I found a short and interesting article on the connections between music lessons and auditory processing and thought I'd share -
"Your child doesn't have to be the next Louis Armstrong to benefit from music lessons. Even a brief period of playing an instrument could help him hear better when he grows up, researchers at Northwestern University say. In their study, adults who received music instruction in childhood - some for even just one or two years - were better than people with no musical training at picking up on the fundamental frequency of sound waves, an aspect of hearing well in noisy environments. Early music-making might shape certain structures in the brain stem, where auditory signals are processed."
How about that fun fact?
