Christoph Willebald Gluck, whose reputation is based on his record as a reformer and innovator in the world of stage works, wrote two important ballets. One is the well-known Semiramide (1765), and other is Don Juan (1761), his first reform work, which was the forerunner to the famous opera Orfeo. This suite consists of the sinfonia (or overture) and two selected movements from the seven movements contained in the incidental music to the ballet. Common dance forms from the period include the popular minuet, in addition to the sarabande, allemande, courante, and gavotte. The two dances in this arrangement are the allemande, a dance in 4/4 time that almost always begins with an upbeat, and has eighth notes grouped in pairs, and the gavotte, also in 4/4 time.
