Treatise On Harmony <LEGIT>

: Rameau argued that every chord has a "root" or fundamental note, regardless of which note is in the bass. This allowed for the identification of a core harmonic identity.

: Introduces the practical application of his theories, explaining the fundamental bass, modes, and the rules governing chords. Treatise on Harmony

: He established the "natural" relationship between chords, particularly the movement between the tonic and the dominant , which remains the backbone of most Western music today. Structural Breakdown : Rameau argued that every chord has a

The (originally Traité de l'harmonie réduite à ses principes naturels ) is a monumental 1722 work by French composer and theorist Jean-Philippe Rameau . Often cited as the foundation of modern Western music theory, it shifted the focus of music from horizontal melody to vertical harmony , establishing the mathematical and functional rules for tonality. Core Theoretical Contributions

The treatise is divided into four distinct books that move from abstract math to practical performance:

: Explores the physics of sound, focusing on string ratios, intervals, and the derivation of chords from a single "source" sound.
