Here are some links which you may find useful.

Tuning Systems

For my own essay on tuning see Tunings.  If you require further reading on tuning systems try the following sites :-

For a thoughtful, reflective and extensive article on Pythagorean Tuning and Medieval Polyphony there is an excellent article by Margo Schulter.  Her article is primarily from a musical and historical perspective.  Covers the development of just intonations, mean, and equal temperaments in the context of musical necessity.

For a comprehensive collection of links to microtonal web sites including the people involved and audio samples see John Starrett's Microtonal Music Page.

For extensive tuning data, tables of microtonal synthesizers and more see Microtonal Synthesis Home by John Loffink.

For modern theory of tonality see John Chalmers' web site.

For a dictionary of musical terms and tonality theory see Joe Monzo's web site.

For a very readable introduction and more see Tuning for Beginners by Graham Breed.

For a brief summary article with audio examples see The Mathematics of Tuning and Temperament With audio examples by David Bartlett.

For an exposition of the relation of Fibonacci series to musical scale structures and the theoretical basis for scales with other than 12 notes per octave see Mathematical representations of musical tunings by John S. Allen.

Microtonal Music

For microtonal music to listen to try Andrew Heathwaite's Microtonal Listening List.

Audio Synthesis

If you require further reading on audio synthesis try the following sites :-

Tutorial for Frequency Modulation Synthesis by Barry Truax.

Synthesizers, Music & Broadcasting by Yala Abdullah.

Fourier Theory

For an excellent intuitive (non mathematical) explanation of Fourier theory and the discreet Fourier transform (with source code) see Mastering the Fourier Transform in One Day by Stephan M. Bernsee.

For a helpful series of tutorials on the Fourier series, time and frequency domains, sampling and aliasing and the Discrete Fourier Transform see Vibrational Analysis Theory.
