i'm not sure if this song has a title, but i would love if there was sheet music made for this little theme.
Sounds like this:

Actually, I think it's one of the other "ambient" themes. Maybe this one?
Sorry, the constant scrolling is driving me insane so I'm not actually gonna check the whole thing >_> (it does segue into BoTW's Main Theme later though)
This is my 3DS theme and I can confirm, Latios has the right one.
I recently just transcribed this piece. On the official Breath of the Wild soundtrack it is simply called "Ruins". Once a sheet of mine gets approved I will post this one on the submission forum :D
I actually also have a finished sheet of this, believe it or not. I'm totally fine if Sidon wants to submit his arrangement, though.
