To make a sound with a drum, you beat it, tap it, strike it, hit it, pound it, or brush it. Drums consist of stretched membranes over an open cavity, such that striking the membrane causes a resonance. Drums can be struck with the hands, with drumsticks, or with brushes (as on a snare drum). The largest bass drums use either handheld mallets or mechanical beaters, which are activated by pedals.
