In 1929, when the stock market crash resulted in a global depression, one of the things that helped people cope with the trying years was swing jazz music. By the early to mid 1930's, big band swing was being embraced throughout the US, becoming the country's most popular form of music. The other contributing factor to the big band's success during the 1930s was the popularity of radio. The drum kit played a key role in the big band swing sound. Throughout the 1930s Chick Webb and Gene Krupa at the Savoy Ballroom in Harlem, increased the visual and musical driving force of the drummer and their equipment by simply being so popular and in demand- and they ensured that their drum kits became not only functionally developed but dazzling and well designed. Jazz drummers were influential in developing the concept of the modern drum kit and extending playing techniques. Gene Krupa was the first drummer to head his own orchestra and thrust the drums into the spotlight with his drum solos. Others would soon follow his lead.
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).
During the 1990s, as five-string basses became more widely available and more affordable, an increasing number of bassists in genres ranging from metal to gospel began using five-string instruments for added lower range—a low "B" string. As well, onboard battery-powered electronics such as preamplifiers and equalizer circuits, which were previously only available on expensive "boutique" instruments, became increasingly available on mid-priced basses. From 2000 to the 2010s, some bass manufacturers included digital modelling circuits inside the instrument on more costly instruments to recreate tones and sounds from many models of basses (e.g., Line 6's Variax bass). A modelling bass can digitally emulate the tone and sound of many famous basses, ranging from a vintage Fender Precision to a Rickenbacker. However, as with the electric guitar, traditional "passive" bass designs, which include only pickups, tone and volume knobs (without a preamp or other electronics) remained popular. Reissued versions of vintage instruments such as the Fender Precision Bass and Fender Jazz Bass remained popular amongst new instrument buyers up to the 2010s. In 2011, a 60th Anniversary P-bass was introduced by Fender, along with the re-introduction of the short-scale Fender Jaguar Bass.
In traditional music such as country music, folk rock, and related styles, the bass often plays the roots and fifth (typically the fifth below the root) of each chord in alternation. In these styles, bassists often use scalar "walkups" or "walkdowns" when there is a chord change. In Chicago blues, the electric bass often performs a walking bassline made up of scales and arpeggios. In blues rock bands, the bassist often plays blues scale-based riffs and chugging boogie-style lines. In metal, the bass guitar may perform complex riffs along with the rhythm guitarist or play a low, rumbling pedal point to anchor the group's sound.
Depending on the individual features of each digital piano, they may include many more instrument sounds other than regular piano samples. Many less expensive or average-priced digital pianos often include basic instruments such as string ensemble, electric piano, organs, harpsichord, guitar, and vibraphone, while a more expensive and advanced digital pianos may have a wider range of instruments such as synthesized sounds, wind instruments, traditional instruments, violins, drums, percussion, and a variety of effects, similar to that of a typical digital keyboard or synthesizer. Some digital pianos may also have a complete set of General MIDI implementation, in addition to the aforementioned basic sounds.
