Drum Kit

The drum is a member of the percussion group of musical instruments, technically classified as the membranous. Drums consist of at least one membrane, called a drumhead or drum skin, that is stretched over a shell and struck, either directly with the player's hands, or with a drumstick, to produce sound.

A drum kit (also known as drum set or trap set) is a collection of drums, cymbals and often other percussion instruments, such as cowbells, wood blocks, triangles, chimes, or tambourines, arranged for convenient playing by a single person (drummer).

An electronic drum is a percussion instrument in which the sound is generated by an electronic waveform generator or sampler instead of by acoustic vibration.

When an electronic drum pad is struck, a voltage change is triggered in the embedded piezoelectric transducer (piezo) or force sensitive resistor (FSR). The resultant signals are transmitted to an electronic "drum brain" via TS or TRS cables, and are translated into digital waveforms, which produce the desired percussion sound assigned to that particular trigger pad.

Most newer drum modules have trigger inputs for 2 or more cymbals, a kick, 3-4 toms, a dual-zone snare (head and rim), and a hi-hat. The hi-hat has a foot controller which produces open and closed sounds with some models offering variations in-between. By having the ability to assign different sounds to any given pad, the electronic drummer has nearly unlimited potential for configuring many different sounding drum kits from one set of electronic drums.

Additionally, electronic drummers can sample non-percussive sounds and use them as drum sounds, as is the case with most industrial music. Many see this as a great advantage over acoustic drums, as one can have a jazz, rock or ballad drumset by merely changing the kit selector switch on the module.
