Wolfgang Amadeus Mozart's Piano Concerto No. 9 in E♭ major, K. 271, known as the Jeunehomme or Jenamy concerto was written in Salzburg in 1777 when the composer was 21 years old.
Mozart completed the concerto in January 1777, nine months after his Piano Concerto No. 8 in C major and with few significant compositions in the intervening period. He composed the work for Victoire Jenamy, the daughter of Jean-Georges Noverre and a proficient pianist. Mozart performed the concerto at a private concert on 4 October 1777. Jenamy may have premiered the work earlier.
