Warming Up for Violin, Book One combines exercises with pieces at a third-year playing level. Each exercise and song is included as version A for lower level players and as version B for higher level players. Both version A and version B can be played together, allowing students of different levels to play and learn together in the same class. The book can be used as part of a string class, in conjunction with Warming Up for Viola, Book One, Warming Up for Cello, Book One, and Warming Up for Bass, Book One.
