Parts available for violin, viola, cello, and string bass. Here is a terrific resource for string students who already have the skills to read music using the fundamental notes and rests, and are ready to go to the next level of reading ability. Materials are flexible and can be individualized. Each unit includes assessment tolls, with a pre-test, unison exercises, a post-text and a three-part ensemble to "put it all together." The mix-n-match" ensembles provide even more sight reading practice for string orchestras or chamber ensembles.
