Christmas musical has organ accomp, and there's a Ch. near the top of the score a couple pages in. Was asked if I knew the meaning...and I don't. Any help here? Thanks.
When an organ has two manuals they are usually called Great (Gt.) and Swell (Sw.) A third manual may be called Choir (Ch.). "The Choir organ contains stops well suited for accompaniment or light solo work, especially when working with the vocal choir."
