We can, in fact, relive the history of taste in our own lives, the way embryos are supposed to go through the history of the evolution of a species. - Charles Rosen

Chopin is the true inventor of the concert etude, at least in the sense of being the first to give it complete artistic form—a form in which musical substance and technical difficulty coincide.

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.

It is fitting that a discourse on Romantic music should commence with a meditation on the art of Bach. The Bach revival is still sometimes considered an early nineteenth-century phenomenon, although this is hardly tenable: in the 1780s Mozart was deeply affected by Bach, and at the same time Beethoven was being brought up on the Well-Tempered Keyboard. Bach was well known to European musicians as a composer of keyboard music through manuscript copies of this work long before systematic publication began in 1800. The "revival" of Bach in the Romantic period was basically a rediscovery of his choral works and a new evaluation of his technique: his art was no longer simply a model for the fugue, as it had been in the eyes of Mozart, but for the art of music as a whole. The new approach to Bach and to Baroque music in general, however, did not extend to the sound of that music on the original instruments. Few musicians in the 1820s and '30s 'had the slightest interest in the sonority of old harpsichords or Baroque organs (Ignaz Moscheles was an engaging exception). What they saw, and needed to see, in Bach was the achievement of an ideal.
