This is a four-part fantasia mostly around the familiar rondeau melody the composer mentions, by the French Baroque composer Jean-Joseph Mouret (1682-1738) in his "Suites de Symphonies". Each voice gets in on the action with equal weight, and the activity ramps up during the latter half. The melody gets put through a fun-house mirror, twisted around into various harmonic contortions, while layering its own fragments upon itself in other parts. Baroque-style gestures and tight interplay help earn the composer’s designation as “Challenging”, and the increasing complexity along the way echoes the consort fantasias of the English Renaissance as they spiral out of control. Great basses are not in all groups’ instrument arsenals, but if your group has one, this piece is worth putting it together.
