A companion text to Ottman's Elementary Harmony: Theory and Practice, 5/e, Advanced Harmony continues the course of instruction in basic music theory. Combined, these two volumes present a systematic study of the principles of harmonic composition as developed by the composers of the 17th to the 19th centuries. It takes the reader to a more complex level of materials—19th century through 20th century. The text applies an incremental learning approach to the academic aspect of music and applies newly acquired knowledge to the writing of music.
