String Orchestra - Level 2 - Digital Download SKU: A0.971971 Composed by 13th Century Plainsong. Arranged by Alisa Tomlinson. Christian,Christmas,Classical,Contemporary. Score and parts. 13 pages. Alisa Tomlinson #3113541. Published by Alisa Tomlinson (A0.971971). Completely instrumental, this arrangement uses string orchestra and glockenspiel to accompany a harp soloist. The arrangement features a section where both of the melodies interweave with each other. I believe it is a fresh take on an old favorite.
