Wow, a lot of slighted pro or semi-pro musicians in the comments, not a lot of hacker spirit. I didn't sense any competitiveness in this article at all, and author clearly described her embarrassment at being completely non-musical, and the desire for her kids to be at least not shut off completely from the musical world skill-wise. And she did it after being prompted by a very interesting question--why is "perfect pitch" considered so difficult for the human brain compared to distinguishing any color out of millions (well, we probably only have common words for a couple hundred), which is considered trivial? I thought that was a very cool way of putting it.
