Publisher Desc.  "Daily Workout: Key Studies and Practice Routine for Trumpet" by Kenneth Baird is a book for the intermediate/advanced player who is seeking a systematic method to insure that technical mastery in all keys is maintained. Included are: harmonic flexibilities (lip slurs), scale and arpeggio technical studies in all major and minor keys, multiple tonguing studies, jazz patterns, and hymn tunes for tone and expression. This book is conceived as: I. A developmental book for the intermediate player; developing fluency in patterns common to commercial and jazz styles as well as developing traditional "legit" technique. II. A maintenance book for the advanced player with only 30 minutes to an hour available for daily practice, whether at one setting or spaced throughout the day. III. A systematic maintenance book for the advanced player who needs to insure that technical mastery in all keys is maintained while spending a majority of his practice time on etude study or other musical preparation.
