Early musical training appears to be necessary but not sufficient for the development of AP. Forty percent of musicians who had begun training at ≤4 years of age reported AP, whereas only 3% of those who had initiated training at ⩾9 years of age did so. Self-reported AP possessors were four times more likely to report another AP possessor in their families than were non–AP possessors. These data suggest that both early musical training and genetic predisposition are needed for the development of AP.
Thanks for the quote and link. I do appreciate those who make the internet a better place even though they toss around a slightly passive aggressive advice along the way!
