Vivaldi composed the Concerto for Two Trumpets in C major possibly in the 1720s in Venice.

It seems unlikely that he wrote it for the Ospedale della Pietà, because the ensemble there comprised voices, strings and keyboard.

[3] In the first movement, the strings modulate to a minor key, which returns to the major when the trumpets re-enter.

In the middle movement of only six measures, the trumpets are silent,[3] with both the style and harmony being unsuitable for the instrument.

[2] The third movement, beginning with fanfare arpeggios in canon from the soloists, is in a triple metre and brings the work to a vigorous conclusion.
