Publisher Desc.  This publication is a compilation of three separate Christmas carols. They are not segued together into one rendition. However, they may be sung together, if desired. The carols are: O Christmas Tree, I Saw Three Ships, and What Child Is This? Each of the carols is homophonic and each is supported by a strong piano accompaniment. There are three verses to each carol. These carols are best suited for all-male groups due to the range and tessitura of each of the voice parts. They may be sung by mixed groups as well.
