Imitative polyphony is vocal style that features overlapping entrances from voices that imitate the melodies of the other singers.

Explanation:

During the Renaissance period, which spanned roughly from 1450-1600, polyphony was a style that was widely used in the music of the times. This was in contrast to previous styles of music seen in the Middle Ages, where the vocal style was usually in the form of a single line of melody sung by all voices and with little variation. Polyphony can be imitative or non-imitative. The imitative style was especially popular in Western European music during the later Renaissance and the Baroque periods.
