The famous French Christmas Carol (GLORIA) set for trumpet septet. Yes, seven Bb trumpets. This piece was requested by a trumpet group and it turns out it is easier to write for this ensemble than one might think.
This piece starts out with a sort of baroque feel with answering fanfares in between the hymn tune phrases. The Gloria chorus is a chorale fantasy. The main body (stanza and chorus) repeat and then transition to a higher key and switch to 3/4 time and slows to become a stately polonnaise. Of course, there is a big ending.
Since the parts are written in treble clef, other groups of like instruments reading treble clef in the same octave and transposition do this. The lowest written note is a G below middle C.
