CM started as a reaction against the exclusive culture of "high art music"
Because it was a reactionary movement based in a sense of lack of access or unjust treatment. . . CM is rooted in social justice, fairness, equality, equity, learning for all, intergenerational, etc. Universal human values. That's the culture.
CM didn't like that in order to access music you needed money, tons of training, knowing the right people, having the right education from birth, etc.
Music is a right, a human right.
What about the sounds themselves? Ah, there's the first tripping point.
