I was reading about sound last night:
Timbre
Formant
Csound
I Am Sitting in a Room by Alvin Lucier
ubu.com - A really great resource for music and art

19. Vowels and Formants III: Formants for fun and profit (with samples of exotic music)
Why a wah pedal sounds something like a voice, and why it doesn't sound more like one
