Mozart - Adagio K261 - Violin/Piano Accompaniment Breitkopf EB2868
From a letter sent by Leopold Mozart to his son, it would appear that Wolfgang Amadeus delivered this Adagio as a single movement to the Salzburg violinist Antonio Brunetti in 1776 after Brunetti found the original middle movement "too scholarly." There is considerable evidence to support the claim that the present piece is an alternative middle movement intended for the well-known A-major Violi Concerto K219. Ultimately, the composer decided to leave the work (written in 1775) as it was, without change.
