Rhythm is simply a pattern of sound and silence that repeats over time. You do not need a drum to find one: put two fingers on your wrist or neck and you can feel your own heartbeat thumping in a steady pattern right now. A ticking clock, dripping tap, or your footsteps walking down a hallway are all rhythms too. Musicians did not invent rhythm, they just noticed it was already hiding in nature and in our bodies, then borrowed it for songs. The word "rhythm" even comes from an old Greek word meaning "measured flow," which is a fancy way of saying "a pattern that keeps moving."
