Pitch Constants

Note pitches are represented as in the MIDI specification, using integers from 0 (lowest pitch) to 127 (highest pitch). That’s a total of 128 pitches (i.e., 10 octaves).

The music library defines the following pitch constants for convenience.

First, there is a special pitch REST corresponding to rests.

Rests are notes that last as long as you specify (see duration constants), but produce no sound.

The lowest possible note is C_1 (C negative one); it is equal to 0. The highest possible pitch is G9; it is equal to 127.
