Charles Rosen Quote

Technical display in Chopin, after the early works, is transmuted into tone color or dramatic gesture-we may say, to accept the prejudices of Chopin's own generation, that it has been ennobled. This is the source of much of the poetry in Chopin's music: it comes from the transformation of the vulgar into something aristocratic.
