Piano Concertos no. 20 in D minor, K. 466 / No. 23 in A major, K. 488

Piano Concertos No. 20 in D minor, K. 466 and No. 23 in A major, K. 488 are piano concertos by Wolfgang Amadeus Mozart, composed in 1785 and 1786. They exemplify Mozart's mature Classical concerto style, contrasting the darker, dramatic character of the D minor work with the lyrical, poised A major concerto through intricate dialogue between solo piano and orchestra, and they are key works in his late concerto output and the Classical concerto repertoire.
