Chören
Chören is a German term used to denote choirs in contexts where the dative plural form is required; the nominative plural is Chöre. In general usage, the word refers to organized ensembles of singers that perform choral music under a conductor. Chören may range from small chamber groups to large professional ensembles, and they may be mixed, men's, or women's voices. Common types include church choirs, concert choirs, school or community choirs, and professional choruses.
A typical choir consists of voice parts—Soprane, Alt, Tenor, and Bass—though exact classifications vary by tradition.
Historically, choral singing has been central to church music and civic culture in many European traditions.
