Subtitled "After Ernst Sachse's 100 Etudes for Trumpet," this book takes the study of transposition to a new level by requiring transpositions on a "moving" (phrase by phrase) basis, as well as by complete etude. Each etude is given twice - once with moving transposition and once without. This book is based on a system that Mr. Vacchiano learned from his teacher (Max Schlossberg) while a student at the Julliard school. 112 pages. --cdp
