A precentor is one who helps facilitate worship. The details vary depending on the religion, denomination, and era in question. Its Latin meaning is "the one who sings before" (or alternatively, "first singer").
The chief precentor was the highest position in many ancient Mesopotamian cities (see Music of Mesopotamia).
Jewish precentors are song or prayer leaders, leading Synagogue music. This is attested to at least as early as 30 AD, and continuing to the present day.
A precentor is a member of a church who helps facilitate worship. The role of precentor was carried over from the synagogues into the early church.
In the cathedrals of England, France, Spain, and Germany, he ranked sometimes next to the dean, sometimes next to the archdeacon. In some instances his sphere of activity was much broader, including the duty of installing deans, canons, and other dignitaries; and in some monasteries, the duties of librarian and registrar. But from the fourteenth century his title and dignity were largely handed over to incumbents whose musical knowledge did not fit them for the duties to which the name of precentor owed its origin; the dignities remained, but the duties became obscured. "In France, some chapters retain traces of the dignity of Precentor, and one may see sometimes an archdeacon, sometimes a titular or honorary canon, carrying the baton cantoral, the insignia of his office. This "baton cantoral" is a silver or white staff. "In the dioceses of Aix, Carcassonne, Coutances, Dijon, Metz, Orléans, the dignity of Precentor is still the highest in the chapter.... Some chapters have sub-chanters, those of Arras being among the honorary resident canons, where also the quoted statutes of the Bishop of Dijon may serve to illustrate the modern idea of the office of precentor: "The Précenteur or Grand Chantre is the head of the choir and ... brings the antiphon to the bishop when officiating pontifically. Sacristans, chanters, choir-boys, and employés of the Cathedral are placed under his surveillance. He will also preserve order and silence in the sacristy").
A precentor is a person, usually a clergy member, who is in charge of preparing worship services. This position is usually held in a large church, and is typically used in the churches of the Anglican Communion. Most cathedrals have a precentor in charge of the organisation of liturgy and worship. 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 than that of the Dean, leading to the traditional division of the singers into Decani (the Dean's side) and Cantoris (the precentor's side).
In Presbyterian churches that worship in the historical fashion (ie. sing A cappella; see Presbyterian worship), a precentor is a person (man or woman, not necessarily clergy) who leads the singing, often by means of conducting techniques, but sometimes just by singing from amongst the congregation.
Churches that used a repeat-after-me manner of singing called lining out (used primarily when sufficient numbers of psalm books were unavailable, or the congregation insufficiently literate, as was the case in the black church in Harper Lee's To Kill a Mockingbird) would usually be led by the precentor, much as with other non-instrumental churches.
