I have been reading some serious social theory books recently in connection with some developments at work, and a couple of days ago I came across this argument in Keith Negus' book, "The Theory of Popular Music".
Music does not change the world, but it can change the people in the world, because it can change the way they feel. In particular, it can create an emotional bond with other people who share music with you.
I meet and play music with people of many countries and cultures, and that has changed the way I feel, and accordingly, the way I act towards those people and cultures.
As a result of music, I do feel a kinship with people of China, Nepal, West Africa, Bangla Desh, Iran, etc, etc....
My reaction to news stories from those countries is moderated accordingly.
So I go out and I argue those points. When I meet somebody in a position of influence, I talk about it. When I teach, those attitudes are overt in the things I teach.
I will do my best to change the world, and if that is not much, well, a little is better than nothing!
Cheers
