A cappella is vocal music performed without instrumental accompaniment. The term comes from Italian and literally means “in the style of the chapel”, referring to the tradition of unaccompanied church singing.
What does a cappella mean?
Originally, a cappella described sacred choral music performed without instruments. Today, the term covers a wide range of musical styles, from classical choirs to modern vocal groups, barbershop quartets and contemporary a cappella ensembles.
Because there are no instruments to support the singers, a cappella performances require excellent intonation, accurate pitch and the ability to maintain a steady musical key throughout the performance.
How is a cappella used in piano playing?
Although a cappella music is performed without instruments, the piano often plays an important role during rehearsals. A pianist may act as an accompanist or rehearsal pianist, helping singers learn their individual parts and check their pitch.
Before a performance, the starting note is often given discreetly on a piano or with a tuning fork so that the singers begin in the correct key.
