Inexpressivity

The critics also would discover an individual structure in the score: a singular, artful alternation of the savage in mood and movement and the dreamy and exalted; a juxtaposition of heavy march-rhythms and dragging or ecstatic rhythms; and abrupt juxtapositions of inexpressivity and extreme expressivity.

By demonstrating, even on this superficial level, that it is possible to cry without having pain the degree of emotional inexpressivity is lessened.

Particularly ingenious, I think, is the bilingualism: the English “notes-art” implying the pianist’s inexpressivity, and the German “no-zart” (zart meaning tender or delicate).
