Based on the version used by the Army field bands.
Written in the key of Bb with trumpet 1 on melody but also transposed to the keys of Ab and C.
Also included is an alternate trumpet 1 descant part to be used when accompanying a soloist
and not needing the melody to be played.
Listen to a synthesized sound clip.
Check out a video by The Beltway Brass Quintet with guest vocalist DC Washington. (version in C)
