Chosen answer:No, it is not normal to bleed while playing drums, as callouses develop on a drummer's hands through constant practising and playing. But, if a drummer plays hard enough and fast enough using the same drum sticks, friction between wood and skin can develop and rupture toughened skin. In the context of the film, the drummer is being pushed beyond his limits by the music conductor. Additionally, he is pushing himself to be better, so the bleeding is a consequence of that drive for excellence.
