thinking aloud: listening and making generative music

Why just listen to generative music when you can easily make your own…1

It strikes me that because Generative music is likely different every time it is listened to, the act of listening to it can be accorded the role of creating that particular piece every time, therefore putting listening on a par with making, or even demoting listening as a role for the audience – maybe listening becomes “active,” listening as part of the generative process.

Generative music is the the most adaptable of “live” music – in that it’s always new, always different, no matter if it is a public or private situation, and it’s dependence on mechanical reproduction allows it the portability that “traditional” live music lacks. In terms of community experience, that particular version of the piece could be a shared experienced, in a live performance with an audience, but on a one to one basis it never has the potential to be communal, or shared – every launch of the piece occasions a new version, and unless it is hard coded as a static file cannot be transferred. But hard coding as a static file destroys the nature of the piece as generative.

One might ask what meaning it has if it is always different – where is the piece? This seems an inappropriate clinging onto outmoded forms, given the nature of generative systems, a paradigm for music (and indeed art in general) that may be difficult to maintain. If one must reduce it to such a thing one can look at it from two sides (maybe more). The meaning, the piece, is the method by which the piece is generated, the system, the order, the algorithm. Or, as I suggested above, the meaning is in the reception, but in a very fugitive sense. Static recordings can only be examples, maybe representing practical methods of revenue generation or dissemination, as in the production of documentation for ephemeral works by artists.

UPDATE: Coincidentally, Robin Peckham just posted a link to a piece by Nick Seaver, at the Comparative Media Studies department of MIT, where “he is studying indeterminacy and control in sound transmission, the role of ‘skill’ in aesthetic judgments, and the history of automatic musical instruments.” Nick posted a piece yesterday on his blog, noise for airports, about his research into the Player Piano. He makes an interesting point about “live” music, and its interpretation where the player piano is involved. This definitely relates to my notes above trying to define the “piece” where generative music is concerned:

“Live” music as we think of it today didn’t exist before audio recording—it was impossible for a sound to not be live. The player piano makes things a bit more complicated: is it still live if the notes are all punched on a roll in advance but “interpreted” by a live pianolist? Advertisements showing the ghostly hands of famous pianists on the keys suggested perfect fidelity: the parts of your piano would move exactly how they did when Rachmaninoff or Paderewski played. Would this recording, played on an actual piano, count as “live?” 2

Player Pianos were also an important instrument for the American composer Conlon Nancarrow, who wrote extremely complex pieces using punched paper rolls, pushing the machines to their limits and beyond the limits of the human ear. Sound and performance artist Michael Yuen tells me that:

Nancarrow had to specially alter his player pianos. they were fitted with vacuums to suck air out quicker. There are times when his music calls for 25 notes per sec. That’s a note every 40 msec. The ear can only hear a difference at best at 20msec. Without the turbo charged pianolas, the mechanism pulling the air couldn’t move the hammers and notes go missing. 3

I’d be interested to find out if these machines were popular in China, and if musical production of this sort has influenced the current generations of artists and musicians?

the “auto-” in creativity

Following on from the last post, I wanted to try and clarify my use of the prefix “auto-” to describe the types of sound that came up in the Subjam concert at UCCA. At the same time this will help put some meat on the bones of a project that I’m working on right now, a project whose subjects, and the arguments that I’m touching on in this post, cross over from the sonic arts to the visual.

By using “auto-” I was trying to suggest that the sounds had some kind of automatic, or non-human activity in its formation (although it would be a mistake to think that’s all I was interested in, but I’ll get to that later). In this case I mentioned “Auto-Generative” and “Auto-Destructive” sound, and although I used these terms in the title, I didn’t make it explicit in the text what they were referring to other than a vague idea of additive versus subtractive compositions (where I was tentatively linking the former to Zhang Jian and Wu Na, and the latter to William Basinski).

My use of the term Auto-Destructive is inspired by the work of Gustav Metzger (born US, but now stateless) and the Swiss artist Jean Tinguely. Metzger popularised the term in 1959 with his First manifesto of auto-destructive art,1 as a general principle and a way to describe his performance works using nylon and acid, a lethal combination which resulted in the destruction and disappearance of the material of the works. In a similar vein, Jean Tinguely is well known for his elaborate machines which progressively destroy and undo themselves. Both artists were working towards a dematerialisation of the artwork, a throwing into question of assumptions of the object-status of the artwork at that time. This (non- or negative-)thing that results was also one of the focii of Conceptual art, Metzger and TInguely in this case having quite an influence on their thinking. In their work Metzger and Tinguely presented the process of dematerialisation as being an end in itself, literally performing the critique of the object in front of the audience.

From “Auto-Destructive” the antithesis I set up was “Auto-Generative.” In this case the word “generative” comes from its use as a form of musical composition, usually associated with computer music. I have been thinking recently in this regard specifically of the composers Conlan Nancarrow (US) and Edgard Varèse (France, US), whose work involved investigation of systems which, although of course “man-made” in their inspiration or initiation, in execution relied on the working through of a set of rules by mechanical means.

