Inspired by Watteau's painting, this work is a grand, virtuosic exploration of joy and dance-like motion. It is distinctive for its complex, dense textures and rapid, shimmering figurations that build toward a triumphant conclusion.
The technical demand centers on the endurance required for rapid, wide-ranging figurations and the control of grand, climactic chordal passages.
