"Structure in Sound" is a new theory of harmony which contains new chords mapped by a new system of musical notation which encompasses traditional theory. Two devices transcribe the system into regular musical notes: the slide scale and the circle scale. Cardboard versions of these have been patented. Used in conjunction with a dictionary of scales (comprising dozens from all over the world, like the Chinese Ming Dynasty scale and the Hungarian Oriental Scale), the new system can create new harmonies which have previously only been heard by accident.
