- I apologize utterly if it sounded snarky... I find the chat on
- engineering systems interesting, if a little remote to my field (
- which is composition ). For instance, I have no idea what a Radon
- Transform is.
- I do, however, know a bit about the perception and performance
- of music and have toyed with fuzzy set theory and music. I'm
- wondering about the possibility of applying fuzzy set theory to
- spectral pattern perception. An FFT is an example of the classic 19th
- century sound model which takes little account of what we know of
- perception. It is also calculation intensive, which reduces its utility
- for real-time music applications.
- I had one intrigued email response which asked for references;
- the only article I've ever come across was one
- on Fuzzy harmonizing of a melody, in last summers Computer Music Journal
- which treated the overtones of a piano tone as partial
- members of other notes according to their amplitude. The strategy is
- similar to the one I use for harmonic distance ( calculating the
- relatedness of sets of chords ). Other than this one article, which
- unfortunately made some presumptions about tempered tuning, I've
- not seen or heard of anyone working in fuzzy music.
-
- If any non-musicians make it this far, consider the oft-cited
- Zadeh example of a fuzzy instruction, the car-parking fuzzy
- instruction - in the realm of human activity this is an
- extradorinarily precise activity compared to for instance
- composing a melody. I would suggest that artists have a lot to
- contribute to an understanding of fuzzy logic and its utilization.
