Howdy folks,
Alan Belkin has written some very useful and cogent guides to various aspects of music. You can find his home page here
http://www.musique.umontreal.ca/pers...n/e.index.html
Scroll down the page, and you'll find links to his writings on composition, orchestration, and some other topics. These can be read on-line, or downloaded for printing in PDF format.
I've found them helpful in my growth in musical understanding.
ttfn,
Sherry
