Two Clarinet parts are included Easy (much of the music is below the break, and graded at around grade 2-3), and a Standard edition (the range is a little more up to C above the stave, and an optional flamboyant ending up to top E if you wish, graded at around 3-5). Because of its nature, the piece can be shortened, and Carols omitted if programming time is an issue each Carol resolves individually so this is not a problem. This book also includes a CD which includes Tuning note, Demonstration guide (melody line and piano together), and piano backing only.
