Pérotin

Pérotin was a medieval composer from the late 12th century, renowned for creating intricate and innovative organum—early forms of polyphonic music involving multiple melodic lines sung simultaneously. Working in the Notre Dame School in Paris, he expanded musical complexity by adding voices and developing new techniques for harmonizing melodies. His work marked a significant advancement in Western music, laying the foundation for the development of more complex choral compositions. Pérotin's compositions are valued for their pioneering role in shaping sacred music during the Middle Ages.
