Making music has some interesting similarities to writing fiction.
Particularly: "Where do your ideas come from?"
Honestly it's as if they came straight from the aether without preamble or consideration. You can sense the imminence of it all, the crackle of electricity in the air.
You pick up the guitar or open the notebook. The page is still blank, the notes are still hidden. But they are right there, waiting.
The shiver of purpose and meaning gaining momentum like a pressure from the air around you and suddenly you make something like this.
