<p>I wonder if there is a correlation between perfect pitch and an early start on violin? Two of my five kids have perfect pitch (the kind where you are just eating dinner or something, and you say sing me an "a" and they sing it and then you check it and it is right on) I wonder if they developed it by learning violin at an early age. It was obvious with the older child very early. When he was in kindergarten he criticized a substitute teacher for singing one of the songs a half note off, and he was right. It just started becoming obvious with the second child about a year ago (11 years old), so I think there is a possiblity that the little one might also develop it (also started violin at an early age) or it might be there, waiting to make itself known, if you will. The other two who did not play violin definitely do not have it.</p>
