I have to practice, said my mother, and she went to the piano. The memory of her heavy arm, with the weighted hand stumbling over the keys, was still new. She put her hands on the keys and for an hour a terrible, jerking noise came from the front room. All of the children had played the piano attractively from the age of three; no Konigsberg had ever played a scale in living memory; my grandparents had never heard anything so horrible in all their lives.

My grandparents had previously thought that nothing could be worse than to hear Chopin’s Prelude No. 24 in D minor 30 times a day. They now thought they should have known when they were lucky. My grandmother went so far as to say Why don’t you play that lovely piece you were playing the other day, Linda?
