It makes a pitch. A pitch is a data type in LilyPond's Scheme that has
an octave, a notename (actually a whole number within the scale), and an
accidental (a rational measured in terms of whole note fractions,
typically -1/2, 0, or 1/2). It is one of the two basic constituents of
a note, the other constituent being a duration.
