I think it's plausible that a good pianist could perform fantastic music without putting any "soul" into it. That is, the audience could have a profound, moving experience, although, for the pianist, the activity is mechanical and repetitive, or even boring, unpleasant or tedious, because they've performed the same piece many times before. What I wanted to ask is -- if the audience learned what the pianist was really doing, would they be justified in thinking that their experience wasn't profound after all, or in feeling somehow cheated? Does it really matter whether or not the performer is themselves connected to the work?
