Note pitches are internally expressed with their respective MIDI pitch values. This corresponds to the absolute height of the note, regardless of the way it is actually written (enharmony; to retrieve the actual enharmony employed for a note, use its Tonal Pitch Class instead). The pitch is used by the Note.pitch property.
