This book has been designed as a supplementary study to be used along with any standard instruction book. The studies contained herein are excellent for use in the warm-up period prior to each daily session of practice. The technicality of the fingerings and slide positions (trombone slide positions appear above the notes; baritone fingerings appear below the notes wherever considered helpful) are comparatively simple and the studies can be used to advantage by a young student with only a few weeks of formal study. This book contains much valuable material essential to successful performance not found within standard instructional material.
