Classical music mostly centered in a continent called Europe, and especially in a country called Austria. While that era was happening, I don't think instruments like trumpets and pianos and violins had even been seen in Japan yet. But over time, the genre spread all across the world.

That's pretty magical to me. I don't know English, or any other European language, but music breaks all those barriers. It doesn't matter where you're from; humans love music everywhere. It's a language we all understand.