For generative work human intervention can simply be a starting point, from which systems can work themselves out, the “human touch” can be removed entirely from the actual act of music/noise making. The extent to which the human needs to be involved in the act of music/noise making is a very divisive issue. For some the human touch is pre-eminent, for others a hands-off approach is the interesting means and I think it is this subject that can be usefully pursued, an which my project is working from.

It’s an important part of the project, too, that there should be no restriction for this to sonic investigations, it can equally be applied to visual and other forms. Metzger’s words, for example, apply across the board:

Auto-destructive art is art which contains within itself an agent which automatically leads to its destruction… Other forms of auto-destructive art involve manual manipulation. There are forms of auto-destructive art where the artist has a tight control over the nature and timing of the disintegrative process, and there are other forms where the artist’s control is slight.2

I have to admit, setting up these polarities of “auto-generative” and “auto-destructive” is a deliberate straw-man tactic, to create a discursive environment for the project. They serve as ideals around which to drawing out the arguments involved in various artists’ methods. As such, I doubt any artist would commit themselves to one or the other exclusively, certainly not over their whole oeuvre (or even within a single piece of work). However what the use of these terms does do is to set up a field of argument, around which the various participants can set up their camps, like a set of Venn diagrams of creativity, covering more or less of each of the meanings in their practice and theory.

It’s early days yet, but as the project progresses, more information will get posted here.

Auto-generative and auto-destructive music

This afternoon UCCA hosted a rather inspiring music event organised by Yan Jun’s Subjam label, including a collaboration between Wu Na 巫娜, on Guqin1, and Zhang Jian 张荐 (one-half of FM3) on a set of seven Buddha Machines2, after which American composer William Basinski 威廉•巴辛斯基 and film-maker James Elaine 詹姆斯•伊莱恩 took over for drones and tape loops, set against scenes of water surfaces intersected with branches forming shapes, in subtly shifting hues of gold.

Conceptually these two duos formed a nice counterpoint in terms of techniques and results. Wu Na and Zhang Jian represented for me an additive process, Zhang’s manipulation of the Buddha Machines producing waves of layered sound, it’s effects occurring through the cycle of sync and de-sync of the individual loops. Most of the time sitting back in his chair studying the hanging Machines and the sounds they were producing, every now and then he would rise up and put one to his ear, selecting a loop and adjusting the pitch to add to the mix, or make subtle changes to the existing setup. These changes initiated active systems between the set of Machines, gradually progressing through possible variations, intermittently adjusted by further tweaks to the dials. The Machines began at a low pitch and at first Wu Na’s playing added harsh interruptions to their flow, the absolute temporal fixity of the plucking of the giqan cutting through the smooth, endlessness of the loops. But as the Machines rose in volume the strings began to bleed into the systems, the highlights of bright picked sequences becoming aligned with the loops to eventually flow with them.

Willian Basinski, on the other hand, set up a spectacle with his loops with definite end-points, the consistent drone punctuated by ageing stretches of tape. Selecting a length of tape from his metal cookie box, inspecting it under the USB light attached to the computer which synthesised the drone, Basinski threads the selected length onto the spools of the obsolete deck which he has tracked down, wedging a spare beer bottle to take up the slack in the loop. The loop’s sound is mixed into the drone to create a series of vignettes of sound from each loop. I didn’t make the connection until afterwards, but I had already heard some of Basinski Disintegration Loops series before, a precursor to this method, recordings of his old archive loops gradually wearing out as the tape is dragged across the playhead – the sound of the destruction of the medium overlapping and eventually replacing the recorded content.

I tend to see William Basinski’s sounds as subtractive in their construction (destruction) of the music, or a process of negation, a stripping over time of the body, flaying the sounds into other forms. Zhang Jian and Wu Na seem to work in a process of addition, adding together to form the result. Loops which technically hold infinity in their structure, for Zhang and Wu form a continuum over which they can play, but for Basinski this continuum surrenders to its physical form’s frailties.

NOTCH: Halloween Sleeping Concert

NOTCH Halloween Sleeping Concert

Last night in the aircraft hanger-like space of The Orange in Sanlitun, the NOTCH Festival of Nordic + Chinese culture held their Halloween Sleeping Concert. Described as having “hypnotic audio-visuals and specially designed air bed by Swedish architecture group Testbed,” it’s not often an event would promote dosing off as part of its raison d’etre. Fortunately falling asleep was impossible as the Orange has loose partitions at the end that provide little to no heat retention, and last night Beijing experienced the first snows of winter, so the cloakroom was probably deserted as people generally kept their coats on throughout the event.

The sleeping premise of the concert was already somehow self-defeating, and in the event the cold prevented the complete absorption into the mood of the evening. Nevertheless it had its moments, when a particularly focused set of sounds and visuals attracted your attention, holding you for a moment. A good night.
