 The concerto is about 25 minutes in length, and is scored for solo piano, 2 flutes, 2 oboes, 2 clarinets, 2 bassoons, 2 horns, 2 trumpets, timpani, and strings.Unusually for Mendelssohn, who often produced his compositions quickly, the Second Piano Concerto took him a great deal of effort.Its genesis dates to the period shortly after his marriage and is first mentioned in a letter to his friend while on honeymoon
