The Progressive Duets for Strings is a comprehensive publication of two volumes of graded duets that have been arranged or composed by Larry Clark and Doris Gazda. Larry and Doris have drawn on their extensive experience as school music teachers and prominent composer/arrangers to create a collection of duets that will be useful in a variety of performance situations. Playing duets is an excellent way for the student to build ensemble skills with a colleague or teacher. It is published for violin, viola, cello and bass, and is arranged so that it can be performed by any two of these string instruments, making the collection a valuable tool in the school classroom as well. It is a collection that is long overdue.
