R is for Reverb

Every space has a sound, like every person has a fingerprint.

We've talked a lot about the way that sound happens physically, and by now you probably can recite in your sleep the way that anything vibrating causes all sorts of disturbances amongst the air molecules surrounding it, and those air molecules then bump into their neighbours, and those into theirs, until the collisions eventually reach your ear.

At its most basic level this is where the conversation ends, because we haven't discussed what happens to the 99.999% of those air molecules that don't move in a direct line from the sound source to your ear drum. What happens is reverb.
