and in fact it does not even make me a better me...
I disagree with you right about there.
Understanding (and performing) music involves skills many do not have (or have not developed).
I firmly believe the ability to read/play music develops fundamental skill sets many do not understand or appreciate.
2nd language
math (in real time)
discipline
many others. ..
Music does improve your learning/comprehension; therefore affecting the better 'you'.
I'm a firm believer in that. I can cite studies, but don't care to argue this. Just something for consideration.
