Very fine and understable guide to composition in jazz idiom - it assumes that you already have enough knowledge of harmony/chord-scale theory so I'd not recommend it for newbies in music. Anyway, glad to have obtained this one.
Don't buy a digital copy. My Kindle edition came as a PDF without any photos, musical examples or graphs. Most of the book was missing. Luckily I could get it from the library. The info is in depth but presented in an easily digested way. Pease includes fantastic lists of songs you can listen to as examples of each topic covered.
