These are some of the questions that Christopher Norris addresses by way of a sustained critical engagement with the New Musicology and other debates in recent philosophy of music. His book puts the case for a qualified Platonist approach that would respect the relative autonomy of musical works as objects of more or less adequate understanding, appreciation, and evaluative judgement. At the same time this approach would leave room for listeners share the phenomenology of musical experience in so far as those works necessarily depend for their repeated realisation from one performance or audition to the next upon certain subjectively salient modalities of human perceptual and cognitive response.
