 The precentor of a cathedral is usually a residentiary canon or prebendary and may be assisted by a succentor (particularly in the daily task of leading choral singing).In some cathedrals (including Canterbury), the precentor is a minor canon and therefore part of the foundation but not part of the chapter.Traditionally the precentor's stall (seat) in the cathedral is on the opposite side of the quire from that of the dean, leading to the traditional division of the singers into decani (the dean's side) and cantoris (the precentor's side).
