The book is laid out in a clean, easy-to-understand format. Mr. Griffin is obviously a gifted teacher, and has developed a book that would be a great resource for any music teacher or student interested in understanding and implementing more complex theory/harmony concepts." - Natalie Wickham, Music Matters, USA.
