In ancient Greek mythology, the muse Terpsichore, a daughter of Zeus and Mnemosyne, is the goddess of dance and delight. With her in mind, I have sought to sculpt music that allows our individual and collective creative work to turn freely in the air. Terpsichore's Box of Dreams is by turns lively, sprightly, spry, energetic, vigorous, it is animated, traveling, flexible, versatile, changing, fluid and buoyant. While this is not exactly a "concerto for ensemble," each of the thirteen musicians is featured in several soloistic, virtuosic passages. What will pop out of Terpsichore's box next?
