This section of the site contains various papers and documents (in pdf format) that go into the theory of tonality, and related subjects like tuning theory, in somewhat more depth than the rest of the site. At present, all items on this page should be considered work in progress.
Tonal Function in Harmonic Scales - this paper explains the origin of tonal functionality in scales designed for music using major and minor triads.
X_System - this paper was commissioned by Jim Plamondon of Thumtronics, and co-written by myself, Bill Sethares and Jim. It is a system of mapping just intonation to a two dimensional button-lattice using regular temperaments - and whole lot of other stuff too!
