Pérotin was a European composer, believed to be French, who lived around the end of the twelfth and beginning of the thirteenth century. He was the most famous member of the Notre Dame school of polyphony.

Pérotin's works are preserved in the Magnus Liber , the "Great Book" of early polyphonic church music, which was in the collection of the cathedral of Notre Dame in Paris. The Magnus Liber also contains the works of his slightly earlier contemporary Léonin. However, attempts by scholars to place Pérotin at Notre Dame have been inconclusive, all evidence being circumstantial, and very little is known of his life. His dates of activity can be approximately established from some late 12th century edicts of the Bishop of Paris, Odo of Sully , which mention organum triplum and organum quadruplum , and his known collaboration with poet Philip the Chancellor , whose Beata viscera he could not have set before about 1220. The bishop's edicts are quite specific, and suggest that Pérotin's organum quadruplum Viderunt omnes was written for Christmas 1198, and his other organum quadruplum Sederunt Principes was composed for St. Stephen's Day (December 26), 1199), for the dedication of a new wing of the Notre Dame Cathedral. His music, as well as that of Léonin and their anonymous contemporaries, have been grouped together as the School of Notre Dame.

Perotin composed organum, the earliest type of polyphonic music; previous European music, such as Gregorian and other types of chant, had been monophonic. He pioneered the styles of organum triplum and organum quadruplum (three- and four-part polyphony); in fact his Sederunt principes and Viderunt omnes are among only a few organa quadrupla known. He was one of very few composers of his day whose name has been preserved, and can be reliably attached to individual compositions; this is due to the testimony of an anonymous English student at Notre Dame known as Anonymous IV, who wrote about him.

A prominent feature of his compositional style was to take a simple, well-known melody and stretch it out in time, so each syllable was hundreds of seconds long, and then use each of those held notes (the tenor, Latin for "holder", or cantus firmus) as the basis for rhythmically complex, interweaving lines above it. The result was that one or more vocal parts sang free, quickly moving lines ("discants ") over the chant below, which was extended to become a slowly shifting drone.

His music influenced modern "minimalist" composers such as Steve Reich, indeed, it can be argued that Perotin himself was a proto-minimalist. His works include the four-voice Viderunt omnes and Sederunt principes; the three-voice Alleluia, Posui adiutorium , Alleluia, Nativitas , and nine others attributed to him by contemporary scholars on stylistic grounds, all in the organum style; the two-voice Dum sigillum summi Patris , and the monophonic Beata viscera in the conductus style. (The conductus sets a rhymed Latin poem called a sequence to a repeated melody, much like a contemporary hymn.) Anonymous IV called him "Perotin Magister", which means Pérotin the master or expert.
