In this chapter I would like to focus on actual compositions that employ techniques like grammars, constraint programming, techniques from machine learning like Markov chains or artificial neural networks etc., and then discuss technical details in the light of such examples.

For example, there exist compositions where filter movements are controlled with rhythmic constraints, where multiphonics are composed with a constraint-based system, where rules control the resulting formats of an overall orchestral sound to make the orchestra “speak”… So, on the one hand, pieces that use such techniques in a somewhat unconventional way by going beyond the generation of mere note pitches and/or durations are interesting for me. On the other hand, of course also the generation of note pitches and/or durations can of course be characteristic, e.g., by further developing an underlying technique (e.g., by combining some knowledge-based technique with another technique), or simply the resulting music is convincing. You get the idea.

I don’t know, if simulated annealing process (Maxanneal by Iazzetta et al) I have the paper somewhere, but couldn’t find it now on my Macbook. It had c-code of the program, I grabbed it from ps-file. It works, and I’m just about to put it on github. I modified the code, and it writes scheme-file. Been testing it with Grace, and something it does.

Also I have code for jMusic using simulated annealing, but it uses different kind of qualification (much more elaborate). And, somewhere on my disks is a genetic algorithm with jMusic...

Do contact me, if you’re interested in these.
