Sluchin, Benny - Alto Trombone Tutors Volumes 1,2,3 and 4

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.
