About this playlist
Pérotin was a composer of the late 12th century who worked and taught at the Notre Dame Cathedral in Paris. Along with his predecessor, Léonin, Pérotin was a crucial figure in the development of medieval polyphony – ie. music with multiple parts at once. The compositions of his that we know of were all written down in a book at Notre Dame called the "Magnus Liber", or "Great Book", but he shared the book with his teacher and fellow polyphonal innovator Leonin, as well as the composers and teachers who followed, so we don't know for sure which compositions are his and which belong to others.
