Title: Symphony No. 40 (Mozart)
Content:  Symphony No. 40 in G minor, K. 550 was written by Wolfgang Amadeus Mozart in 1788. It is sometimes referred to as the "Great G minor symphony", to distinguish it from the "Little G minor symphony", No. 25. The two are the only extant minor key symphonies Mozart wrote.

The contrasting gentle trio section, in G major, alternates the playing of the string section with that of the winds.

However, there is no proof in the sources to support his thesis. Also, K. 409 calls for two flutes in its orchestration which does not match the rest of the symphony. The finale is in sonata form and features energetic tarantella or saltarello rhythms. The autograph score is today preserved in two halves: the first half (f.1-18) is in the Bibliothèque nationale de France, and the second half (f.19-28) is in the Biblioteka Jagiellońska, in Kraków.

A more subdued trio written primarily for strings (with a bit of oboe). ; 1) [Allegro] ; The fourth movement, also in D major, is a long dance in time cast in sonata-allegro form. Though Mozart himself did not label the tempo of the fourth movement, the character of the piece and the standard symphonic form of the time indicates that Mozart probably intended the piece to go at an "allegro" tempo. The symphony is scored for one flute, two oboes, two horns, two trumpets and strings.  There are four movements:

The first item on the program was billed as "A Grand Symphony composed by Herr Mozart". As Neal Zaslaw has pointed out, writers on Mozart have often suggested – or even asserted – that Mozart never heard his 40th Symphony performed. Some commentators go further, suggesting that Mozart wrote the symphony (and its companions, Nos. 39 and 41) without even intending it to

Content:  The date of completion of this symphony is known exactly since Mozart in his mature years kept a full catalog of his completed works; he entered the 40th Symphony into it on 25 July 1788. Work on the symphony occupied an exceptionally productive period of just a few weeks during which time he also completed the 39th and 41st symphonies (26 June and 10 August, respectively). Nikolaus Harnoncourt conjectured 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. The 40th symphony exists in two versions, differing primarily in that one includes parts for a pair of clarinets (with suitable adjustments made in the other wind parts). Most likely, the clarinet parts were added in a revised version. The autograph scores of both versions were acquired in the 1860s by Johannes Brahms, who later donated the manuscripts to the Gesellschaft der Musikfreunde in Vienna, where they reside today.
