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.

Note that the melody is no more to be imagined as a specific sound than it is to be played: nothing tells us that the melody is to be heard as vocal or instrumental. This melody, however, is embodied in the upper and lower parts as a kind of after-resonance-out of phase, delicate, and shadowy.

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.
