Research title: A modern study of Thirteenth–century Organa and Motet

Research Summary

PhD project

Thesis title: What is a clausula?

Discovering a tighter set of parameters that define a thirteenth-century clausula:

  1. What is a clausula, exactly? Definitions of clausulae are wide-ranging in modern writing.
  2. To what extent can the clausula be conceived of as the atom of thirteenth-century polyphony in organa and motet, and what modern methodologies can we apply to this question.

I am conducting a survey of the notational content in the sources of thirteenth-century polyphony. My research methodologies are focused upon:

  • Digital humanities
  • MEI
  • OMR / Machine Learning
  • Accessible web technology as research output


iuchair is a medieval vocal ensemble based in Glasgow, brought together by a shared interest in medieval music, particularly that of neglected, unusual and seldom–performed repertories. Always performing from bespoke editions, iuchair put particular emphasis on bringing performance of early music up to date with current academic thinking by dispelling myths of early music performance, starting again from scratch in matters of pitch, tuning and tempo, considering at the foremost how the music can be best performed.
