Selected Duets for Trumpet, Page 10 Number 2, Christmas Song, performed by David Summer.
This is another simple duet with an interesting tempo marking. Little clue is giving to the origin of this duet. Perhaps it celebrates Sinterklaas, the Dutch figure that formed the basis for the North American figure of Santa Claus.
Because it's a short duet, I've repeated the entire duet and the metronome setting for this performance is quarter note = 132.
