Mr. Wehr has taken these wonderful etudes by the late David Uber and have transposed them downward so that the bass trombonist will have a more playable introduction and hopefully a more satisfying experience learning both the tenor and alto clefs. Whileneeded and useful for the intermediate to the advanced bass trombone student, these etudes also offer valuable and enjoyable melodic materials that are musically attractive to the teacher and student alike. -the publisher
