MOZART
The composer whom we call WOLFGANG AMADEUS MOZART was called Wolferl when he was a little boy.
He had a sister, MARIA ANNA, who was called NANNERL.
Nannerl was five years older than her brother. She had lessons from her father on a kind of piano called a harpsichord.
Here is a picture of one.
MOZART'S HARPSICHORD
When Wolferl was three years old he used to listen to Nannerl's playing. He always watched and listened when Papa Mozart gave her a harpsichord lesson.
