Piano concertos by Wolfgang Amadeus Mozart Piano concertos by Wolfgang Amadeus Mozart Wolfgang Amadeus Mozart wrote 23 original concertos for piano and orchestra. These works, many of which Mozart composed for himself to play in the Vienna concert series of 1784–86, held special importance for him.

They were championed by Donald Francis Tovey in his "Essay on the Classical Concerto" in 1903, and later by Cuthbert Girdlestone and Arthur Hutchings in 1940 (originally published in French) and 1948, respectively. Hans Tischler published a structural and thematic analysis of the concertos in 1966,
