Hymns and Carols for Worship is a collection of some of the world's finest hymns and carols, delightfully arranged in fresh settings. Written with the intermediate vocalist in mind, this product is designed to be accessible, yet interesting. The accompaniment CD (included with the book) provides a demonstration performance of each solo. It also allows the vocalist to practice or perform with the CD when an accompanist is not available. There are 2 versions of each accompaniment track Ð one in the key published in the book, and one in a higher register.
