If you enjoyed this article, you should read "Relating Tuning and Timbre" (http://sethares.engr.wisc.edu/consemi.html http://sethares.engr.wisc.edu/consemi.html), which generalizes these ideas to tones with nonharmonic partials. I think it also does a slightly better job at explaining the underlying ideas clearly.
