The course of Harmony is based totally on the “Treatise of Harmony” by Arnold Schonberg. According to him, “Harmony is the study of simultaneous sounds(chords) and of how they may be joined with respect to their architectonic, melodic, and rhythmic values and their significance, their weight relative to one another”.
The reason we chose this book comes from Schonberg himself: “The outset required the pupil to determine the sequence of chords himself […] This procedure has the advantage that from the very beginning the pupil is himself, in a certain sense, composing.” All the fundamental topics to develop from scratch a solid knowledge in Harmony are presented impeccably and logically mixed with his ideas and with philosophical overtones that enrich the contents entirely not just to follow the rules but ponder upon them.
