A mouse called wolf

Wolfgang Amadeus Mouse ("Wolf," for short) has a big name to make up for his small size. But the name fits. While his siblings like to race each other across the black and white piano keys, he would rather listen to Mrs. Honeybee the lady of the house, play music on them. Then one day, in a moment of musical passion, Wolf throws his head back, and to his total surprise, out of his mouth comes a beautiful voice!.
