Decide on truth values for the types in the language. Document these in some sort of table.

type true false
note not a rest rest
number > 0 0
boolean true false
reference defined undefined

Comparisons

Only supported between like types. Otherwise an exception is raised.

  • beat: longer duration is larger than shorter duration
  • Rhythm: radix comparison of beats
  • note: higher pitch is larger than lower pitch, rest pitch is absolute lowest
  • chord: radix comparison of notes
  • melody: radix comparison of elements. If different a chord is always larger than a note
