A choir is a musical ensemble of singers. Choral music, in turn, is the music written for such an ensemble to perform. Choirs may perform music from the classical music repertoire, which spans from the medieval era to the present, or popular music repertoire. Most choirs are led by a conductor, who leads the performances with face gestures. A body of singers who perform together as a group is called a chorus; the former term is often applied to groups affiliated with a church and the second to groups that perform in theatres or concert halls, but this distinction is far from rigid. Choirs may sing without instrumental accompaniment, with the accompaniment of a piano or pipe organ, with a small ensemble, or with a full orchestra of 70 to 100 musicians; the term choir has the secondary definition of a subset of an ensemble. In typical 18th- to 21st-century oratorios and masses, chorus or choir is understood to imply more than one singer per part, in contrast to the quartet of soloists featured in these works.

Choirs are led by a conductor or choirmaster. Most choirs consist of four sections intended to sing in four part harmony, but there is no limit to the number of possible parts as long as there is a singer available to sing the part: Thomas Tallis wrote a 40-part motet entitled Spem in alium, for eight choirs of five parts each. Other than four, the most common number of parts are three, five and eight. Choirs can sing without instrumental accompaniment. Singing without accompaniment is called a cappella singing. Accompanying instruments vary from only one instrument to a full orchestra of 70 to 100 musicians. Many choirs perform in many locations such as a church, opera house, or school hall. In some cases choirs join up to become one "mass" choir. In this case they provide a series of songs or musical works to celebrate and provide entertainment to others. Conducting is the art of directing a musical performance, such as a choral concert, by way of visible gestures with the hands, arms and head.

The primary duties of the conductor or choirmaster are to unify performers, set the tempo, execute clear preparations and beats, to listen critically and shape the sound of the ensemble. The conductor or choral director stands on a raised platform and he or she may or may not use a baton. In the 2010s, most conductors do not play an instrument when conducting, although in earlier periods of classical music history, leading an ensemble while playing an instrument was common. In Baroque music from the 1600s to the 1750s, conductors performing in the 2010s may lead an ensemble while playing a harpsichord or the violin. Conducting while playing a piano may be done with musical theatre pit orchestras. Communication is non-verbal during a performance. However, in rehearsals, the conductor will give verbal instructions to the ensemble, since they also serve as an artistic director who crafts the ensemble's interpretation of the music. Conductors act as guides to the choirs they conduct, they choose the works to be performed and study their scores, to which they may make certain adjustments, work out their interpretation, relay their vision to the singers.

Choral conductors may have to conduct instrumental ensembles such as orchestras if the choir is singing a piece for choir and orchestra. They may attend to organizational matters, such as scheduling rehearsals, planning a concert season, hearing auditions, promoting their ensemble in the media. Most Eastern Orthodox Christian churches, some American Protestant groups, traditional Jewish synagogues do not accompany their songs with musical instruments. In churches of the Western Rite the accompanying instrument is 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, Roman Catholic Churches may use, at their discretion, additional orchestral accompaniment. In addition to leading of singing in which the congregation participates, such as hymns and service music, some church choirs sing full liturgies, including propers. Chief among these are the Roman Catholic churches.
