He liked to think that he wasn’t afraid of death. It was life he was afraid of, not death. He believed that people should think about death more often, and accustom themselves to the notion of it. Just letting it creep up on you unnoticed was not the best way to live. You should make yourself familiar with it. You should write about it: either in words or, in his case, music. It was his belief that if we thought about death earlier in our lives, we would make fewer mistakes. Not that he hadn’t made a lot of mistakes himself.
