The Adagio in E for Violin and Orchestra, K. 261, was composed by Wolfgang Amadeus Mozart in 1776. It was probably a replacement movement for the original slow movement of his Violin Concerto No. 5 in A. It is believed that Mozart wrote it specifically for the violinist Antonio Brunetti , who complained that the original slow movement was "too artificial." The work is scored for solo violin, two flutes, two horns and strings.
