The Piano Concerto in D minor was written by Mozart between the third week of January 1785 and February 10 of the same year. The next day, his father Leopold Mozart arrived in Vienna from Salzburg, Austria for a 10-week stay. That evening, Mozart performed the concerto at the Mehlgrube Casino. Leopold wrote his daughter Nannerl: "We arrived at 1 o'clock ... the copyist was still copying the new concerto and your poor brother did not have enough time to play through the Rondo because he had to supervise the copying ... On the same evening we drove to the first of his six subscription concerts. A great many members of the aristocracy were present. They each pay three ducats for these Lenten concerts ... Your brother is giving them at the Mehlgrube ... The concert was magnificent and the orchestra played splendidly ... A female singer from the Italian theatre sang two arias then we had the new and very fine concerto." Mozart played the concerto again at the Burgtheater on February 15, 1785.
