Rounds – Hey Ho and Shalom Chaverim for 3 melody instruments (2 treble 1 bass.)
O Come Little Children – one verse optional accompaniment.
Dona Nobis Pacem – round in same format as above “Rounds”
God Rest Ye – countermelody
Holly and Ivy – harp & flute
He Is Born – harp & flute
Angels Song – this is by Rutter. I typeset it for my own use a few years back so that there are less page turns. It is free for harpists who wish to use it in performance. Might work for piano, too. This has some harp specific edits.
