The Ensemble Books contain eight 4-part ensembles, carefully coordinated with material in the Lesson Books. Part 1 is a selected favorite from the Fun Book or the Recital Book. Parts 2, 3 and 4 use the same concepts and hand positions at the same level of difficulty. Includes suggested electronic sounds for those ensembles using electronic instruments. "Come Fly," "The Popcorn Man," and "Rock Anywhere!" are Federation Festivals 2016-2020 selections.
