No, it is actually an opera.
It's not Norma (is that a character or the title of a work? I'm not familiar with it).

damn, then it's gonna be hard for me XD

Actually I think it's both the title and the character's name I think....

Okay, so maybe from the Magic Flute?

Yes :) So now the character is obvious, isn't she?

So it's the Queen of the Night? (Is that her official name? I've never seen/watched/heard the Magic Flute )

Yes, that is her name :)
Congratulations, you figured it out without even knowing the source then!

Yay me! *confetti rain* So modest am I, right? XD
I just googled operas with witches, then got some opera blog with the best opera witches (or something like that) and that's one of the few on that list

Could have never guessed Opera, it´s not my type of interest.^^

But funny idea.

Mem, you're allowed to celebrate yourself a little when you solve a riddle ;) Also, confetti ;)

Yeah, I was wondering if anyone would think of it :D

I thought of opera the second I noticed the notes and the mouth Then read the guessing part and noticed the "more than a song" and opera was the first thing that came to mind

I love to use the banshee mouths to depict singing :)
I tried to capture the aria where she gives a dagger to her daughter and tries to make her murder someone.
