This six-part series begins with the basics and progresses through advanced harmony and arranging. Each book is complete text and workbook in itself containing 30 short lessons and assignments. Most work can be completed outside band rehearsals at the student's own pace. Review and grading can be done in less than 5 minutes of class time. This combination of home study plus just a few minutes of rehearsal time for theory will produce amazing results in a very short time.
