Piano Concerto No. 20 in d minor, K. 466

• Mozart wrote this concerto, along with (most of) the rest of K449 to K503, between February 1784-December 1786 for concert opportunities in Vienna.¹
• This concerto premiered in Vienna on February 10, 1785, at the opening concert of a subscription series Mozart put on at the Mehlgrube, a casino and performance venue.²
• Mozart’s father wrote that this particular concerto (like many of Mozart’s works) was barely finished in time for its premiere. 

“Your brother did not even have time to play through [the rondo] as he had to supervise the copying.”

Leopold Mozart, letter to Anna Maria Mozart, February 16, 1785³
