description Léonin Overview

Léonin (active c. 1150s–1201) was a composer at the Cathedral of Notre Dame in Paris and is credited, with Pérotin, with developing the polyphonic organum associated with the Notre-Dame school. His work is documented in the anonymous treatise "Magnus Liber Organi," a collection of graduals, alleluias, and responsories for the liturgical year. The style expanded existing chant by adding a second voice, creating elaborate melismatic lines above the tenor.

Later tradition identifies him as Magister Leoninus.
