Warming-up is a custom job. It has to fit the individual and be altered from time to time as we change. Warming-up is not just a trombone thing. Dancers warm-up, athletes warm-up. Even people meeting each other have to warm-up to each other and not take for granted, by being too familiar and assuming they already know where the other person is at or feeling that day. Warming-up is a respectful and considerate attitude and practice and demonstrates a care to our body-mind-soul that we want to take care of it and are thankful for the service it has given us.
