Mozart Symphony No. 40 (com.mozart40) on Google Play
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.
