to me, the qualities that spill on an artist's work without his/her being conscious of it are too significant to be disregarded or even treated as any less praiseworthy.
I think, at a subconscious level, I even desist associating various emotions to compositions.
And, being a purely abstract form of art, I think the role of nuNNuNarvu -- the intuitive 'leap' to challenge oneself -- is even greater in music.
but in a philosophical sense, this has never been the ‘artist's’ interest
As I see it, the idea that the reader doesn't have to depend on the author's intentions has nothing to do with it.
