An old instrument

My house has an old instrument. It's called clavichord and it was made in Germany in 1681.

Our clavichord is in the living room.
We have had this instrument for a long time, it was bought by my grandfather from years ago.
But recently it was damaged by a customer, because she used it to play jazz music.
She struck the keys too hard and two strings were damaged.
My father was very shock, he doesnt want us to touch it.
My father's friend is going to try to repair this instrument for us.

Notes

It isn't clear to me if he customer broke two strings by pressing one key or multiple keys. According to wikipedia, clavichord construction varies. If it was a single key, feel free to revert "keys" to "key".

Good work!
