Dynamic Tonality References

An online version of the Winter 2007 CMJ article introducing tuning invariance can be found on the CMJ’s website, here (the CMJ’s “one free article per issue:”)

A second article, comparing & contrasting various tuning invariant keyboard note-layouts using various metrics, was accepted by the Journal of Mathematics and Music (for publication in Spring 2008). The version submitted for peer review, which does not include changes made to reflect the excellent feedback provided by its reviewers, can be found here:

Both of these papers refine, and expand on, ideas first documented in this omnibus paper:

The name “X_System” was just a placeholder until we could think of something better. The new name is “Dynamic Tonality,” which embraces Dynamic Tuning, Dynamic Timbres, and Dynamic [Whatever].

The musical potential of Dynamic Tonality is summarized here:

A (crude, buggy) Max/MSP-based synth demonstrating Dynamic Tonality, using the computer keyboard as its musical input device, can be found here:
