In 1776, Wolfgang Amadeus Mozart composed three piano concertos, one of which was the Concerto for three pianos and orchestra in F major, No. 7, K. 242. He originally finished it in February 1776 for three pianos; however, when he eventually recomposed it for himself and another pianist in 1780 in Salzburg, he rearranged it for two pianos, and that is how the piece is often performed today. The concerto is often nicknamed "Lodron" because it was commissioned by Countess Antonia Lodron to be played with her two daughters Aloysia and Giuseppa. The third piano part, intended for the younger daughter, is more moderate in its technical demands.
