Note 20 — V FRÉDÉRIC CHOPIN

Bach's "Well-tempered Clavichord" is an example of a work to which, since its beauty is largely one of line, the piano cannot do justice. See, for instance, Prelude IV, in C-sharp minor, in the first book, measures 4-7, inclusive. The tenor part, of a wonderful nobility, is concealed by the more rapidly moving, and therefore on the piano more sonorous, soprano. In order fully to bring it to our consciousness we must sing or otherwise reinforce it.
