If a man lose his balance, and immerse himself in any trades or pleasures for their own sake, he may be a good wheel or pin, but he is not a cultivated man.
Jazz is an endless source of ideas, because you can use anything. You can play operatic arias. You can incorporate them into jazz. You can play gypsy music and incorporate it into jazz. You can European classical and you can incorporate it into jazz. You can use anything and jazz it up, as they used to say.
