what classic books should I read to expand my vocabulary?

I’m looking to expand my vocabulary and metaphors, what classic books should I read for this? Please recommend what you think is best for what I’m asking. I'm doing this because I'm a musician and I've noticed I've been having trouble writing later and Its because I've been having trouble with words, I really like miracle musical and the words Joe Hawley uses. Like albeit or when he says thy genius dates a thirst for trouble and serfs. All those things.
