Ralph Sauer's Practice With Bach will challenge your technique and musicality with demanding new etudes. Based on the keyboard works of J. S. Bach, these etudes are customized for performance on the alto trombone (choice of key, range, ornaments, etc.). Tenor trombonists will find that the Alto version is excellent for high register practice and alto clef reading. Likewise, Tenor trombonists can use the Bass version for low register work. Volume One contains 24 etudes in all keys, based upon preludes from The Well-Tempered Clavier. -the publisher/cdp
