There is considerable evidence to support the claim that the present Adagio in E major is an alternative middle movement intended for the well-known A-major Violin Concerto K. 219. Ultimately, Mozart decided to leave the work (written in 1775) as it was, without change.The violin part of the present edition contains – also in the tutti sections – the upper part of the orchestra, thus leaving it up to the soloist to decide whether he should pause here or join in.
