Here is what Professor Hinterbichler says about his Etudes:
"These etudes are based on some of the most often requested excerpts required at auditions. They cover the same basic material as the original with the added dimension to hopefully allay the tedium often associated with the prolonged practice of these short excerpts. Additional melodic material from a particular piece is often quoted, giving the trombonist a better overall sense of the music. All the etudes are in some ways more difficult than the originals. They work on range, technique, rhythm, control, articulation, intonation, endurance, dynamics, practice strategies, focus, phrasing and musical style. The goal is that by practicing and mastering these etudes, the playing and performance of the excerpts becomes less intimidating and more self-assured."
For advanced performers, this book is a must for serious orchestral musicians. -the publisher/cdp
