Anxiety for Heidegger is the mood that first reveals the self. It’s the mood where the self is first precipitated, precipitated against the world. The world as it were drops away, slips away. What’s revealed is me, but not me as some substance, rather me as a nothing — a me that is a kind of mood of anxiety or boredom or a bundle of neurons or whatever it might be. That’s the zone that music speaks to. That’s the claim I’d like to make, as strange as it seems.
