There are all different types of music managers… But they can all be encompassed by this simple definition from the godfather of modern management himself, Peter Drucker:
Management is about human beings. Its task is to make people capable of joint performance, to make their strengths effective and their weaknesses irrelevant.
He gives a great definition of marketing too:
True marketing starts out with the customer, his demographics, his realities, his needs, his values. It does not ask, What do we want to sell? It asks, What does the customer want to buy? It does not say, This is what our product or service does. It says, These are the satisfactions the customer looks for, values, and needs.
