How can we explain the vast differences in musical ability? How can one species produce Paul Simon and William Hung? Are we born with musical talent, or do we develop it? Let's sort through the research:
- Two-day old infants show a preference for some music over others (N. Masataka, 1999).
- Nearly all infants babble with melody and intonation (Gardner, 1997, p. 251).
- At 1, children can often match pitch (Kessen, Levine & Peindich, 1978).
- At 1 1/2, children engage in spontaneous song (Kessen, Levine & Peindich, 1978)
- At 2 1/2, children show extended awareness of songs by others (Davidson, 1994, in R. Aiello)
- "Musical development continues beyond the age of 7 or so only in an environment that provides some sort of tutelage." (Gardner, 1997, p. 253; Gardner, 1973; Winner, 1982)
- Absolute ("perfect") pitch is not a genetic accident or random occurrence, but is developed in young childhood under specific external conditions (D. Deutsch, 2004; Takeuchi & Hulse, 1993).
- "Talent proves of no avail in the absence of thousands of hours of practice distributed over a decade or more, as the youngster gains facility in various first- and second-order musical symbol systems. (Gardner, 1997, p. 256).
- The very best professional musicians practice the most and the smartest compared to the next best group of professional musicians, who in turn practice more and better than the third-best group (Ericsson et al, 1993). Top musicians consistently require about ten years and 10,000 hours of practice to achieve the height of their virtuoso skill-level.
- Among student musicians, the best ones also practice more than the next-best, who practice more and better than the ones who eventually drop out (Sloboda, Davidson, Howe, and Moore, 1996).
- "Deliberate practice" is qualitatively different from ordinary experience. In ordinary experience, an individual is exposed to certain task demands, spends time attaining proficiency at that task and then plateaus, more or less satisfied with his/her level of competence. Under these passive circumstances, more time spent with the same task after the plateau will not significantly increase skill-level. The skill level becomes autonomous and stable. In contrast, under a regime of deliberate practice, the individual is never quite satisfied and is always pushing a little bit beyond his/her capability, actively and incrementally expanding that capability. (Ericsson, 2006, chapter 38).
- Francis Galton, the father of eugenics and theories of innate talent, suggested that individuals pursuing a skill naturally rise to an innate limit of their capability. The work of Ericsson and others suggests that this is nonsense -- that in many if not most cases these limits are not innate but connected to the quantity and quality of training, and to an individual's level of ambition/determination.
- Right-handers not trained in music show typical right-hemisphere processing, while right-handers trained in music show left-hemisphered dominance (Bever & Chiarello, 1974)
- Cortical representations of fingers of the left hands of string players get significantly enlarged compared to non-musicians -- and moreso for those who train earlier in life. (Elbert et al, 1995)
