Many drummers extend their kits from this basic configuration, adding more drums, more cymbals, and many other instruments including pitched percussion. In some styles of music, particular extensions are normal. For example, rock and heavy metal drummers make use of double bass drums, which can be achieved with either a second bass drum or a remote double foot pedal. Some progressive drummers may include orchestral percussion such as gongs and tubular bells in their rig. Some performers, such as some rockabilly drummers, play small kits that omit elements from the basic setup. Some drum kit players may have other roles in the band, such as providing backup vocals, or less commonly, lead vocals.
In 1918 Baby Dodds (Warren "Baby" Dodds, circa 1898–1959), playing on riverboats with Louis Armstrong on the Mississippi, was modifying the military marching set-up and experimenting with playing the drum rims instead of woodblocks, hitting cymbals with sticks (1919), which was not yet common, and adding a side cymbal above the bass drum, what became known as the ride cymbal. Drum maker William Ludwig developed the "sock" or early low-mounted high-hat after observing Dodd's drumming. Ludwig noticed that Dodd tapped his left foot all the time. Dodds had Ludwig raise the newly produced low hats 9 inches higher to make it easier to play, thus creating the modern hi-hat cymbal. Dodds was one of the first drummers to also play the broken-triplet beat that became the standard pulse and roll of modern ride cymbal playing. Dodds also popularized the use of Chinese cymbals.
Electronic drum pads are the second most widely used type of MIDI performance controllers, after electronic music keyboards.:319–320 Drum controllers may be built into drum machines, they may be standalone control surfaces (e.g., rubber drum pads), or they may emulate the look and feel of acoustic percussion instruments. The pads built into drum machines are typically too small and fragile to be played with sticks, and they are usually played with fingers.:88 Dedicated drum pads such as the Roland Octapad or the DrumKAT are playable with the hands or with sticks, and are often built to resemble the general form of a drum kit. There are also percussion controllers such as the vibraphone-style MalletKAT,:88–91 and Don Buchla's Marimba Lumina.
In other less mainstream genres, such as hardcore punk or metal, the pedagogical systems and training sequences are typically not formalized and institutionalized. As such, many players learn by ear, by copying bass lines from records and CDs, and by playing in a number of bands. Even in non-mainstream styles, though, students may be able to take lessons from experts in these or other styles, adapting learned techniques to their own style. As well, there are a range of books, playing methods, and, since the 1990s, instructional DVDs (e.g., how to play metal bass). In the 2010s, many instructional videos are available online on video-sharing websites such as YouTube.
Sticks were traditionally made from wood (particularly maple, hickory, and oak} but more recently metal, carbon fibre and other exotic materials have been used for high market end sticks. The prototypical wooden drum stick was primarily designed for use with the snare drum, and optimised for playing snare rudiments. Sticks come in a variety of weights and tip designs; 7N is a common jazz stick with a nylon tip, while a 5B is a common wood tipped stick, heavier than a 7N but with a similar profile, and a common standard for beginners. Numbers range from 1 (heaviest) to 10 (lightest).
Something else that you might like to consider is taking a cue from the bassists who have inspired you. Music is an art in which there's no shame in having an idol, and with plenty of signature bass guitars available, you can gear yourself up to follow in legendary footsteps. Take the Fender Jaco Pastorius Fretless Jazz Bass Guitar, for instance. Meticulously modelled after Jaco's own instrument, it carries on his spirit with a fretless design that lets you really unleash your creativity on the stage.
