A young girl sits at the piano in a music store and plays for a customer the latest hit "Just a Kiss". A young man comes in the store, listens, asks what it is and then says: "The original sounds better!" And then he plays on his violin Mozart's D major minuet for violin. The girl in the shop is Inga, daughter of the instrument maker and violin maker Lars Bergius. Like her father, she prefers classical music. But she has a brother, Macce, who loves swing and is the leader of a jazz band.
