It's never been my subject, but people do study music like that.
I did notice it featured heavily. Do you have written music, or would that be a new idea too?
Like, I said, not my subject, but when Asgardians do it, it looks approximately like - And she sends a picture of sheet music, notes and lyrics, mentally annotated.
Not everything, to capture everything you need a sound recording and those are unpopular on Asgard because they can't be made to seem low-tech, but it'll do notes and rhythm and tempo and dynamics with other marks here and there about what else should be kept in mind while performing it.
And then you could trade songs with other people, if they learned to do it too.
I imagine that takes a while, to go through a large repertoire well enough that the songs get learned, but I suppose that's not such a deterrent for Quendi...
It's definitely an enduringly popular medium for joy. Less so news and history.
I'd hope so. I wasn't imagining the disappointment would be fatal. Gardens? Gardens. Food.
