I read in the newspaper about a film of deaf people singing Bach. They rehearsed like a real choir and were accompanied by real musicians.
I don't know if I would want to see this film. The sound was described as ultra modern, as clear a condemnation of modernism as I've ever heard.
The idea raises questions for contemplation. Is this the inner Bach? The zen of Bach? For the deaf singers it was a wonderful event. Is it still Bach if you can't actually hear it? I say yes.
