The 40th Symphony of Mozart
The 40th Symphony was completed on 25 July 1788. The composition occupied an exceptionally productive period of just a few weeks in 1788, during which time he also completed the 39th and 41st symphonies (26 June and 10 August, respectively). Nikolaus Harnoncourt argues that Mozart composed the three symphonies as a unified work, pointing, among other things, to the fact that the Symphony No. 40, as the middle work, has no introduction (unlike No. 39) and does not have a finale of the scale of No. 41’s.
