Joseph Haydn'sKeyboard Concerto No. 11 in D major (Hob. XVIII/11) was written between 1780 and 1783. It was originally composed for harpsichord or fortepiano and scored for an orchestra in a relatively undeveloped galant style evident in his early works, and has a lively Hungarian Rondo finale. On the other hand, being a somewhat later composition, it also shows more similarities to Mozart's piano concertos than do Haydn's other keyboard concertos. It consists of three movements:
Un poco adagio
The first and second movements contain cadenzas. The original cadenzas, written by Haydn himself, have survived.
Perhaps surprisingly, the Rondo that Haydn calls "in a Hungarian style" has few Hungarian musical features, and more of the clashing semitone chords of Turkish music, although the orchestra uses none of the usual Turkish instrumentation. Towards the end of the movement Haydn briefly quotes Mozart's famous "Rondo alla Turca".
