This girl was 13 at the time. She did not major in piano but trombone and now plays for symphonies. Her father was a conductor. She said that her biggest problem was when playing with symphonies it would drive her nuts when the symphony would tune sharp of the standardized tuning of 440 because to her ear 440 was normal. When she was young and would hang out with my daughter, she would identify the pitches of all the different sounds like printers transformer noise etc. Got to be a joke after awhile.
