Léonin was the first known composer of polyphonic organum and was the leading liturgical composer of his generation who flourished in the 12th century and is associated with the Notre Dame or Parisian school of composition.
It is with Léonin that we begin our journey through the history of western music with its origins located firmly in the medieval period.
The Magnus Liber Organi (Great Book of Organum c.1170) is attributed to him by a source known as Anonymous IV. .
The piece I’m focusing on this week is his Messe du jour de Noël (Christmas Day Mass).
Enjoy!
