La valse, poème chorégraphique pour orchestre (a choreographic poem for orchestra), is a work written by Maurice Ravel between February 1919 and 1920; it was first performed on 12 December 1920 in Paris. It was conceived as a ballet but is now more often heard as a concert work. Frederick Ashton also created a La valse ballet in 1958 for The Royal Ballet.
Dr. Coppélius is a doctor who has made a life-size dancing doll. It is so lifelike that Franz, a village youth, becomes infatuated with it and sets aside his heart’s true desire, Swanhilda. She shows him his folly by dressing as the doll, pretending to make it come to life and ultimately saving him from an untimely end at the hands of the inventor.
