A motet is a type of vocal music that originated in the medieval period, typically featuring multiple independent melodies sung simultaneously. It often includes sacred texts and is performed a cappella, meaning without instrumental accompaniment. Motets were popular during the Renaissance, showcasing complex harmonies and intricate counterpoint. Motets can vary in style and structure, with some being based on pre-existing melodies or chants, known as Gregorian chant. Composers like Josquin des Prez and Palestrina are well-known for their contributions to the motet genre, which remains an important part of choral repertoire today.
