I keep thinking that when she's on Midgard at some point Siggy is introduced to the violin and just starts playing and loves it. probs just bc i listen to a lot of Lindsey Sterling. also that she plays instruments bc she's not comfortable with her singing voice
Sigyn don't need any instrument, her humming and whisteling would silence every bird around and bring them to listen to her like the most rarest of birds. She would steal every disney princess the show.
and then all the birds would go shit on everything in Loki’s room
