Dr. Charles Colin and Aaron Harris teamed up to write this wonderful technical study book that includes 40 brand new etudes. These studies are technically demanding, and were designed to develop a sense of style for solo performance. These studies challenge a player's endurance, tonguing, command of articulation, and all around technical facility. This book is a part of the Charles Colin Complete Method, a set of 7 books written to cover all areas of study for the modern trumpeter.
