Remembrance is constitutive of music. For music emerges not as an isolated physical stimulus. Rather, it is experienced, i.e., a present musical moment is tied to its temporal antecedents. It is tempting to conceive of remembrance as repetition and as thus opposed to oblivion. Yet to memory selectivity is crucial. What is not selected, falls into oblivion. Hence as we remember we have forgotten already. The present moment evokes remembrance, and exhibits what was then in the light of what is now. Remembrance changes the past it recovers. Listening to music, we may experience anamnesis to be metamorphosis.
