Perotin (composer)

Perotin was a medieval composer known for his pioneering work in polyphony, the simultaneous combination of different musical lines. Active around the late 12th to early 13th centuries, he is associated with the Notre Dame school of music in Paris. Perotin expanded on earlier vocal styles by introducing intricate layers of melody, creating rich harmonies. His most famous works include "Viderunt omnes" and "Sederunt principes," which showcased these innovations. Perotin's contributions helped shape the development of Western music, moving it toward more complex forms that would influence future composers.
