<p>The debate over which aspects of musicianship are innate and which can be trained has raged among better scholars than me for decades if not centuries. I'm not sure what RBase07 means by "true perfect pitch," but check out the following link for some related research. It seems to me to suggest that perfect pitch CAN be trained in a large portion of the population if you start early enough.</p>
<p>I think we can all agree that there are certain individuals who just do not get it. No amount of training would ever prepare them to sing with a selective group other than mini's Crapapella.</p>
