==History==

A cappella became a preeminent style in the late 16th century, as it was the preferred style of the choir of the [[Sistine Chapel]].  It is possible that the allegedly impure a cappella appeared during this time, as it was a tendency of churches to accompany their singers using church organs.  By the 17th century, the a cappella genre was giving way to the [[cantata]].
