Sonority Quotes

In f-major, c* [a C major chord] is a sonority contained within the overtones of the tonic f. (Jean-Philippe Rameau)
The opposition between structure and sonority in music is almost as misleading as that between line and color in the visual arts. Baudelaire insisted, correctly, that Delacroix was one of the three greatest draftsmen of the century, and emphasized his mastery of line. In the same way, a study of Chopin demonstrates the intimate relation between line and color in music. View quote

For Beethoven, music was still shape, realized and inflected by instrumental sonority: other realizations may be as absurd as arrangements of the Hammerklavier, for example, always are, but the musical conception takes precedence over its realization in sound. The sonority serves the music. For Schumann, however, as for Chopin and Liszt, the conception was worked out directly within the sonority as a sculptor works directly in clay or marble. The instrumental sound is shaped into music. View quote

The piano is the only keyboard instrument in which one can grandly vary the effects of the harmonics or overtones of a chord at will by balancing the sonority in different ways. View quote

In the piano writing of the Romantic generation of the 1830s, in fact, a fully pedalled sonority becomes the norm: the piano is expected to vibrate fairly constantly, and an unpedalled sonority is an exception, almost a special effect. Furthermore, the phrase is now shaped at least partially by changes in this full vibration. The change of pedal is crucial to the conception of rhythmic movement and to the sustaining of the melodic line over the bass. View quote
