.. Amber Orb

Hans saved you. He said the Weisse Frauen are different around music.

A band was playing earlier with a wooden stringed instrument to them.

There are the musicians.

Help them to their house. I'm sure they will appreciate your help. ( After getting them into the house go knock the door, again. )

You got an instrument from them. Maybe you have to do the playing. Go play the violin to Weisse Frauen.

Is it the musician or the instrument?

You could find a better violin.

In the store. Get the better violin from there.

Go play to the Weisse Frauen with the magical violin.
