This is one of the few books in Spanish about contemporary harmony recommend both Volume 1 and 2, covering almost all of contemporary harmony, the items are sorted and you need to read from the beginning if you do not have basic knowledge of harmony,
which come explained in Volume 1 so there is no major problem, as I said in the title I think is a very important book for any serious musician in power since it serves for life.
