Music performed a cappella, less commonly spelled a capella in English, is music performed by a singer or a singing group without instrumental accompaniment. The term a cappella was originally intended to differentiate between Renaissance polyphony and Baroque concertato musical styles. In the 19th century, a renewed interest in Renaissance polyphony, coupled with an ignorance of the fact that vocal parts were often doubled by instrumentalists, led to the term coming to mean unaccompanied vocal music. The term is also used, rarely, as a synonym for alla breve.
Collegiate a cappella ensembles are college-affiliated singing groups, primarily in the United States, and, increasingly, the United Kingdom and Ireland, that perform entirely without musical instruments. The groups are typically composed of, operated by, and directed by students. In the context of collegiate a cappella, the term a cappella typically also refers to the music genre performed by pop-centric student singing groups. Consequently, an ensemble that sings unaccompanied classical music may not be considered an a cappella group, even though technically it is performing a cappella.
