The supplementary books Duets with an Open String Part are available for violin, viola and cello. The duet books provide additional folk and traditional tunes with simple open string parts. The tunes may be sung or played by the teacher, a family member or a more advanced student on strings, piano or other instrument. The duet book can be used alongside Book One of the series to develop confident rhythm and bowing skills. Beginners make satisfying music right from the start – experiencing the fun of ensemble playing and learning the skill of keeping time. A lively duet is a great way to warm up, or to wrap up a lesson that will have many students saying, “Can we play that again?!” Most tunes from the Duets with an Open String Part books are in the same key for violin, viola and cello and can be used together in a group of mixed strings.
