medieval music notation

Modal Notation

6 sessions - Self-paced

Course Description

Towards the end of the twelfth century a composer known as Leoninus, canon of the Cathedral of Notre Dame in Paris, created a whole cycle of polyphonic settings (organum) for chants of the Mass and Office which was eventually called the Magnus liber organi. Thanks to his successor Perotinus, this repertoire was progressively enlarged to the extent that its four extant manuscripts include not only organa, but also clausulaeconducti and motets. This music was characterized by the use of certain rhythmic patterns called ‘modes’, which led to the development of one specific type of script: Modal Notation. For the first time in the medieval West, it was possible to record rhythmic durations. The new notation prompted the creation of progressively more complex polyphonic compositions. In practical terms, Modal Notation is the key to the vast repertoire of music associated to what is known as the School of Notre Dame.

In this course, students will:


Study the different genres, manuscripts and theoretical treatises that record the theory and practice of Modal Notation


Apply the precepts of Modal Notation to actual polyphonic compositions of the era


Transcribe polyphonic pieces of the repertoire


Sight-read and perform different compositions directly from the original sources
