Written in the late Renaissance period by Tomas Luis de Victoria, this beautiful piece captures the wonder and mystique of Christ's birth. Russell Robinson has arranged O Magnum Mysterium, making it more accessible to both school and church choirs, by setting it in a slightly higher key than the original, and with notation that is more easily understood. The music of the Renaissance has a pure clarity of sound that every singer should experience. Capture the wonder of Christmas and the holidays with O Magnum Mysterium.
