Working on my figure drawing precision. Pencil (2B) for a change from charcoal.

The "circles of curvature" of the curve with polar equation r = sin θ -0.5cos 3 θ.
February is over, and I made six tracks, a whisker under 31 minutes, of sound for RPM 2015.
You can listen to them on Soundcloud.
You can also download the whole thing in one zip file, so you can add it to your music library and listen over and over again.
Here are descriptions of the six tracks.
There is a series of 18 tones here, each a small-denominator rational multiple of the last, that plays in a cycle with each tone given differing lengths so as to cause a varieties of harmonies.
This was made with perl-script-generated Csound score. I used aleatoric vibrato, which I think works pretty well, and was certainly easy to implement.
A piece of Perl code modified a recording of one of Eleanor Roosevelt's speeches. A stretching kind of thing.
A bunch of oscillators interacting, plus a bunch of filters interacting with the output of the oscillators to make a nice swimming kind of feeling with occasional sharper concentrations of frequencies. Just Csound.
A large bank of rather simple oscillator start at arbitrary pitches, converge to some chord at about mid-track, then converge on a single tone at the end. Lots of beat frequencies. Csound.
Noise. I have a game I play where I try to write the simplest piece of code that generates (what I think is) interesting sound. This one was made with a few lines of perl code, all modular arithmetic and comparisons, no trig or random number generators. I like a lot of the timbres.
Choose between random nouns. Variable delays, ring modulation, plus filters. I think it amusing that the manipulation of the synthetic voice causes the synthetic voice ultimately to sound more natural.
