MRM Music

A cappella is vocal music performed without instrumental accompaniment, by soloists or ensembles. The term, Italian for “in the manner of the chapel,” originally distinguished Renaissance polyphonic practice from Baroque concertato styles where instruments often doubled voices. Over the 19th century—amid a revival of Renaissance polyphony and a mistaken assumption that such music was always sung unaccompanied—the term solidified to mean any unaccompanied vocal performance. Today a cappella spans sacred and secular idioms, from chant and polyphony to doo‑wop, vocal jazz, collegiate and professional pop groups, and contemporary styles featuring vocal percussion and microphone technique. Very rarely, the term has also been used as a synonym for alla breve (cut time), though this usage is uncommon in modern practice.
