I have to admit, it's hard to believe there's that much to say about music theory that such a book could be worth $59.53 new. Of course, * notes are largely determined by frequency, i.e. a real number; * the human ear perceives a doubled frequency as "the same note", kind of; * it also perceives combinations of notes with frequency ratios being fractions with small denominators as pleasing. Beyond this, it's all experimentation with what sounds good. (On the other hand, there are some extremely complex musical traditions. Some (East) Indian music relies on a scale of 40+ notes, and there is much to be said about it. Though I wouldn't call it "theory".) --Dan Hilarie wrote: << I've come across a book of essays titled "Music Theory and Mathematics" which includes writing by Jack Douthett, John Clough, et al. Is anyone here familiar with their work?
