What are Pan's Preludes "about"?

The answer is pure music, for the first three movements. The fourth is about Meesh. Or nostalgia about her. - As for the videos which I created for the Transtasia: I dunno: that was my subconscious mind, though I realise that the prevailing interpretation of the first movement is to do with the Christchurch Terrorist. Miniature = music school trauma. Across the Ocean = climate change.
