I think music should be learnt by choice, not as a compulsory subject in schools. You can't teach someone to become passionate and you certainly can't teach talent, so someone has to be talented already and then passionate enough to choose it for themselves in my opinion.
That's a valid point, but teaching how music is socially, personally and emotionally important should be the way to go. They don't need to make the mechanics of music compulsory learning, only the effect it has on people.....which has been scientifically proven.
