An Old English Christmas for Hammered Dulcimer

This seems like a valuable book. I would add "How Great Our Joy."

Thia book is filled with lovely arrangements for the intermediate hammered dulcimer player. The songs are arranged with simple chords, partial chords and grace notes. The songs included are some of the less familiar ones. Since the book comes with a CD you can learn the ones you don't know. Unlike some of the other learning books, this companion CD gives an idea of how the arrangement sounds with other instruments (you can hear the dulcimer clearly, however).

These look like nicely arranged tunes as you would expect from Linda Thomas. The problem is these tunes are not known in the US.
