None of Chopin's contemporaries could rival him for the variety and effectiveness of his treatment of the return. - Charles Rosen

Meyerbeer's approach to opera may seem cynical. His music is not, like Donizetti's, an immediate expression of the sentiments of his characters but a calculated manipulation of the audience.

The relation of tonic to dominant is the foundation of Western triadic tonality. The attempt of the early nineteenth century to substitute third or mediant relationships for the classical dominant amounted to a frontal attack on the principles of tonality, and it eventually contributed to the ruin of triadic tonality. This ruin was accomplished from within the system, however, as mediant relationships were essential to tonality as conceived in the eighteenth century.

There is a paradox at the heart of Chopin's style, in its unlikely combination of a rich chromatic web of polyphony, based on a profound experience of J. S. Bach, with a sense of melody and a way of sustaining the melodic line derived directly from Italian opera. The paradox is only apparent, and it is never felt as such when one hears the music. The two influences are perfectly synthesized, and they give each other a new kind of power.
