The word choir can also mean the part of a church or cathedral where the choir sit. The choir is between the nave (the main body of the church) and the sanctuary (where the altar is). The singers will divide into two groups and sit facing one another on either side of the choir area in the “choir stalls”. In cathedrals the singers on the left (when facing the altar) are called “cantoris” and those on the right are called “decani” (pronounce: dee-CAY-nye).
