I googled it, but how was I supposed to know about the Desna shrine + Harp + Sextan thing?

So I completed the puzzle, all is good, but I'm really curious about how I was supposed to learn about this in game? The shrine itself makes music, fine. But nothing points to Desna about it? How am I supposed to link this to the song from my previous quest (and play it from memory!). And as if that wasn't enough, how am I supposed to know to stuff a sextan and a small harp in the shrine? I'm sure it matches the lore, but from a player's perspective, that seems pretty random.

Most/all other puzzles in the game are fairly obvious, there are hints/instructions around on notes or walls and stuff. But this one was just "huh?"... google saved me, but I'm curious about whether there was a legit in-game way of learning about this.

Read description of item.
"A sextant engraved with a butterfly - symbol of Desna. If you listen closely you can just make out melody coming from it."

That with 3 similiar items and Shrine of Desna, and 1 item being already in shrine which gives off melody, should be enough.

Fair enough. Thanks for the pointer.

As for the remembering the song bit that seems a common theme that you have problems to solve based on detailed memories of something you see elsewhere.

Picture colours in the initial maze, order of images on wall for status in grey garrison, etc.

I think it is poor game design as you can't even consult the maps to find the clues.
