An up-tempo romp through several keys, this is a light-hearted piece with good separation, swing notes and a nimble style. On trombone, with the use of a mute, the echo effect at letter A should take care of itself. The solo at C in the third part might be turned into a jazz improvisation, if there is someone that does that sort of thing. The most enthusiastic playing should be saved for letter F. Have a good trip!
