music.note2tone(N)

function T = note2tone(N)
% MUSIC.NOTE2TONE Converts a scientific pitch note to a tone relative to C4.
%   T = MUSIC.NOTE2TONE(N) returns T, the number of semitones above or below C4
%   at which note N occurs. N is a note string in scientific pitch notation, or
%   a cell array of strings.
