A number of different shape note traditions remain in common use in the
shape note community. SMuFL encodes the noteheads required for four such
systems: one four-shape system; and three seven-shape systems (Walker,
Funk, and Aikin). All three seven-shape systems also use the four shapes
of the four-shape system, each introducing three additional shapes.

The four-shape system, used in books such as William Walker’s *Southern
Harmony* (1835), uses a form of solmization where the syllables *fa*,

*The New Harp of Columbia* by M.L. Swan defines a seven-shape system,
with the following shapes for each syllable:

For practical use, scoring applications should provide a means of
automatically substituting regular noteheads for the appropriate shape
note notehead glyph according to the pitch of each note.
