Algorithmic

Written in 1992 (at age 14), for an after-school music theory class, using an iterative algorithm (on paper). Came out far too long - I should have exercised artistic license over the math a bit more. I really like the last twenty seconds, though.

You were doing algorithmic composition at age 14? And a damn fine piece to boot, nicely done!

Yea, what TWR said. Did you do the "pshwt" sound with your voice (mouth?)

My algorithm for generation of the musics is O(n^2). Yours is clearl O(n).

Efficient!

This is neat.

sounds cool, personally I could do without the "pshwt." I'm interested in what you used to make this and what you mean by "on paper" ? Did you write out the notes based on an algorithm and then play them, or is it purely computer generated?

Surprisingly, it resembles traditional Chinese music.

My memory is pretty hazy, but I think I wrote out a few chords on paper, and then came up with a bunch of transform-over-time functions, and some functions that transformed the inputs to the transforms. I iterated over those functions by hand and wrote out the results on paper, then entered it into the synthesizer's sequencer.

The "pshwt" sound, as I recall, was originally some sort of very faint gong. It got mangled in the conversion between the Yamaha SY77 file and the General MIDI file somewhere - this existed as a .mid from 1992-1999, at which point I rendered it as a MP3.
