[ PREV | TIME-LINE | NEXT ] (The original video documentary covering this segment can be viewed here.)

Although the Music Animation Machine can use color to show which instrument is playing, it can't show what an instrument actually sounds like. To do this, I developed a new kind of spectrogram (which I call Voice Tracker ), one that shows small deviations in pitch, and shows the amount of energy in the harmonics of a tone which determines its timbre:

One idea for this is to have the scrolling Music Animation Machine display showing the notes of an instrument like the piano that can't vary its tone, combined with this spectrogram display, showing the subtleties of pitch and timbre of another instrument, or the human voice.
