Popular music bands and rock groups use the bass guitar as a member of the rhythm section, which provides the chord sequence or "progression" and sets out the "beat" for the song. The rhythm section typically consists of a rhythm guitarist or electric keyboard player, or both, a bass guitarist and a drummer; larger groups may add additional guitarists, keyboardists, or percussionists.
Timbales are tuned much higher than a tom of the same diameter, and normally played with very light, thin, non-tapered sticks. They have relatively thin heads and a very different tone than a tom, but are used by some drummers/percussionists to extend the tom range upwards. Alternatively, they can be fitted with tom heads and tuned as shallow concert toms. Attack timbales and mini timbales are reduced-diameter timbales designed for drum kit usage, the smaller diameter allowing for thicker heads providing the same pitch and head tension. They are recognizable in 2010s genres and in more traditional forms of Latin, reggae & numerous world music styles. Timbales were also used on occasion by Led Zeppelin drummer John Bonham. Gong drums are a rare extension to a drum kit. The single-headed mountable drum appears similar to a bass drum (sizing around 20–24 inches in diameter), but has the same purpose as that of a floor tom. Similarly, most hand drum percussion cannot be played easily or suitably with drum sticks without risking damage to the head and to the bearing edge, which is not protected by a metal drum rim, like a snare or tom. For use in a drum kit, they may be fitted with a metal drum head and played with care, or played by hand.
Most five-piece kits, at more than entry level, also have one or more effects cymbals. Adding cymbals beyond the basic ride, hi-hats and one crash configuration requires more stands in addition to the standard drum hardware packs. Because of this, many higher-cost kits for professionals are sold with little or even no hardware, to allow the drummer to choose the stands and also the bass drum pedal he/she prefers. At the other extreme, many inexpensive, entry-level kits are sold as a five-piece kit complete with two cymbal stands, most often one straight and one boom, and some even with a standard cymbal pack, a stool and a pair of 5A drum sticks. In the 2010s, digital kits are often offered in a five-piece kit, usually with one plastic crash cymbal triggers and one ride cymbal trigger. Fully electronic drums do not produce any acoustic sound beyond the quiet tapping of sticks on the plastic or rubber heads. The trigger-pads are wired up to a synth module or sampler.
