Traditional staff-based pitch notation is difficult to incorporate
into text. In this work, a completely equivalent textual
representation, as suggested by the Acoustical Society of America,
will be used. The following explanation is adapted from
[13, xiii]. Pitches will be identified by class and
register. Class will be symbolized by a letter in the
set {A,B,C,D,E,F,G} followed by any number of sharp (
) or flat
(
) signs. Register will be symbolized by an integer following the
class. A register refers to all pitches that can be notated on the
area of the staff from a given C to the next B above it. Defined in
this way, any B has the same register as the B that is its
natural version; thus in 12TET B3 sounds the same as
C4. Likewise, any C has the same register as the C that is its
natural version; thus in 12TET C4 sounds the same as B3. Middle C
is C4.
