Notes from the class today:

A pvc tube was cut and played like a flute (mechanical sound). The same pitch was played on a theremin (analog electronic sound). And also via a software oscillator executing in real time (digital sound).

Speed of sound was measured in the backyard. Two mics were spaced ten feet apart and a clap recorded near to one of them. The stereo file showed a 10msec. delay to the second mic.

The first homework was assigned and various organizational topics discussed.

We watched the first 20 mins. of Theremin, A Musical Odyssey.
