Haverstick’s first book, “The Form of No Forms,” was written in 1984, and covers Western music theory from basic scales and chords, to complex jazz progressions, modes, and polytonal concepts. His most recent offering, “19 Tones:A New Beginning,” is a look at the 19 tone equal tempered system, it’s relation to the 12 tone eq system, and how they are both approximations of the ratios of the Harmonic Series.
