The Violin Concerto No. 3 in G major, K. 216, was composed by Wolfgang Amadeus Mozart in Salzburg in 1775 when he was 19 years old. In a letter to his father, Mozart called it the "Straßburg-Concert". Researchers believe this epithet comes from the motive in the third movement's Allegretto in the central section, a local dance that already had appeared as a musette-imitating tune in a symphony by Carl Ditters von Dittersdorf.
