These Twenty-One Christmas Carols are a fun-to-play collection of well-known Christmas and holiday songs arranged in a flexible style, with a traditional feel and a dash of contemporary flavor. Each song is fairly short, but can be repeated as many times through the verses as desired. An optional introduction is notated for each song.

The three books can be mixed and matched to accommodate any two brass instruments (and even some non-brass players). Transpositions are available in B-Flat for trumpet and treble clef baritone, F Horn, and bass clef for trombone, baritone, and tuba.
