Tancredi's opening Sinfonia, an exciting introduction, is borrowed from the overture to La pietra del paragone. The slow introduction, marked Andante marcato, duly leads to an Allegro, its first theme initially entrusted to the strings, followed, after a dramatic transition, by the second theme, introduced by flute and clarinet, soon joined by the bassoon. A characteristic crescendo is followed by a recapitulation, the second theme now initiated by the oboe and first violins, leading in due course to the final coda.
