The guitar is a musical instrument with ancient roots that is used in a wide variety of musical styles. It typically has six strings, but four, seven, eight, ten, and twelve string guitars also exist.
Guitars are recognized as one of the primary instruments in blues, country, flamenco, rock music, and many forms of pop. There is also a solo classical instrument. Guitars may be played acoustically, where the tone is produced by vibration of the strings and modulated by the hollow body, or they may rely on an amplifier that can electronically manipulate tone. Such electric guitars were introduced in the 20th century and continue to have a profound influence on popular culture.
Traditionally guitars have usually been constructed of combinations of various woods and strung with animal gut, or more recently, with either nylon or steel strings. Guitars are made and repaired by luthiers.
The long-established manufacturers of electric basses have never used "bass guitar" to label their instruments. It could be argued that "bass guitar" originated in retail catalogues and the phrase has since gained popular currency among the masses.
The electric bass is the standard bass instrument in many musical genres, including country, jazz, many flavors of rock and roll, soul, funk, and modern orchestral music.
As with the electric guitar, vibrations of the metal strings create electrical signals in electromagnetic sensors called pickups. The signals are then amplified and played through a speaker. Various electronic components, and the configuration of the amplifier and speaker, can be used to alter the basic sound of the instrument.
The necessity for a louder individual bass instrument can be traced back to the 1920s. Jazz combos had double basses accompanying banjos, brass and woodwind sections, pianos, and drums. Simply being heard was hard, and transporting a double bass was even harder.
The design that would attract bass players was an electric bass that was a compact, fretted instrument one could hold and play horizontally. This was achieved by a musician/teacher/instrument & amplifier maker named Paul H. Tutmarc, of Audiovox in Seattle, Washington.
Tutmarc had an upright solidbody electric bass on the market as early as February 1935. But it is the #736 Electronic Bass advertised in 1937 that was probably the world’s first fretted solid body electric bass played horizontally and pioneered the modern bass configuration. The change to the guitar form and the addition of frets made the instrument much easier (and more precise) to play. Unfortunately, the Audiovox company were ultimately not successful and folded around 1950.
The first mass-produced electric bass was developed by innovator and manufacturer Leo Fender in the early 1950s. Fender trained as an accountant and was a self-taught electrical engineeer who started repairing radios and built P.A systems before getting into the electronics and amplification of electric instruments. Interestingly, Leo Fender could not even play guitar or bass, by his own admission "not a note".
The Fender Precision Bass was first offered in 1951. Named for the exact intonation a player could achieve with its fretted neck, the Precision Bass was equipped with a single piece, four-pole pickup, and a simple, uncontoured 'slab' body design. In 1954 the body was contoured with beveled edges for comfort. In 1957, the pickup was changed to a single "split pickup" (staggered) design. The pickguard also underwent a radical change, as did the headstock.
This 1957 design has remained as the standard electric bass, and is still widely available. Another industry standard, the similar, but more highly-engineered Fender Jazz Bass, was introduced in 1960.
Following Fender's lead, other companies such as Gibson, Danelectro, and many others started to produce their own version of the electric bass. The upright double bass became functionally obsolete in most kinds of popular music, allowing bassists to move further up front in the band mix, both visually and audibly. Innovations and refinements continue through to the present day.
Although the classic 4-String Fender bass designs remain a popular choice amongst player and hybrid basses are sometimes cringed upon, general open-mindedness towards new technologies and musical instrument design as well as appreciation for unique luthery in bass playing community causes the modern bass player to have a wide range of choices when choosing an instrument. Design options include:
Add in the factors of amplification and effects units and the electric bass has an overwhelming amount of tonal flexibility.
The fretted acoustic bass is similar to an acoustic guitar with a large, hollow body that is clearly audible without amplification. However, they are relatively quiet compared to most other acoustic instruments, and many guitar-style modern acoustic basses are equipped with pickups to enable them to function with louder ensembles, while still maintaining some of the acoustic characteristics of the sound. See the Violent Femmes' first album for an example of acoustic bass playing in modern rock music.
As with any instrument, the electric bass can be played in a number of styles. Players such as Paul McCartney tend to favor a subdued, melodic approach, while Les Claypool of Primus and Flea of Red Hot Chili Peppers favor a funky "slap and pop" approach in which notes and percussive sounds are created by slapping the string with the thumb and release strings with a snap. Many artists, such as Pino Palladino utilize a fretless bass guitar for the smoothness of its slide and unique tone.
The slap and pop method was pioneered by Larry Graham in the 1960s. Graham's unique sound gained a broad audience when it appeared in the 1970 Sly and the Family Stone song "Thank You (Falettinme Be Mice Elf Agin)". In the 1970s Stanley Clarke developed Graham's technique further, adding the popping and speed that are a hallmark of contemporary playing.
An even later development is the two-handed tapping style, where both hands play notes by tapping the string to the fret. This makes it possible to play contrapuntally, or to play complicated chords and arpeggios. Since this makes the bass take up a large part of the aural spectrum, it is mostly used by bass players who act as the lead in their music. Notable examples are Stuart Hamm, whose music is Metal-oriented, and Michael Manring, who has a more jazzy / new age style. Manring occasionally plays on two (or even three) basses at the same time, much like Stanley Jordan on guitar. However, as a more traditional bass player, Jeff Berlin, has noted: no bass player was ever hired for his two-hand tapping skills.
Most bassists prefer to pluck the notes with the fingers but some also use plectra (also called picks). This often varies according to the musical genre—very few funk bassists use plectrums, while they are almost de rigueur for punk rock. Using a plectrum typically gives the bass a brighter, more punchy sound, while playing with one's fingers makes the sound more soft and round.
Variations in style also occur in where a bassist rests his thumb (if he does rest it at all...). One may rest his thumb on the side of the fretboard, which is especially common among bassist who have an upright bass influence. Also, bassists with more than 4 string basses, may utilize a low string which isn't often used, for thumb rest. By resting their thumb to anchor their hand while they use their index and middle fingers, bassists create a fuller and louder sound.
Interestingly, one of the greatest bassists ever, James Jamerson, well known for his work in many popular motown songs, played the bass with only his index finger, and many of his bass lines were more complex than some of the great modern bassists of today who use both their index and middle fingers.
Bassists also have different preferences as to where on the string they pluck the notes. While the influential bassist Jaco Pastorius and many with him preferred to pluck them very close to the bridge for a bright and sharp sound, many prefer the rounder sound they get by plucking closer to the neck, mostly near the neck pickup. Geezer Butler, among others, plucks the strings over the higher frets.
Bass players like Chris Squire, Michael Balzary (a.k.a Flea) and John Entwistle have been revolutionary by taking a more important, leading, complicated role and making the instrument a more important and recognised one, a trend that caught on in bands that followed them.
