Wunderkind (1981)

The child is still in the baby cot, but Mom and Dad want to make him a great musician. They bring a violinist teacher to the child. The child shoots him with a violin, like a bow. The next teacher is a pianist. Both he and the piano run away from the child. In front of the teacher-singer, the child screams like an Indian. He even breaks the baby's cot. When the carpenter comes to fix it, the child calms down for the first time and helps the master.
