Resonance happens when an object vibrates at its natural frequency because of another nearby sound. It can make a musical instrument sound much louder or even shatter a glass with high-pitched notes. Every solid thing has a favorite vibration speed called its
natural frequency. When incoming sound waves push at exactly that speed, the object joins in and shakes harder and harder. The energy builds up instead of fading away.

A tuning fork can make another tuning fork of the same pitch start vibrating without touching it. The matching frequency passes energy through the air!
