12 Christmas Duets by Kenneth Baird is a delightful collection of intermediate to advanced level duets based on traditional sacred and secular Christmas carols. (Please note: These duet collections are arranged so as to be instrument-specific and are not compatible with each other.)
They are challenging at times (not for beginners) without being overwhelming; at times joyful, at times uplifting, at times serene. In addition to being a great resource for teachers to play at lessons with their students, these duets are suitable for informal Christmas performances and many are appropriate for church services.
Included are: Away in a Manger; Deck the Halls; Hark! The Herald Angels Sing; Joy to the World; O Come All Ye Faithful; O Come, O Come Emmanuel; O Holy Night; O Little Town of Bethlehem; Silent Night; The Wassail Song; We Wish You a Merry Christmas and What Child is This?
