The bass guitar, electric bass or simply bass ( /bs/ ) is the lowest-pitched member of the guitar family. It is a plucked string instrument similar in appearance and construction to an electric or acoustic guitar, but with a longer neck and scale length, and typically four to six (or more) strings or courses. Since the mid-1950s, the bass guitar has largely come to replace the double bass in popular music due to its lighter weight, the use of frets (for easier intonation) and, most importantly, its design for electric amplification.


The four-string bass guitar is usually tuned the same as the double bass, which corresponds to pitches one octave lower than the four lowest-pitched strings of a guitar (typically E, A, D, and G). It is played primarily with the fingers or thumb, or with a pick. To be heard at normal performance volumes, electric bass guitars require external amplification.


According to the New Grove Dictionary of Music and Musicians, an "Electric bass guitar, usually with four heavy strings tuned E1'–A1'–D2–G2." [1] It also defines bass as "Bass (iv). A contraction of Double bass or Electric bass guitar." According to some authors the proper term is "electric bass". [2] [3] Common names for the instrument are "bass guitar", "electric bass guitar", and "electric bass" [4] [ page needed ] and some authors claim that they are historically accurate. [5] A bass guitar whose neck lacks frets is termed a fretless bass.


The scale of a bass is defined as the length of the freely oscillating strings between the nut and the bridge saddles. On a modern 4-string bass guitar, 30" (76 cm) or less is considered short scale, 32" (81 cm) medium scale, 34" (86 cm) standard or long scale and 35" (89 cm) extra-long scale. [6]


Bass pickups are generally attached to the body of the guitar and located beneath the strings. They are responsible for converting the vibrations of the strings into analogous electrical signals, which are in turn passed as input to an instrument amplifier. [7]


Bass guitar strings are composed of a core and winding. The core is a wire which runs through the center of the string and is generally made of steel, nickel, or an alloy. [8] The winding is an additional wire wrapped around the core. Bass guitar strings vary by the material and cross-sectional shape of the winding.

Common variants include roundwound, flatwound, halfwound (groundwound), coated, tapewound and taperwound (not to be confused with tapewound) strings. Roundwound and flatwound strings feature windings with circular and rounded-square cross-sections, respectively, with halfround (also referred to as halfwound, ground wound, pressure wound) strings being a hybrid between the two. Coated strings have their surface coated with a synthetic layer while tapewound strings feature a metal core with a non-metallic winding. [9] [10] [11] Taperwound strings have a tapered end where the exposed core sits on the bridge saddle without windings. [12] The choice of winding has considerable impact on the sound of the instrument, with certain winding styles often being preferred for certain musical genres. [13]

In the 1930s, musician and inventor Paul Tutmarc of Seattle, Washington, developed the first electric bass guitar in its modern form, a fretted instrument designed to be played horizontally. The 1935 sales catalog for Tutmarc's company Audiovox featured his "Model 736 Bass Fiddle", a solid-bodied electric bass guitar with four strings, a 30+12-inch (775-millimetre) scale length, and a single pickup. [14] Around 100 were made during this period. [15] Audiovox also sold their "Model 236" bass amplifier. [16]

In the 1950s, Leo Fender and George Fullerton developed the first mass-produced electric bass guitar. [17] The Fender Electric Instrument Manufacturing Company began producing the Precision Bass, or P-Bass, in October 1951. The design featured a simple uncontoured "slab" body design and a single coil pickup similar to that of a Telecaster. By 1957 the Precision more closely resembled the Fender Stratocaster with the body edges beveled for comfort, and the pickup was changed to a split coil design. [18]

The Fender Bass was a revolutionary instrument for gigging musicians. In comparison with the large, heavy upright bass, which had been the main bass instrument in popular music from the early 20th century to the 1940s, the bass guitar could be easily transported to shows. When amplified, the bass guitar was also less prone than acoustic basses to unwanted audio feedback. [19] The addition of frets enabled bassists to play in tune more easily than on fretless acoustic or electric upright basses, and allowed guitarists to more easily transition to the instrument. [20]

In 1953, Monk Montgomery became the first bassist to tour with the Fender bass, in Lionel Hampton's postwar big band. [21] [22] Montgomery was also possibly the first to record with the electric bass, on July 2, 1953, with the Art Farmer Septet. [23] Roy Johnson (with Lionel Hampton), and Shifty Henry (with Louis Jordan and His Tympany Five), were other early Fender bass pioneers. [17] Bill Black, who played with Elvis Presley, switched from upright bass to the Fender Precision Bass around 1957. [24] The bass guitar was intended to appeal to guitarists as well as upright bass players, and many early pioneers of the instrument, such as Carol Kaye, Joe Osborn, and Paul McCartney were originally guitarists. [19]

Also in 1953, Gibson released the first short-scale violin-shaped electric bass, the EB-1, with an extendable end pin so a bassist could play it upright or horizontally. In 1958, Gibson released the maple arched-top EB-2 described in the Gibson catalog as a "hollow-body electric bass that features a Bass/Baritone pushbutton for two different tonal characteristics". In 1959, these were followed by the more conventional-looking EB-0 Bass. The EB-0 was very similar to a Gibson SG in appearance (although the earliest examples have a slab-sided body shape closer to that of the double-cutaway Les Paul Special). The Fender and Gibson versions used bolt-on and set necks.

