Symphony No. 38 in D major, K. 504

Adagio, then Allegro. The long slow introduction begins with a unison D and a drum roll, then moves through dissonances and shifting keys over a long pedal note on A. The Allegro starts with a quiet theme over syncopated accompaniment. Instead of a second theme, the first theme comes back in A major, and the real second theme only arrives later. The development never uses that second theme. A false recapitulation comes before the true one.
