A Cappella Has Italian Roots

A cappella arrived in English in the 18th century via the Italian phrase a cappella, meaning "in chapel or choir style." (Medieval Latin capella, meaning "chapel," is the source of English chapel.) The a cappella style reached preeminence in the late 16th century in the music that composer Giovanni Pierluigi da Palestrina wrote for the Sistine Chapel of the Vatican. Because no independent instrumental parts were written down, scholars once thought that the choir sang unaccompanied, but current evidence makes clear that an organ or other instruments doubled some or several of the vocal parts. Regardless, today a cappella describes a purely vocal performance.
