Selected Duets for Trumpet, Page 4 Number 3, Canon, performed by David Summer.
A musical "cannon" is an imitation of sorts. Here, the first trumpet part begins with the melody and the second trumpet part imitates that melody a measure later. This "delay" in the second trumpet part sometimes proves a challenge for students to keep their place in the piece. This is a good duet to have the student and teacher switch parts, with the student taking the second trumpet part, after they have played through the duet twice.
Since this trumpet duet is particularly short, the entire duet is repeated. The metronome setting for this performance is quarter note = 100.