Several other companies also began manufacturing bass guitars during the 1950s. Kay Musical Instrument Company began production of the K162 in 1952, while Danelectro released the Longhorn in 1956. Also in 1956, at the German trade fair "Musikmesse Frankfurt" the distinctive Höfner 500/1 violin-shaped bass first appeared, constructed using violin techniques by Walter Höfner, a second-generation violin luthier. [25] Due to its use by Paul McCartney, it became known as the "Beatle bass". [26] In 1957, Rickenbacker introduced the model 4000, the first bass to feature a neck-through-body design in which the neck is part of the body wood. [27] The Burns London Supersound was introduced in 1958. [24]

With the explosion in popularity of rock music in the 1960s, many more manufacturers began making electric basses, including Yamaha, Teisco and Guyatone. Introduced in 1960, the Fender Jazz Bass, initially known as the "Deluxe Bass", used a body design known as an offset waist which was first seen on the Jazzmaster guitar in an effort to improve comfort while playing seated. [28] The Jazz bass, or J-Bass, features two single-coil pickups.

Providing a more "Gibson-scale" instrument, rather than the 34-inch (864 mm) Jazz and Precision, Fender produced the Mustang Bass, a 30-inch (762 mm) scale-length instrument. [29] The Fender VI, a 6 string bass, was tuned one octave lower than standard guitar tuning. It was released in 1961, and was briefly favored by Jack Bruce of Cream. [30]

Gibson introduced its short-scale 30.5-inch (775 mm) EB-3 in 1961, also used by Bruce. [31] The EB-3 had a "mini-humbucker" at the bridge position. Gibson basses tended to be instruments with a shorter 30.5" scale length than the Precision. Gibson did not produce a 34-inch (864 mm)-scale bass until 1963 with the release of the Thunderbird. [32]

The first commercial fretless bass guitar was the Ampeg AUB-1, introduced in 1966. [33] In the late 1960s, eight-string basses, with four octave paired courses (similar to a 12 string guitar), were introduced, such as the Hagström H8. [34]


In 1972, Alembic established what became known as "boutique" or "high-end" electric bass guitars. [35] These expensive, custom-tailored instruments, as used by Phil Lesh, Jack Casady, and Stanley Clarke, featured unique designs, premium hand-finished wood bodies, and innovative construction techniques such as multi-laminate neck-through-body construction and graphite necks. Alembic also pioneered the use of onboard electronics for pre-amplification and equalization. [36] [37]

Active electronics increase the output of the instrument, and allow more options for controlling tonal flexibility, giving the player the ability to amplify as well as to attenuate certain frequency ranges while improving the overall frequency response (including more low-register and high-register sounds). 1976 saw the UK company Wal begin production of their own range of active basses. [38] In 1974 Music Man Instruments, founded by Tom Walker, Forrest White and Leo Fender, introduced the StingRay, the first widely produced bass with active (powered) electronics built into the instrument. [39] Basses with active electronics can include a preamplifier and knobs for boosting and cutting the low and high frequencies.

In the mid-1970s, five-string basses, with a very low "B" string, were introduced. In 1975, bassist Anthony Jackson commissioned luthier Carl Thompson to build a six-string bass tuned (low to high) B0, E1, A1, D2, G2, C3, adding a low B string and a high C string. [40]

An electric guitar is a guitar that requires external amplification in order to be heard at typical performance volumes, unlike a standard acoustic guitar. It uses one or more pickups to convert the vibration of its strings into electrical signals, which ultimately are reproduced as sound by loudspeakers. The sound is sometimes shaped or electronically altered to achieve different timbres or tonal qualities from that of an acoustic guitar via amplifier settings or knobs on the guitar. Often, this is done through the use of effects such as reverb, distortion and "overdrive"; the latter is considered to be a key element of electric blues guitar music and jazz, rock and heavy-metal guitar-playing. Designs also exist combining attributes of the electric and acoustic guitars: the semi-acoustic and acoustic-electric guitars.

<span class="mw-page-title-main">Guitar</span> Fretted string instrument

The guitar is a stringed musical instrument, that is usually fretted and typically has six or twelve strings. It is usually held flat against the player's body and played by strumming or plucking the strings with the dominant hand, while simultaneously pressing selected strings against frets with the fingers of the opposite hand. A guitar pick may also be used to strike the strings. The sound of the guitar is projected either acoustically, by means of a resonant hollow chamber on the guitar, or amplified by an electronic pickup and an amplifier.

<span class="mw-page-title-main">Acoustic bass guitar</span> Type of acoustic instrument

The acoustic bass guitar is a bass instrument with a hollow wooden body similar to, though usually larger than, a steel-string acoustic guitar. Like the traditional electric bass guitar and the double bass, the acoustic bass guitar commonly has four strings, which are normally tuned E-A-D-G, an octave below the lowest four strings of the 6-string guitar.

