The concerto for three pianos by Mozart 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.
This Concerto has three movements, Allegro, Adagio, and Tempo di minuetto, and the scoring is for 2 oboes, 2 horns, 3 solo pianos and strings.
