Benny Sluchin has done a superb job of collecting numerous studies, etudes, solos, and duos for various instruments and making them available for the alto trombonist. These prove to be invaluable source material to assist the developing as well as proficient alto trombonist. Many of the etudes originate with composers well known to trombonists, Bordogni, Bleger, and Kopprasch to name a few.

Volume one is intended for students learning the alto and forms a solid basis for playing the instrument. The etudes become progressively more difficult throughout the book and into volume two. Volume three is largely duets that focus on intonation while the last volume consists of solos transcribed from various sources. This set of books is a must for those interested in learning or furthering their playing on the alto trombone.