<span class="mw-page-title-main">Neck-through-body construction</span> Method of electric guitar construction

Neck-through-body is a method of electric guitar construction that combines the instrument's neck and core of its body into a single unit. This may be made of a solid piece of wood, or two or more laminated together. The strings, nut, fretboard, pickups and bridge are all mounted on it, with additional body side components filling out its full shape glued or mechanically attached are referred to as "wings". The technique is also used on electric bass guitars.

<span class="mw-page-title-main">Fender Precision Bass</span> Model of electric bass

The Fender Precision Bass is a model of electric bass guitar manufactured by Fender Musical Instruments Corporation. In its standard, post-1957 configuration, the Precision Bass is a solid body, four-stringed instrument usually equipped with a single split-coil humbucking pickup and a one-piece, 20-fret maple neck with rosewood or maple fingerboard.

<span class="mw-page-title-main">Fender Jazz Bass</span> Fender model of bass guitar

The Fender Jazz Bass is the second model of electric bass created by Leo Fender. It is distinct from the Precision Bass in that its tone is brighter and richer in the midrange and treble with less emphasis on the fundamental frequency. The body shape is also different from the Precision Bass, in that the Precision Bass has a symmetrical lower bout on the body, designed after the Telecaster and Stratocaster lines of guitars, while the Jazz Bass has an offset lower bout, mimicking the design aesthetic of the Jaguar and Jazzmaster guitars.

<span class="mw-page-title-main">Jazz bass</span> Use of the double bass or electric bass guitar as a jazz instrument

Jazz bass is the use of the double bass or electric bass guitar to improvise accompaniment ("comping") basslines and solos in a jazz or jazz fusion style. Players began using the double bass in jazz in the 1890s to supply the low-pitched walking basslines that outlined the chord progressions of the songs. From the 1920s and 1930s Swing and big band era, through 1940s Bebop and 1950s Hard Bop, to the 1960s-era "free jazz" movement, the resonant, woody sound of the double bass anchored everything from small jazz combos to large jazz big bands.

<span class="mw-page-title-main">Pickup (music technology)</span> Captures vibrations produced by musical instruments

A pickup is a transducer that captures or senses mechanical vibrations produced by musical instruments, particularly stringed instruments such as the electric guitar, and converts these to an electrical signal that is amplified using an instrument amplifier to produce musical sounds through a loudspeaker in a speaker enclosure. The signal from a pickup can also be recorded directly.

<span class="mw-page-title-main">Electric upright bass</span>

The electric upright bass (EUB) is an instrument that can perform the musical function of a double bass. It requires only a minimal or 'skeleton' body to produce sound because it uses a pickup and electronic amplifier and loudspeaker. Therefore, a large resonating structure is not required to project the sound into the air. This minimal body greatly reduces the bulk and weight of the instrument. EUBs must always be connected to an amplifier and speaker cabinet to produce an adequate audible sound. The EUB retains enough of the features of the double bass so that double bass players are able to perform on it.

<span class="mw-page-title-main">String (music)</span> Sound producing musical instrument component

A string is the vibrating element of chordophones such as the guitar, harp, piano, and the violin family, that produces sound. Strings are lengths of a flexible material that a musical instrument holds under tension so that they can vibrate freely, but with control. This is to make the string vibrate at the desired pitch, while maintaining a low profile and sufficient flexibility to play in action.

<span class="mw-page-title-main">Fretless bass</span> String instrument

A fretless bass is an electric bass guitar whose neck is smooth like traditional string instruments, and like the acoustic upright double bass. As a guitar-like amplified alternative to this large and cumbersome instrument, the Fender Precision Bass was introduced in 1951, with frets to help guitarists who are used to them, to provide precision, and to offer a different sound. This concept has since become the standard, as other companies followed with similar electric fretted basses, like the Höfner 500/1 of Beatle Paul McCartney, which looked like a viol but with frets.

The Gibson EB-0 is a bass guitar that was introduced by Gibson in 1959. When production ceased in 1979, a total of 20,844 instruments had been built.

A solid-body musical instrument is a string instrument such as a guitar, bass or violin built without its normal sound box and relying on an electromagnetic pickup system to directly detect the vibrations of the strings; these instruments are usually plugged into an instrument amplifier and loudspeaker to be heard. Solid-body instruments are preferred in situations where acoustic feedback may otherwise be a problem and are inherently both less expensive to build and more rugged than acoustic electric instruments.

Electric guitar design is a type of industrial design where the looks and efficiency of the shape as well as the acoustical aspects of the guitar are important factors. In the past many guitars have been designed with various odd shapes as well as very practical and convenient solutions to improve the usability of the object.

<span class="mw-page-title-main">Bass guitar tuning</span>

Each bass guitar tuning assigns pitches to the strings of an electric bass. Because pitches are associated with notes, bass-guitar tunings assign open notes to open strings. There are several techniques for accurately tuning the strings of an electric bass. Bass method or lesson books or videos introduce one or more tuning techniques, such as:
