I have been playing with some ideas for a student project.
The basic idea is this. Western music is based on a 12-tone
equal-tempered scale where each note is the 12th root of 2 higher in
frequency than its predecessor
12 is nice number. It has divisors 6 4 3 2 which suspect leads to
mathematical harmonies.
But what if some other number had been used as a base? What would a
16-tone scale sound like? What would subset scales analogous to our
8-tone scales sound like? Would there be the analogs of arpeggios,
chords ...?
I thought it would be fun to create an applet that let people
experiment, like a miniature keyboard synthesiser with variable
tunings using the alpha keyboard or maybe even a traditional MIDI
keyboard.
You might even transcribe Bach into this scale in some way and see
what happens.
I have created synthetic sine wave sound before with the deprecated
sun.audio.AudioPlayer.
I wondered which of the following would be promising approaches to let
be produce more pleasing sound:
1. talking to a MIDI interface. It might lets me sample sounds but I
don't know if it would give me precise control of pitch.
2. converting sampled sounds to the desired pitch by mathematically
playing them too fast.
3. composing sound clips files mathematically and playing them.
4. use some already existing tools.

When you were a child, if you did your own experiment
to see if it was better to put to cocoa into your cup first
or the hot milk first, then you likely have the programmer gene..
