Jean-Philippe Rameau’s Traité de l’harmonie (1722) develops a theory of harmony, then applies it to composition and accompaniment. Its terminology and rules belong to the musical practice of its time.
Start with a short passage and one example. Choose Simplified English, English, or Caveman for different levels of language, and switch to French to compare the original wording.
