden) when a series of artefacts representing aspects of European Imperialism were used to control the 18 piece ensemble.  Each section of the ensemble (woodwind, keyboards, percussion, guitars, strings) was associated with an object but in each case a single member of the group was expected to interpret Helen's interaction with the defined object. The rest of the group would support that player's interpretation (this was to get round the problem of multiple interpretations by the same section of the same dance movements).

 

 

Performer pays a specific melody when an allocated dancer moves ( see description under use of melody above)

 

Use of processional technique.  The standard processional of a set number of people playing at any one time from a larger group is totally adaptable to a mixed group of dancers and musicians (as is most conduction provided the instructions to play, copy etc are applied to movement and not sound). In this instance the ordering of dancers and musicians can be significant as the norm would be to intersperse dancers and musicians to prevent pure music or dance at any one time.

 

Use of texts to develop performance. Two projects that have employed the use of texts to colour the method of interpretation of dance are a revisualisataion of Pierrot Lunaire in improvised dance and music and a collaboration around the emotive aspect of how we use and see our limbs.

 

For the Limbs Project – a collaboration between a film maker, Barry Reeves and Helen Edwards and myself – we also used a range of techniques in addition to textual exploration. These included the intuitive development of a visual response through film and the design by Helen of key positions to frame and develop the work – a kind of choreography of stasis. The textual exploration initially involved finding a range of poem texts that related to the subject. These were then used as a basis for improvisation and the creation of a collage of different resonances of the subject through vocal delivery. This combined effectively with the formalistically developed poses that Helen had engineered. A further development was to use message texts that the three of us sent round  over a period of a week and accumulated into a set of texts for improvisation. Details of this project are on a myspace page.

 

For the Pierrot exploration – a collaboration between Ana Barbour and myself (as well as a film maker Peter Green or some of the project) – we were consciously referencing the work of Schoenberg in Pierrot Lunaire as well as the full set of Pierrot poems that he based his work on. We found that key moments in the Pierrot poems could be isolated by using a few lines from each poem as a basis for exploration. These lines could be used to create melodies and incantations as well as the inspiration for particular movement and sonic exploration. The dance and music was combined around the interpretation of these fragments in a series of seven filmed explorations framed by pieces consciously composed to recontextualise Schoenberg’s music. This set of films is currently held on the Dispatx web site.

 

 

 

Issues of synchronisation

 

Much improvisation involving dance and music inevitably tends to generate an atmosphere of mutual support between the two practices once the artists are attuned to one another. The possibilities for developing new approaches as each art form influences the other directly are enormous, but , the possibility of juxtaposition and the interest that inappropriate pairing of sound and movement can give can be lost as well as the notion of the 'happy accident' that was so important to the Cage and Cunningham collaborations (nnn).

 

This issue came up in a recent collaboration between Bruno Guastalla, Pete McPhail and myself and the Café Reason Butoh Dance Theatre. In this work we attempted to avoid the straight support role by the following techniques:

·        one musician would face a dancer and work with them. The other two musicians  would face away and work together in contrast to the musician supporting the dancer, deliberately interrupting and subverting.

·         Although we were predominantly an improvising trio we attempted to link in a series scores to our performance so that there were prescribed sections of music. In parallel , some dance movements were choreographed to limit variety and the influence of the musicians on the movement of the dancers.

 

 

1.6.3   Film

 

Although structuring improvisation by film is part of the legacy of the silent cinema the use of narrative to structure improvisation (in the straightforward method of silent film) is not an area that we have attempted to explore due to its easy appropriation by melodrama  (the exception to this was a recent overtly melodramatic performance of a Victorian melodrama - half film half live action - using a Victorian toy theatre. This was initiated and organised by Miles Doubleday as part of a SPARC group concert). Our interest has been non-narrative film which enables the development of expression in parallel with the resonance of image, rather than directly supporting image. This has also enabled the involvement of dance in conjunction with the music, also developing a parallel path of expression.

 

 

Sumida Gawa

 

Barry Reeves developed a film, Sumida Gawa, which he based on ideas from the eponymous Noh Theatre piece which influenced Britten's Curlew River. The film highlighted key issues of the play, using images of the river around Abingdon extensively in this. Like much of Barry's film work the images were explored slowly and deliberately with no attempt to cut or move through a narrative sequence. 

 

At the point I took on organising the music to this film for a performance in 2004 at the Ark T Centre,  we had, in the Improvisers group, attempted a number of film accompaniments and had realised that with the subtlety of images present in films such as Barry's, that a simple small group improvisation using an extensive timbral range (to reflect the textural depth of the images chosen) was an effective accompaniment.  To this end I set up an ensemble of three (myself - violin and piano; Clair Aldington - recorders; Dominic Lash - bass) for the music (supplemented by Chris Brown - guitar at a later performance where there was no piano). Barry and I also felt that the slow pace of the film would allow a dancer to interpret the images projected - dancing in front of the screen and even creating shadows on the projected image where appropriate. Helen Edwards took on this role.

