This arrangement gives you a chance to include very early beginners, who play the “tick tock” (part 3) as a solo, or a “special” ensemble, with more advanced students who are playing at the level of Perpetual Motion (book 1 Suzuki). The cello and viola have a few notes in higher positions with optional divisi notes in 1st position. You can mix and match the parts to fit your players, as the 1st and 2nd parts are combined on the same page. When you get to the CODA, you can choose what players play what parts, and have the less advanced musicians to play letter C, which is easier than C1, or the official Coda.
Enjoy!
