Keyboard Concerto No. 11 (Haydn)

Joseph Haydn's Keyboard Concerto in D major, Hob. XVIII:11, was written between 1780 and 1783 and published in 1784, his last concerto for keyboard. He composed it for harpsichord or fortepiano, scoring for orchestra in the relatively undeveloped galant style of his earlier works, but, being a somewhat late composition, the work has similarities to Mozart's piano concertos; Haydn and Mozart had probably become acquainted by 1784.

(Mozart returned from Italy in 1773, at the age of seventeen, and turned to the piano concerto form in 1776. Biographers and historians have suggested that this Haydn work reflects Mozart's influence. Mozart acknowledged the important role of Haydn in the development of music and in correspondence often referred to him as "Papa Haydn".)
