The Piano Concerto No. 8 in C major, K. 246, or Lützow Concert was written by Wolfgang Amadeus Mozart in April 1776 in the same year as the Haffner Serenade. Countess Antonia Lützow, 25 or 26 years old, second wife of Johann Nepomuk Gottfried Graf Lützow, the Commander of the Hohensalzburg Fortress, was a fine pianist. The solo work is not highly demanding, but it requires agility. Mozart played the concerto in Mannheim and Munich on October 4, 1777, and used it for teaching. Three different cadenzas have survived of varying difficulty, accommodating the abilities of performers from student level to professional: one for two pianos.
