Choir
Accompaniment

Most Eastern Orthodox Christian churches, some American Protestant groups, and traditional Jewish synagogues do not accompany their songs with musical instruments. In churches of the Western Rite the accompanying instrument is usually the organ, although in colonial America, the Moravian Church used groups of strings and winds. Many churches which use a contemporary worship format use a small amplified band to accompany the singing, and Roman Catholic Churches may use, at their discretion, additional orchestral accompaniment.
