Instruments » "Bass" in Jazz (~wikipedia)

Jazz bass is the use of the double bass, or in some genres bass guitar, to improvise accompaniment ("comping") and solos in a jazz or jazz fusion style. The double bass began being used in jazz in the 1890s, to supply the low-pitched walking basslines which outlined the harmony of the music. From the 1920s and 1930s Swing and big band era, through Bebop and 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 groups. Beginning in the late 1960s and early 1970s, some jazz fusion bandleaders began to substitute the electric bass guitar for the double bass.

Apart from the jazz styles of jazz fusion and Latin-influenced jazz and salsa, the double bass is still widely used in jazz. The sound and tone of the plucked double bass is distinct from that of the fretted bass guitar. The bass guitar produces a different sound than the double bass, because bass guitars usually have a solid wood body, which means that the sound is produced by electronic amplification of the vibration of the strings rather than from the resonance of the double bass' hollow body.

Most jazz bassists specialize in either the double bass or the electric bass; in some cases, though, performers achieve a high level of virtuosity on both instruments, such as Stanley Clarke and John Patitucci. Whether a jazz bassist is comping (accompanying) or soloing, or playing on a double bass or an electric bass, they usually aim to create a rhythmic drive and "timefeel" that creates a sense of "swing" and "groove".

Double bass

Beginning around 1890, the early New Orleans jazz ensemble (which played a mixture of marches, ragtime, and dixieland music) was initially a marching band with sousaphone (or occasionally bass saxophone) supplying the bass line. As the music moved into bars and brothels, the double bass gradually replaced these wind instruments. Many early bassists doubled on both the "brass bass" and "string bass," as the instruments were then often referred to. Bassists played "walking" basslines, scale-based lines which outlined the harmony.

Because an unamplified double bass is generally the quietest instrument in a jazz band, many players of the 1920s and 1930s used the slap style, slapping and pulling the strings so that they make a rhythmic "slap" sound against the fingerboard. The slap style cuts through the sound of a band better than simply plucking the strings, and allowed the bass to be more easily heard on early sound recordings, as the recording equipment of that time did not favor low frequencies. For more about the slap style, see "Playing styles," below.

Double bass players who have contributed to the evolution of jazz include swing era players such as Jimmy Blanton, who played with Duke Ellington, and Oscar Pettiford, who pioneered the instrument's use in bebop. The "cool" style of jazz was influenced by players such as Scott LaFaro and Percy Heath, whose solos were melodic. Paul Chambers (who worked with Miles Davis on the famous Kind of Blue album) achieved renown for being one of the first jazz bassists to play bebop solos in arco (bowed) style, though he was not the first player to do this. That honor goes to Slam Stewart, who would scat in octaves with his bowed bass in his solos, good examples of which can be found on the trio recordings he made with Art Tatum and Tiny Grimes.

Free jazz was influenced by the composer/bassist Charles Mingus (who also contributed to hard bop) and Charlie Haden, best known for his work with Ornette Coleman. Beginning in the 1970s, some jazz bandleaders such as saxophonist Sonny Rollins and fusion bassist Jaco Pastorius began to substitute the electric bass guitar for the double bass. Apart from the jazz styles of jazz fusion and Latin-influenced jazz, the double bass is still widely used in jazz. The sound and tone of the plucked double bass is distinct from that of the fretted bass guitar. The bass guitar produces a different sound than the double bass, because its strings are usually stopped with the aid of metal frets. As well, bass guitars usually have a solid wood body, which means that the sound is produced by electronic amplification of the vibration of the strings. The upright bass, normally in the solid "stick" variation (enabling much higher volume without feedback), is still widely favored by bass players in salsa and timba bands, because its sound is so well suited to those musical styles.


Playing techniques

In jazz, the double bass is usually played with amplification and it is mostly played with the fingers, pizzicato style, except during some solos, where players may use the bow. The pizzicato style varies between different players and genres. Some players perform with the sides of one, two, or three fingers, especially for walking basslines and slow tempo ballads, because this is purported to create a stronger and more solid tone. Some players use the more nimble tips of the fingers to play fast-moving solo passages or to pluck lightly for quiet tunes. The use of amplification allows the player to have more control over the tone of the instrument, because amplifiers have equalization controls which allow the bassist to accentuate certain frequencies (often the bass frequencies) while de-accentuating some frequencies (often the high frequencies, so that there is less finger noise).

An unamplified acoustic bass' tone is limited by the frequency responsiveness of the instrument's hollow body, which means that the very low pitches may not be as loud as the higher pitches. With an amplifier and equalization devices, a bass player can boost the low frequencies, which evens out the frequency response. As well, the use of an amplifier can increase the sustain of the instrument, which is particularly useful for accompaniment during ballads and for melodic solos with held notes. Like other acoustic instruments used with amplification, such as the jazz violin, a double bass is often plugged into a preamplifier, impedance-matching device, and/or a Direct Injection (DI box) box before it is routed to the PA system, electronic effects, or the bass instrument amplifier.

