Trumpet \Trump"et\, n. [F. trompette, dim. of trompe. See
   Trump a trumpet.]
   1. (Mus.) A wind instrument of great antiquity, much used in
      war and military exercises, and of great value in the
      orchestra. In consists of a long metallic tube, curved
      (once or twice) into a convenient shape, and ending in a
      bell. Its scale in the lower octaves is limited to the
      first natural harmonics; but there are modern trumpets
      capable, by means of valves or pistons, of producing every
      tone within their compass, although at the expense of the
      true ringing quality of tone.
      [1913 Webster]
