Class: Pitch

.pitch. Pitch

new Pitch(pn)

Pitch objects are found in music21.note.Note objects, and many other places.

They do not have a music21.duration.Duration associated with them, so they
cannot be placed inside music21.stream.Stream objects.

Valid pitch name formats are

  • "C", "D', etc. ("B" = American B; "H" is not allowed)
  • "C#", "C-" (C-flat; do not use "b" for flat), "C##", "C###", "C--" etc.
  • Octave may be specified after the name + accidental: "C#4" etc.
  • Octave can be arbitrarily high ("C10") but only as low as "C0" because "C-1" would be interpreted as C-flat octave 1; shift octave later for very low notes.
  • If octave is not specified, the system will usually use octave 4, but might adjust according to context. If you do not like this behavior, give an octave always.
  • Microtones are not supported in music21j (they are in music21p)
