To play devils advocate: if I were in a competition jury and a competitor did a radically different interpretation (a la Gould) of a hacked-to-death piece, it would seriously interest me.
TThe problem is not that music is open to a diversity of interpretive possibilities. The problem is that certain adjudicators think that their interpretation is the only one that carries validity.
Should we start calling you Martha?
Music is a subjective art, but it isn't as subjective all the time as you might think!
One cannot simply play badly and claim that this is his or her valid interpretation of a certain piece, and yet many amateurs do that frequently!
Why would one consider the status of the performer, professional or amateur, in the evaluation of an interpretation?
I don't get it. Is this what happens if one stays away from PS for a few days?
