From Ars Nova to the Renaissance: How Notation Changed Music
Rhythm took two centuries longer than pitch to notate. Mensural notation solved it with ratios, and the Renaissance then replaced black ink with white.

Repertoire, notation and practice from the medieval period to the present, told through the documents.
Music history told through documents and practice: how notation changed what could be written down, how continuo and the bass line produced functional tonality, how Romantic chromaticism expanded the tonal frame without leaving it, and what composers did when the frame finally broke.
Rhythm took two centuries longer than pitch to notate. Mensural notation solved it with ratios, and the Renaissance then replaced black ink with white.
When chromatic harmony outgrew the tonal hierarchy, composers tried serial rules, rhythm, folk modes, and sound mass. What each method actually solved.
Around 1600 the bass became the foundation of harmony and the modal system narrowed to two keys. What changed in the documents, and what the change cost.
Chromatic harmony widened a key without leaving it: the resources that do the work, the Tristan chord, and how to analyse it without over-labelling.
