Detailed Description

Pitch is represented as a combination of the step of the diatonic scale, the chromatic alteration, and the octave. The step element uses the English letters A through G: in a future revision, this could expand to international namings. The alter element represents chromatic alteration in number of semitones (e.g., -1 for flat, 1 for sharp). Decimal values like 0.5 (quarter tone sharp) may be used for microtones. The octave element is represented by the numbers 0 to 9, where 4 indicates the octave started by middle C.
The MusicXML pitch element is defined in note.dtd.
