Several recent large-scale studies have confirmed a curious finding: Asians are much more likely to have “perfect pitch” than non-Asians. Perfect pitch, more properly called “Absolute pitch,” is an extremely rare phenomenon, but it’s several times more likely to occur in Asians than in others.
While the lack of BO is genetic, this perfect pitch thing doesn’t seem to be. Rather, it appears to be cultural.
Other research has found that nearly all of the Asian advantage in absolute pitch is found among Asians who spent their early childhood in Asia. This again points to cultural, not genetic factors.
The cultural factor probably explains why I’m absolutely terrible when it comes to music. I’m just not Chinese enough. But at least I don’t stink.
