Has anyone tried Perfect Pitch® Ear Training SuperCourse by David Lucas Burge?

I found a course for teaching perfect pitch that is a set of CDs that can be purchased and I was wondering if anyone had tried it. It is Perfect Pitch® Ear Training SuperCourse, by David Lucas Burge and the website is http://www.perfectpitch.com/home.htm

It is pretty pricey, but I would love to hear if anyone has found it a good way to teach prefect pitch.

No, I haven’t tried that method, but I also came across some research that perfect pitch is actually not beneficial, that people with perfect pitch have trouble focusing, etc. I am still trying to figure out if perfect pitch is something I want my child to have. Maybe I will put up a post and ask what other mothers think.
