I’ve only seen one harp arrangement of this (there certainly may be others out there!)
Christmas Classics
arranged by Darhon Rees Rohrbacher
A wonderful collection of Christmas music arranged in key order so that the entire collection can be played as a continuous suite, if desired. Lever and pedal changes are well-planned and well-marked. Keys of F, C, G, and D major (or relative minors). Pastoral Symphony (both a pedal harp and lever harp version), Carol of the Bells, Silent Night, Coventry Carol, Bring A Torch, While By My Sheep. Dancing Day, Infant Holy, Still Still Still, Gesu Bambino (both a pedal harp and lever harp version). Though standards, these arrangements are new, refreshing, written in a nice harpistic style, and are very enjoyable to play.