 

I structured the music around the elements of the most timbral change that could be achieved with the musicians available. For this I worked out those passages where a solo performance by each instrumentalists could support the images most effectively ( recorder solo to start; bass solo in the middle and violin solo to end). Between these solos combinations of duos and trios could enhance the images with more complex layering of sound.

 

 

 

Identity

 

As a reaction to a seminar day for all doctorate students on the issue of identity I started developing a collaborative piece with dance and film. I was interested in exploring the notion of identity as it appears in the recording of a performance and how that recorded identity can re-influence performers as they continue to express themselves in conjunction with the recording.

 

Helen Edwards and Barry Reeves each explored their own interests in the subject (as equal partners in the collaboration)  and we agreed to perform the piece over four hours at the OVADA Gallery in December 2005 using one other musician (Bruno Guastalla on cello and bandoneon), myself  (violin and keyboards), Helen (dance) and Barry (pre-recorded and live film).

 

The performance was structured around the continual revisiting of material developed in improvisation for the performance or during the performance. Barry had prepared films of Helen and I improvising which he edited and projected without sound at key points during the four hours. I attempted to remember what I had played when filmed and use that as a basis for much of the rest of my performance. At four times during the performance Barry filmed the performance against a backdrop of the previous film he had made of the performance. The filmed performance was projected and became part of a composite image on a large white wall that ultimately encompassed four visual layers.

 

Bruno recorded sections of the performance on mini disk and played this back for us to accompany at several points. Variety was further achieved by giving each performer working in solo. Duo, trio and quartet as well as interacting with previously created images and sounds.

 

 

1.6.4   Collaboration with visual arts

 

Project at Oxfordshire Health Authority School

 

Much of this area is covered in the discussion of the SPARC group but I did trial a number of ideas at the Oxfordshire Area Health Authority Schools earlier this year, as the composer in a team set up by Kate Comberti of the Oxford Philomusica  Orchestra.

 

The basis of the project was to explore links between the visual arts and music and as a starting point we looked at work by Rothko, Mondrian and Pollock and encouraged young people to use works as a basis for improvisational expression. From this point on we encouraged young people to create collective works (using conducted improvisation) to reflect reactions to visual arts works.

 

We then reversed the process by using recordings of the music produced as a stimulus to encouraging young people to spontaneously create a visual response (under the guidance of Mark Rowan-Hull an artist who specialises in this kind of work). The work was created on a floor space using a huge canvas (created by combining a number of sheets together).

 

Finally we took the large scale painting created by the group of participants and  encouraged them to find interesting shapes and ideas in it that could be expressed musically (via a graphic score). We created this graphic score by placing a huge plastic sheet over the painting and tracing the chosen shapes.

 

The graphic score was then used to create a final musical response by all the participating young people, taking it in turns to conduct and choosing when to use the score  and by whom it would be used.

 

I have detailed this example because it demonstrates how an ordinary group of teenagers can be drawn into  the process of creating work across different media and fully engaged in what is quite a challenging conceptual idea. The same techniques of feeding the process of one art form into the other have been developed extensively by the SPARC group.

 

 

1.6.5   The SPARC Group - collaboration across multiple art forms

 

 

In order to further develop the approaches of parallel development of work across different artistic media I was happy to help Helen Edwards in the formation of an open access group that would seek to develop work by improvisation across all available art forms. Practitioners were invited to join sessions  that incorporated poets, visual artists, musicians and dancers.

 

The SpontaneousARtsCollective has been meeting since January 2006 and has just succesfully completed  a week of developing and displaying work in the Old Dairy, Headington Hill Park at the end of July. This week culminated in five two hour performances by different combinations of the ?? artists (from different media) who are members of the SPARC group.

 

 

Development of work

 

As with the Improvisers Collective, all members of this open access group are encouraged to bring ideas for new pieces to the meetings. These are then trialled along with any ideas that come up spontaneously in the session ( provided there is time to do this). Helen runs each session and tries to facilitate as broad a range of material as is practical. What is interesting about much of the work that comes from these sessions is the efficacy of simple structuring techniques (much as with the Oxford Improvising Orchestra work) and the similarity in what is produced to the pieces developed by the Scratch Orchestra.[19]

 

Works Produced

 

I will try and categorise some of the styles of work produced and give examples of methods that seem to have worked well.  The group is still evolving techniques so it is likely that a far wider range of pieces will be produced in the near future.

 

Oxford Improvisers Legacy

 

Because so many on the group have been in the Oxford Improvisers a large number of techniques for organising the larger scale pieces have tended to come from the members of the group experienced in developing work for that group and from extending the conduction techniques that work so well for large musical improvisational groups.

