i'm curious what happens in your mind when you hear music or sing something and you're thinking about the chords and melody and stuff. Do you see a keyboard with the notes you're hearing sort of being played or lighting up? That's kind of what happens for me except it's not neccassirly the right key because i don't have perfect pitch
probably see keys, but it's not necessarily always in the right key unless i really crawl into the depths of the absolute abyss and check. which is very uncomfortable but i always do it every time, with the determination of someone running from their past somehow
