Electronic drums is a modern electronic musical instrument, primarily designed to serve as an alternative to an acoustic drum kit. Electronic drums consist of an electronic sound module which produces the synthesized or sampled percussion sounds and a set of 'pads', usually constructed in a shape to resemble drums and cymbals, which are equipped with electronic sensors (or triggers) to send an electronic signal to the sound module which outputs a sound to the player. Like regular drums, the pads are struck by drum sticks and they are played in a similar manner to an acoustic drum kit, albeit some differences in the drumming experience.
