Another piece curated by The Mozart Project, this sonata was written between 1773 and 1774 in Salzburg, Austria. Mozart had written the piece for him and his sister, Maria Anna Walburga Ignatia Mozart (nicknamed “Nannerl” for short) to perform together. The movements included are Allegro, Adagio, and Molto presto and is considered an important piece for all duet piano players.
