| Something fascinating about seeing a 'score' for generative music
| written out as a sort of specification like that.
|
| There's enough detail there that you can take those instructions
| and reimplement your own version of it, and you'll end up with
| essentially the same 'piece of music', but certainly a different
| interpretation of it. Because while the score lays out some
| details precisely, it leaves other choices less clear. What does
| 'all inversions' really mean when enumerating chords? Does it
| include open, spread voicings? What durations should we choose
| from for our random waveforms? How short is 'short' when deciding
| to repeat? And of course, what wave synths should you use, and
| how should you modulate them?
|
| All those are similar to the decisions a traditional
| instrumentalist makes when interpreting a sheet music score for
| performance - here, a generative music coder can follow this
| 'score' and produce a program that represents their own
| interpretation of the piece.
|
| Coding it up in Sonic Pi (https://sonic-pi.net/) was a fun
| exercise, and I feel like I was able to produce something along
| the lines of what the composer intended. It carries the same kind
| of mood that the recording in the video has. But it's my own
| 'performance' of the work, if that makes sense (even if it's
| actually Sonic Pi 'performing' it at runtime...)
|
| All of which got me thinking about the relationship more
| generally between specification, and implementation. Considering
| different programmers' implementations of algorithms as
| individual 'performances' of scores from the overall design - and
| then thinking about developers building elements of a larger
| system architecture as individual performers working to deliver
| their part of the performance as part of a band or orchestra.
| Some groups, maybe they're directed by a conductor-architect;
| others maybe are improvisers, riffing off one another and
| occasionally stepping up to deliver a solo. And some are maybe
| solid session performers, showing up and delivering strong but
| unflashy performances to a producer's specification.
|
| So overall, a nice meditative coding exercise for a Sunday
| afternoon, and a shift in perspective. Thanks for sharing it.
