The Symphony no. 34 in C, K. 338, was written by Wolfgang Amadeus Mozart in 1780. It has three movements, which was still common in the early classical period. The symphony features the fanfares and flourishes typical of the "festive symphony" or "trumpet symphony", which is characteristic of Austrian symphonic writing in C major. This is the first of Mozart's C major symphonies to exhibit this character, but the style would be revisited in his subsequent two works in this key, the 36th and 41st symphonies. The first movement is written in sonata form but also contains many styles and formal aspects of an Italian overture. There is no expositional repeat. The expositional coda contains an overture-like crescendo which is not included in the recapitulation. The development is based entirely on new material. The recapitulation on the exposition's first theme is abbreviated and interrupted by a brief development of that theme. Finally, the movement's coda contains nearly all of this first theme creating the appearance of a reverse-recapitulation common in Italian overtures. The work is scored for 2 oboes, 2 bassoons, 2 horns, 2 trumpets, timpani and strings.
