"I love classical music," Chua says. "But for my own relaxation, I listen to country music. That's what's on my radio."She also mentions that the reason her children (and by her "rules" all children) can only play violin and piano is that those are the instruments she played. Played is the key word here. She obviously didn't continue playing into adulthood. Perhaps she didn't see the point.
Providing the necessary environment for a person to connect music (any kind of music) with true self-expression is the mark, in my opinion, of a successful music-oriented parent or set of parents. I guess the Tiger Mother's use of country music radio stations for relaxation shows what being raised in a pressure cooker can do for the soul.
