Start playing music during childhood has strong positive impact on brain. If they are not going to become the new Mozart, the grey matter will be stronger and more developed. A study published in the Journal of Neuroscience has recommended starting to play music early, maximum 7 years old. If not, the benefits are fewer and will not be comparable with those obtained at later age. In fact, between 6 and 8, children create a “window of learning” which is much larger than in any other moment of their life. The research has been led to 36 participants and has showed that early-trained musicians had greater connectivity in the corpus callosum. This has favoured better sensory-motor synchronization.
