Abjad Note and Chord instances accept both pitch token instances and Abjad NoteHead instances as input.
For example:
abjad> note = Note(0, (1, 4))
abjad> note.notehead = 13
Abjad groups pitch token instances and Abjad NoteHead instances together under the heading of notehead token input.
Examples in the documentation that ask for notehead token input accept any of the input types shown here.
