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.
% T = music.note2tone('F#6') % returns 30
% See also music.note2freq, music.note2interval, music.tone2note.
