How do internal combustion engines (ICE) get their characteristic sound, if it’s only just a bunch of explosions?

I know how engines work, what makes them work etc. but this question has been on my mind for a while. How can a bunch of controlled explosions create the sound characteristic for a specific engine type? For example, a V6 engine sounds distinctly different than a V8 or I4, but how do they get their sound & why can’t the sound be different, for example an I4 engine with the sound of a V12?

There’s a lot of info here but I feel like no one is talking about how crankshaft geometry affects the sound.