 

Particularly interesting in this respect is a work devised by Miles Doubleday which allows for a rapid change of performers (see appendix nnn). Each performer (from any art form) holds a coin. The piece starts when the conductor bangs a gong and at this point everyone flicks their coin. Those that return 'Heads' perform at a second signal from the conductor. At the next gong sound the people not performing flick their coins to see who will perform next. At the next signal from the conductor those performing cease and those who were waiting to perform commence. The process continues in this way until the conductor indicates the end of the piece. The unpredictability of this approach (0 - n people can end up playing in any one section for as long as the conductor allows) provides interesting results and a total concentration from the performers. Miles had trialled this work with musicians alone at a previous Oxford Improvisers rehearsal.

 

 

Chains of instruction across different media

 

As part of the aim of the SPARC group was to explore the interplay of different art forms, it is not surprising that much of the work of the group has been around the establishment of structures whereby the effects of one art form can directly influence another.

 

Alan Buckley's piece exploring the effect of a poem (see above section nnn) demonstrates how one media can inform another.   This idea has been explored in a number of other works:

 

 

 

Use of specific performance space

 

 

Chris Stubbs  piece Radion is structured around the use of the bandstand in Headington Hill Park. A set of performers stand at the bandstand and slowly progress from it in straight lines that radiate out from it. At the same time musicians , who are distributed in an arc away from the bandstand, move towards it in straight lines, playing their instruments and converging on the bandstand. The two groups of performers should move at such a pace that they cross paths at the same time within an arc shape.

 

Janet Stansfeld developed an improvisatory piece that employs the use of musicians distributed in the stalls of the Dairy  in exactly the same way that Barry and I developed Rented Space four years ago. Janet was unaware of the previous piece and perhaps this demonstrates how an attitude to developing work that exploits the potential of a specific space tends to lead to similar pieces.

 

Jill Elliot developed a piece that explores the contrast between inside and outside of the Dairy in which performers gather ideas from outside the Dairy and bring them in the  Dairy to use in conjunction with other performers - on the model of gatherers bringing food into a shared domain.

 

Esoteric ideas

 

As part of the generation of ideas and creating of a collaborative atmosphere Helen Edwards has devised pieces which tend to enforce collaboration through the creation of undefined space or unusual activity that enforces the imposition of structuring by participants.

 

 

 

1.7       Conclusion

 

 

I have attempted to document a range of approaches to organising and structuring improvisation which have been of benefit to practising musicians (in the Oxford Improvisers and the SPARC group); within education; and to my personal practice as composer/performer.

 

To some extent I feel that this work supports the view of Bruno Nettl [20], that the terms 'improvisation' and 'composition' can be misleading and it is better to look at music in terms of the number of fixed elements and the number of free ones. Thus, whether a performer is constrained by specific notation, a set of text instructions, the conventions of a genre (such as blues or raga) or their own developed vocabulary is just part of a continuum that stretches from the work or a performer such as  Ian Pace interpreting the complex notation of Michael Finnissy to Evan Parker rejecting the notion of the score as a valid means of structuring a piece [21] and using the environment he is in to fashion the vocabulary he uses.

 

If we adopt Nettl's view then the choice for any composer or performer (as far as they are able to escape the conditioning of their society) is in how far to attempt to develop their own vocabulary in order to develop material spontaneously in performance, and how far to rely on pre-structuring (via score or any other means) in order to repeat aspects of a work that are interesting or original (at least at some point in time).

 

I would not subscribe to the view that notated composition is more 'original' or 'innovative' than music developed (or perhaps composed) in performance. This does depend on the skill and experience of performers and composers and it does depend on whether the implicit rules behind the generation of music in performance are more restrictive than those that apply to composers developing work prior to performance.  The elevated status of composers within Western art house music has enabled many to develop ideas and methods of expression that are far less predictable than those that tend to arise from a genre where the building blocks of a piece of music are predefined and unchangeable while the performers create the detail.  However where improvisation is undertaken by performers who are free to develop a work as they see fit [22], as with contemporary free improvisation, works may surprise and explore new territory just as effectively when composed in performance as when pre-composed.

 

That said, musicians do tend to rapidly coalesce to similar modes of expression as so much that we express is a vocabulary that we develop through hearing others and applying that to our own development. Most musical movements tend to stultify until replaced (often quite forcefully)  by an alternative method of expression. The high art motivation of total serialism is perhaps the most extreme example of a movement in which the main practitioners discovered, developed and then attempted to prescribe a more rigid set of rules for aspiring composers than has been imposed on many  artists by commercial, political or even religious factions in the past [23].

