My info is from various sources, but the basic stuff on pitch-class intervals is on Wikipedia etc. A good book on the basics is Foundations of Diatonic Theory, by Timothy a Johnson (2008), if you are interested. I also found this old link http://www.mta.ca/faculty/arts-letters/music/pc-set_project/pc-set_new/pages/introduction/toc.html, which I found very helpful. I have just bought Audacious Euphony by Richard Cohn (OUP, 2012), complex but very interesting. I’ve also subscribed to J Music Theory, which gives online access to all the older articles including some original source papers (John Clough and David Lewin are major players). Not much of this is specifically about jazz, and probably of no practical value for “the blowing”, and I’m only scraping the surface at the moment.
