Pérotin
French composer

Pérotin (fl. c. 1200) was a composer associated with the Notre Dame school of polyphony in Paris and the broader ars antiqua musical style of high medieval music. He is credited with developing the polyphonic practices of his predecessor Léonin, with the introduction of three and four-part harmonies.
Other than a brief mention by music theorist Johannes de Garlandia in his De Mensurabili Musica, virtually all information on Pérotin's life comes from Anonymous IV, a pseudonymous English student who probably studied in Paris. Anonymous IV names seven titles from a Magnus Liber—including Viderunt omnes, Sederunt principes and Alleluia Nativitas—that have been identified with surviving works and gives him the title Magister Perotinus (Pérotinus the Master), meaning he was licensed to teach. It is assumed that Perotinus was French and named Pérotin, a diminutive of Peter, but attempts to match him with persons in contemporary documents remain speculative.
Identity and career
Pérotin, about whom little is known, most likely lived around the end of the 12th and beginning of the 13th century and is presumed to have been French. The closest thing to a contemporary account of his life comes from two much later reporters: a brief mention attributed to the music theorist Johannes de Garlandia (fl. c. 1270–1320) in his De Mensurabili Musica, and four mentions in the works of a late 13c English student known as Anonymous IV. At one stage Anonymous IV was thought to be a pupil of Johannes de Garlandia, but this is unlikely, and the name is a misnomer, derived from the title of notes by Charles-Edmond-Henri de Coussemaker, Anonymus IV. These were probably notes taken by the student in a lecture. including this paragraph:
These rules were used in many older books; this was so during and after the time of Perotinus the Great. Nevertheless, they did not know how to distinguish these notes from those which will be presented shortly. This was so even since the time of Leo, because two ligated notes were put for the durational value of a brevis longa, and in a similar manner, three ligated notes were quite often used for a longa brevis, longa.
This brief starts where responsible research should: with the source description of “Pérotin” as french composer. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the people & ideas register because the source frames it as french composer. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Chronology provides the most reliable spine for this subject; interpretation should follow only after identities and dates are secure. The source revision retrieved here is dated Aug 4, 2026. The linked authority identifier is Q206275. VIAF identifies the subject as 222955753. The Library of Congress control number is n85327521. 3 of 9 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 1200, 1270 and 1320.
Public reputation and documentary evidence do not always develop together; absence from a summary is not evidence of historical absence. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