 

This can happen within an improvising group where a collective approach prescribes rules that may be valid for the time and current practitioners but can only become restrictive if applied unquestioningly for the future. [24]

 

The advantage of using a range of organising techniques, especially those influenced by other artistic media, is that it can broaden the vocabulary and approaches of a group of musicians in a way that the use of a single approach (just improvisation as dialogue within a group, or just notation ) cannot. In fact the frequently cited  inability of the classically trained to create any new work in performance  is testament to this.  The play element in many methods of structuring work via text instructions, graphics or collaboration with other art forms also opens up these traditional 'experimental' techniques to use in education where they can compensate to some extent for the damaging psychological effect that classical musical training can have on young people [25].

 

As someone who writes music I feel that I should be aware of as many different  possibilities for the structuring of performance as I can.  The integration of a range of performer options within one piece (from complete performer freedom to complete prescription) opens up the possibility of a far wider range of expression than any one approach. They can all be subsumed into the creation of a work provided the design of the work does not necessitate a completely closed and repeatable piece. If it does, this surely (by definition) places it in a very restricted and  specific genre category.  This may be a category that uses improvisation and this perhaps highlights how the ideas I have documented here are a resource for 'experimental musicians' following Cage's definition that experimental music is that in which we do not know the outcome. They are part of (or should be part of) the vocabulary of any composer who is not working within a specific and predetermined genre i.e. any art music composer. Which techniques are used must depend on the requirements of the piece - which can include educational, communitarian or commercial ideals as much as aesthetic ones. There must always be situations when the most appropriate choice is to give a group of musicians total freedom to develop work in performance and others where a totally prescribed score is more appropriate.

All worked on their instruments, on their own, to develop a highly personal language." So my first decision, which I think was the most important, was never to talk about language or sound at all. I left that completely up to the performers. What I was left with was structure.

What I came up with is a series of rules, like a trading system — one person plays, then the next person plays, then the next person plays — and event systems, where people independently perform events. Everybody can perform one event each, for example, but nobody can time it at the same time with anybody else. There might be a series of downbeats where at a downbeat a change will happen — if you're playing, maybe you must stop. If you're not playing, you may come in. That's just one example.

[11] Morton Feldman's compositional principles revolved around the creation of the purest form of 'absolute' music, and the need to define the relationship between sound and silence with the utmost precision. Webern was his starting-point, from which he elevated the pause to the same importance as all other gestures. Different kinds of notation were employed to create an exact equipoise between sound and silence, and to explore the interstices between painting and music; between time and space; between form and content.

 

[12] Spectral music began a quarter century ago in France considers tone colour (or timbre) as the main element of music - supplanting such traditional aspects as melody, counterpoint, and rhythm. Tone colour and harmony are understood to be essentially the same thing. Sonorities are based on the natural overtones and generalizations from such structures. Leading practitioners: Tristan Murail, Gerard Grisey, Jonathan Harvey

 

[13] Karyobin was released by SME (Spontaneous Music Ensemble) in 1968. It featured Kenny Wheeler, trumpet, flugelhorn; Evan Parker, soprano saxophone; Derek Bailey, electric guitar; Dave Holland, bass; John Stevens, drums.

[16] Brown was influenced by Calder's mobiles for many of his structuring ideas (Nyman p 51; Cage collaborated extensively at Black Mountain College (Nyman p 72) Feldman professed to be more interested in attending art galleries than new music concerts nnn

[17] The article at http://www.splitrec.com/index.php?go=subreductionismandth contains personal recollections of Scratch Orchestra membership from a participant.

[18] I believe it is quite likely that music as an art form can become too introspective and technically obsessed when academised  and that most innovation in music comes through the cross fertilisation of ideas from other disciplines or a rejection of developed practice, often for a simpler means of expression. This could be applied to the initiation of the Baroque (through an attempt to re-capture classical culture and a desire to capture the inflexions of human speech in the recicative); the acceptance of folk melody in Viennese Classical music in rejection of the complexity of the high Baroque; the influence of literature on the Romantic composers; and  the rejection of the legacy of total serialism by the minimalists (themselves perhaps reacting to the influence of a modern art movement).

[19] The Scratch Orchestra documented a range of ideas for pieces in 1971 in Scratch Music.  Many of these pieces are similar to the ideas coming out of the SPARC group.  This is perhaps not surprising because the Scratch Orchestra contained a wide range of artists as well as musicians. In addition, the anti-hierarchical ideology of both the Oxford Improvisers and the SPARC group is part of the legacy of the Scratch Orchestra as well as a British communitarian spirit (expressed also  by John Stevens and the legacy of his ideas as continued by Maggie Nichols).

[22] I would see this as a relatively recent phenomenon within Western music and cannot think of any other cultures where this has happened. Then again the freedom to compose music outside any but self-imposed boundaries is really only a phenomenon of the twentieth century occident.
