Absolute pitch is considerably more common among those whose early childhood was spent in East Asia. This might seem to be a genetic difference; however, people of East Asian ancestry who are reared in North America are significantly less likely to develop absolute pitch than those raised in East Asia, so the difference is more probably explained by experience. The language that is spoken may be an important factor; many East Asians speak tonal languages such as Mandarin and Cantonese, while others (such as those in Japan and certain provinces of Korea) speak pitch-accent languages, and the prevalence of absolute pitch may be partly explained by exposure to pitches together with meaningful musical labels very early in life.
