Piano Sonata No. 11 (Mozart)
The A major sonata is unique among Mozart's piano sonatas. It does not include a movement in sonata form. The first movement is a lilting theme in 6/8 followed by six variations in A major and A minor. The last variation is in 4/4 time.  The second movement is a Menuetto in A major with a contrasting section (called a Trio) in D major. It is written in 3/4 time. The third and final movement is the famous "Alla Turca" (Turkish March or Turkish Rondo) in 2/4 time. It is considered one of the finest examples of Viennese Turkish music that was produced in the late 18th century. The rondo's rolled block bass chords suggest the drum rolls of a Turkish Janissary band. In true classical style, the rondo alternates between major and minor keys, and loud and soft dynamics. The piece is a favorite for amateur recitals.
