Implementation notes
---------------------

The so-called "sine" notehead was invented by Conlon Nancarrow as a more compact representation of a note five 8ths (quavers) or 16ths (semiquavers) in duration. It does not appear that Nancarrow ever gave this notehead a formal name, so we have named it after its resemblance to a sine wave.

This range also includes noteheads invented by Henry Cowell, first published in his book _New Musical Resources_ (1930). Cowell suggested using these noteheads to denote tuplet relationships without writing explicit tuplets.
