The ~score Event provides three high level params.
chroma is the chromatic offset applied to all melodies. This is analogous to a "transposition" key on a keyboard.
cps is the cycles per second, aka BPM if you think about it. This is a tempo setting.
cpp is cycles per phrase. This describes the number of beats that go into the overarching muscal phrase. Powers of 2 work great (1,2,4,8,32...), just needs to be greater than 0.
The synthdefs are in the "lead", "chords", and "bass" files. The pbindef call is also in its synth file.
Loading this file will result in playback of a melody. This is how the score's autoloader expects it to work.
This also means you can test or edit individual melodies by running just that file.
