When Midori was two years old, she often climbed onto the piano bench and reached for the violin that belonged to her mother, a 30-year-old professional musician. "Please don’t touch, Midori," her mother scolded. The violin was, after all, worth more than $20,000. But Midori persisted. She longed to handle the graceful instrument that made beautiful sounds. Finally, on her third birthday, Midori was handed a package, a tiny violin, about half the normal size.
    Almost from the moment Midori was born, her mother knew she was sensitive to music. For several years mother and daughter practiced together day after day. She was eager to learn. Failure often led to tears, though she never once turned from the instrument Instead, she persisted until the problem was overcome.
    One day Johnson, an American musician, heard Midori playing the violin. He couldn’t believe she was just eight years old. "She must make a tape and I will take it to the United States." the American musician said. A famous American violin teacher heard the tape. He, too, had difficulty believing his ears. The playing was absolutely astonishing.[15]He immediately accepted her as a pupil and recommended her for a full scholarship. Thus in 1982, Midori and her mother moved to New York City, leaving behind a comfortable life in Japan.
