A must have!
This is an essential book to fully understand harmony for the advanced student in the subject. It is not designed for beginners but for the one that already know the subject quite well and, ideally, has studied with Schoenberg's treatise on Harmony. In terms of the language, it is quite clear, although extremely dense (Schoenberg's treatise on Harmony is resumed in four pages at the beginning) and perhaps a bit arid from time to time. However, the clarity of the musical concepts and, most of all, the beauty of the musical examples make the book a "must have" in a musician's reference library.
