This got me thinking about a project which I thought of years ago, started, then abandoned. It was a music synthesizer/sequencer which you would program, by well, programming. I mean that the music would be controlled exclusively through a programming language. This would alter the creative process in several ways. Most music sequencers are graphical and allow you to lay out musical patterns in sequence. Writing a program is extremely non-linear, with classes, functions, and variables being defined in the code long before they are used. In this hypothetical sythesizer language. a composition might look something like this:
playSample("beat", start=0:32.1, end=0:33.5, beats=[1,3,9,11,15])
shiftPitch(start=A4, end=C4, duration=bars(8))
playSample("guitarRiff", start=1:15.3, end=2:09.0)
tempo 150 BPM
In the above example, the first play statement will be executed, then the third play statement (5 bars into the 8 bar intro), then the second solo will play again, probably before the first solo finishes. There are other interesting features in the pseudo-code above, but the fact that these sequences are played out of order was what I really want to highlight.
I've done live coding at several events over the years and I tend to have fun with it. It doesn't always go exactly as planned, but that is the whole idea. Live coding turns programming into a performance piece. I imagine there is a niche group of people who could really get into the live coding music scene.
