The keyboard concerto in D major, Hob. XVIII:11, was written around 1780 and printed within a few years in Vienna, Paris and London — one of the few concertos Haydn saw through publication, and the only one of those still regularly played. It works equally on harpsichord and on the fortepiano then coming into general use. The finale is marked Rondo all'ungarese and draws on the dance music Haydn heard in the Hungarian lands around the Esterházy estates, the same repertoire that would reach Brahms a century later.
