Two Duos for Violin and Viola, KV 423/424

composed by Mozart

Mozart composed two Duos for violin and viola, No.1 in G major, KV423, and No.2 in Bb major, KV424. The close friendship between Joseph Haydn (1732-1809) and Mozart is very famous. Mozart was very close to also Joseph’s younger brother, Michael Haydn (1737-1806). In 1783, Michael Haydn was ill and incapacitated to compose two Duos for violin and viola. He had finished four duos to order for the archbishop of Salzburg, however he the order was six. Mozart composed two inspired duos, KV423 and KV424, to save Michael Haydn.
