Démonstration du principe de l'harmonie : servant de base à tout l'art musical théorique et pratique - Rameau, Jean-Philippe 1683-1764 (Paris Durand Pissot, 1750)
"Though Rameau had already stated the fundamental principles of his revolutionary theory of harmony in his 'Traité de l'harmonie' of 1722, he continued to revise and adapt the new system until his death some forty years later. In 'Demonstration', Rameau offered a new derivation of the minor third (based upon a theory of multiple generation), and "altered his view of the subdominant [recognizing] its position as a product of musical experience rather than of nature" (GDM). Rameau submitted 'Demonstration' to the Academie Royale des Sciences, which gave the work its approval." (from an inserted note printed on paper from John Howell - Books San Francisco)
