It is generally believed that early music training can enhance an individual's musical sound and speech processing ability  But some psychologists doubt this  Researchers investigated 1211 pairs of identical twins and 1358 pairs of fraternal twins born between 1959 and 1985, recorded their music practice time and evaluated their music ability  They found that, Practicing for a longer time does not show better musical ability  For example, a pair of identical twins with the same gene have 20228 hours of musical practice time difference, but their musical ability is exactly the same
Musical ability assessment uses fingers to simulate fast-paced music, and finger flexibility is genetically affected
 These researchers believe that without the correct gene, it is meaningless to practice for 20000 hours, and the musical ability is determined by the gene
