In Norse mythology the völva(seeress) has trance while listening to music/singing/ritual.
In Scandinavian sources, seeresses work as diviners using a practice called seiðr on a ritual platform called seiðhjallr
There are two ways in which the seeress conveys the acquired information to the audience. One of them is by having a seizure during the trance and gasping for air with a wide open mouth (Hrólfs saga kraka and Hauks þáttr hábrókar). She delivers her prophesy during the trance, and it may be said that a song appears from elsewhere in her mouth (Ǫrvar-Odds saga and Hrólfs saga kraka).
Other names for the songs are varðlok(k)ur and seiðlæti, where the latter simply means "seiðr songs". The former term is more complex, and scholars such as Cleasby and Vigfússon, Tolley, Strömbäck and Price have derived it from vǫrðr ("guard, protector").[108][109][110][111] Several scholars have also compared it to the Scotting dialect word warlock,[111] and scholars such as Cleasby, Vigfússon and Strömbäck consider it to be the origin of the Scottish word.[112][109] Katherine Morris translates the word as "warlock-song"
The last two are connected to seidr magic in norse mythology. I talked about its connection to elain in here.
And I read a book about shaminism and old pagan rituals. Songs are connected with seers. Again seidr but it is a magic performed by a seer lol.
So ⚡ was meant for Hunt but at the end he "fueled" her up becoming a THEM thing
🎶 is now connected to Azriel but at the end will become as the OP said a them thing.
As the last ss suggests songs are a way for a seer to "see" basically. 🤷🏻♀️
And we should forget that gwydion tt cauldron ramiel stone all sing....which I talked about their connection here.
