The trailer for the upcoming film Morbius uses segments of Beethoven's "Für Elise" mixed in with an epic score like you'd expect from a movie based in the Marvel universe. But what is the reason? Is there some kind of symbolism or significance of that song to the movie?
Because the main characters also humm the intro to "Für Elise", and only intro, I assume it have to do with the "Für Elise" creation story.
Beethoven wrote this piece for student of his that was terrible at playing piano. So that's why the beginning is easy. But later he learned that she was married/egnaged/had a boyfriend. So he made the rest of the piece so hard she couldn't play it.
So Morbius is humming the intro because things are easy. He work on the cure, he help some child. Then it get so hard he start killing people.
