- 1861, William Howitt, John Cassell's illustrated history of England:
  Church music was carefully taught at the universities. IT was of the four sciences of the quadrium, and was a means of promotion in the church and colleges.
- 1997, Timothy J. Reiss, Knowledge, Discovery and Imagination in Early Modern Europe:
  He describes how by the late fifteenth century the language arts of the trivium had come to seem useful only for communication, teaching and public debate, and how humanists turned to the mathematical arts of the quadrium - including music - to enable new means and methods of discovery.
- 2014, Andreas Nordin, Transnational Policy Flows in European Education:
  The classical curriculum distinguishes between trivium and quadrium to classify knowledge fields in education. Trivium deals with the disciplines of language, grammar, rhetoric, dialectic and logic, while quadrium deals with the sciences of arithmetic, geometry and astronomy.
