Ballet in one act with choreography by Mark Morris, music by Virgil Thomson, and costumes by Santo Loquasto. Premiered 31 May 1988 by American Ballet Theatre at Metropolitan Opera House, New York, with Baryshnikov, Bocca, Jaffe, and van Hamel. This setting of Thomson's thirteen piano études takes its name from the famous 17th-century song and was Morris's third work for a classical company (commissioned by Baryshnikov). The dancers, dressed in simple white costumes, perform deceptively plain-looking ballet steps set in increasingly resonant patterns. It has entered the repertories of the Royal New Zealand Ballet, English National Ballet, Washington Ballet, and San Francisco Ballet (1996).
