THE FIFTH OF Bach’s three-part inventions was labeled BWV 791 by scholars and was one of the hardest in the canon, but it was Rita Scimeca’s favorite piece in all the world. It depended entirely on tone, which came from the mind, down through the shoulders and the arms and the hands and the fingers. The tone had to be whimsical, but confident. The whole piece was a confection of nonsense, and the tone had to confess to that, but simultaneously it had to sound utterly serious for the effect to develop properly. It had to sound polished, but insane. Secretly, she was sure Bach was crazy.
