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?

Because the explosions are happening in very, very, very, extremely fast succession. The sound blurs together creating the sound. Why do different types of engine sound different? Because they operate slightly different and thus sound slightly different. You asking why a v6 doesn’t sound like an I4 or whatever is like asking why a piano doesn’t sound like a guitar. Because they’re different things.
