I suppose I was misremembering your use of "evocation" in connection with music: you wer opposing evocation to representation.

One thing I have not cogitated so broadly is music and how we find the meaning in sound. I don't know enough about the physiological processes. The interesting thing about music though is that it doesn't exist in 'real life', in the same way that you can compare a portrait (of a living person) with the real person, or look at sunflowers in the garden and then look at van Goghs 'Sunflowers'. All music is a construct - it doesn't refer to anything that exists in Nature, it refers only to our musical experience. It is pure evocation.

Anyway, at best instrumental music gives me shivers.
