A child prodigy is defined in psychology research literature as a person under the age of ten who produces meaningful output in some domain to the level of an adult expert performer.[1][2][3] This is a list of young children (under around age 10) who displayed a talent in music deemed to make them competitive with skilled adult musicians. The list is sorted by instrument.
For the purposes of this and future research, a prodigy was defined as a child younger than 10 years of age who has reached the level of a highly trained professional in a demanding area of endeavor.
At the moment, the most widely accepted definition is a child, typically under the age of 10, who has mastered a challenging skill at the level of an adult professional.
