CONTRIBUTOR: By Gerald Bordner This book of original exercises is the sequel to the first book in this series. The etudes are a mixture of the rhythmic pattern and solo type. Problems of rhythm, technic, and range are dealt with logically and progressively and and with ample preparation. In the case of the trombone, special emphasis was placed on writing exercises which would allow economy of slide movement through the use of substitute positions. The book is intended to be supplemental in nature and should be a value to the student by supplying additional material in certain developmental areas encountered in the students regular method book.
