Barbara C. Harris Camp & Conference Center Choir Camp singers lifting their voices in song. In its 15th year, Choir Camp presents singers from grades 4-12 an opportunity to travel the world in a single week! Campers learn about and sing music from across the centuries and around the globe:  baroque music, canticles, anthems, Spanish songs, gospel, African chant. It's a great chance to learn about church music and its traditions; the week ends with a Festival Lessons and Carols service.
