When comparing a motor skill between the two groups, musicians who began before age seven showed more accurate timing, even after two days of practice. When comparing brain structure, musicians who started early showed enhanced white matter in the corpus callosum, a bundle of nerve fibres that connects the left and right motor regions of the brain. Importantly, the researchers found that the younger a musician started, the greater the connectivity.
Interestingly, the brain scans showed no difference between the non-musicians and the musicians who began their training later in life; this suggests that the brain developments under consideration happen early or not at all. Because the study tested musicians on a non-musical motor skill task, it also suggests that the benefits of early music training extend beyond the ability to play an instrument.
"This study is significant in showing that training is more effective at early ages because certain aspects of brain anatomy are more sensitive to changes at those time points," says co-author, Dr. Zatorre, who is also the co-director of the International Laboratory for Brain Music and Sound Research.
But, says Penhune, who is also a member of the Centre for Research in Human Development, "it's important to remember that what we are showing is that early starters have some specific skills and differences in the brain that go along with that. But, these things don't necessarily make them better musicians. Musical performance is about skill, but it is also about communication, enthusiasm, style, and many other things that we don't measure. So, while starting early may help you express your genius, it probably won't make you a genius."
