The madrigal.
Secular music genres such as madrigals and chansons were popular during the Renaissance period. Madrigals were particularly favored for their expressive and emotional content, evolving into a sophisticated form of vocal music characterized by intricate harmonies and texts inspired by poetry.
In the Medieval times the motet was a secular polyphonic vocal genre. Later on in the Renaissance time it became a sacred or devotional polyphonic vocal genre.
Two secular writers of the Renaissance were NiccolΓ² Machiavelli, known for his political treatise "The Prince," and Michel de Montaigne, known for popularizing the essay as a literary genre with his work "Essays."