In traditional jazz and swing it is sometimes played in the slap style. This is a vigorous version of pizzicato where the strings are "slapped" against the fingerboard between the main notes of the bass line, producing a snare drum-like percussive sound. The main notes are either played normally or by pulling the string away from the fingerboard and releasing it so that it bounces off the fingerboard, producing a distinctive percussive attack in addition to the expected pitch. Notable slap style bass players, whose use of the technique was often highly syncopated and virtuosic, sometimes interpolated two, three, four, or more slaps in between notes of the bass line.


Variants

In both jazz and jazz fusion bands, some jazz bassists use a modified type of double bass called the electric upright bass (abbreviated EUB and sometimes also called stick bass). The stick bass is also widely used in salsa, because its volume and tone are especially suited to that style of music, even in studio recording. It is an electronically amplified version of the double bass that has a minimal or 'skeleton' body, which greatly reduces the size and weight of the instrument. The EUB retains enough of the features of the double bass so that double bass players are comfortable performing on it. While the EUB retains some of the tonal characteristics of the double bass, its electrically amplified nature also gives it its own unique sound. As well, an EUB is considerably easier to transport than its acoustic equivalent. The scale length of EUBs varies: some scales are 42", similar to most double basses, whilst other models have scale lengths of only 30" like a short scale bass guitar. The shorter scale can make it easier for bass guitarists to convert to the EUB.

Solid bodied EUBs produce very little sound without electronic amplification. Hollow-bodied EUBs produce a quiet tone that is loud enough for individual practice. However, since hollow-bodied EUBs do not have a large resonant cavity like a double bass, they cannot reproduce the lowest notes of the instrument without an amplifier. To amplify the EUB, the string vibrations are sensed with a pickup. Early EUBs used magnetic pickups similar to those in electric guitars, or percussive magnetic diaghram pickups (e.g., the Ampeg Baby Bass). Many modern EUBs use piezoelectric pickups located in the bridge or a combination of pickup types. The signal from the pickup is usually preamplified and equalized with a preamplifier and then sent to a bass amplifier or a PA system. For practice in a hotel room or apartment, an EUB can also be connected to headphones.

Preamplifiers and equalizers for acoustic instruments or double basses can also be used to "roll off" the treble frequencies or "notch out" the "scratchy-sounding" frequencies. Since the EUB typically does not have a hollow sound chamber, or only includes a small sound chamber, the EUB is less prone to feedback than the double bass when amplified. To use a bow with an EUB, both the bridge and fingerboard need to be radiussed (given a curve).


Electric bass

The electric bass is a relative newcomer to the world of jazz. The big bands of the 1930s and 1940s Swing era and the small combos of the 1950s Bebop and Hard Bop movements all used the double bass. The electric bass was introduced during the late 1960s and early 1970s, when rock influences were blended with jazz to create jazz-rock fusion. When the electric bass is used in jazz, it has both an accompaniment and a soloing role. When the bass is used to accompany, it may be used to perform walking basslines for traditional tunes and "jazz standards", in smooth quarter note lines which imitate the sound of the double bass. For latin or salsa tunes and rock-infused jazz fusion tunes, the electric bass may play rapid, syncopated rhythmic figures in coordination with the drummer, or lay down a low, heavy groove. In a jazz setting, the electric bass tends to have much a much more expansive solo role than in most popular styles. In most rock settings, the bass guitarist may only have a few short bass breaks or brief solos during a concert. During a jazz concert, a jazz bassist may have a number of lengthy improvised solos, which are called "blowing" in jazz parlance. Among those who have spearheaded the bass guitar in jazz are Jaco Pastorius, Victor Wooten, and Marcus Miller.


Fretted and fretless basses

One of the options for bass guitarists is whether to use an instrument with frets on the fingerboard or not. On a fretted bass, metal frets divide the fingerboard into semitone divisions (as on a guitar). The original Fender basses had 20 frets, but modern basses may have 24 or more. Fretless basses have a distinct sound, because the absence of frets means that the string must be pressed down directly onto the wood of the fingerboard as with the double bass. The string buzzes against the wood and is somewhat muted because the sounding portion of the string is in direct contact with the flesh of the player's finger. The fretless bass allows players to use the expressive devices of glissando, vibrato and microtonal intonations such as quarter tones and just intonation. Some bassists use both fretted and fretless basses in performances, according to the type of material they are performing. While fretless basses are often associated with jazz and jazz fusion, bassists from other genres use fretless basses, such as metal bassist Steve DiGiorgio.

Bill Wyman takes credit for creating the first fretless bass guitar in 1961 when he converted an inexpensive Japanese fretted bass by removing the frets. The first production fretless bass was the Ampeg AUB-1 introduced in 1966, and Fender introduced a fretless Precision Bass in 1970. In the early 1970s, fusion-jazz bassist Jaco Pastorius created his own fretless bass by removing the frets from a Fender Jazz Bass, filling the holes with wood putty, and coating the fretboard with epoxy resin.

Pastorius used epoxy rather than varnish to obtain a glass-like finish suitable for the use of roundwound strings, which are otherwise much harder on the wood of the fingerboard. Some fretless basses have "fret line" markers inlaid in the fingerboard as a guide, while others only use guide marks on the side of the neck. Tapewound (double bass type) and flatwound strings are sometimes used with the fretless bass so that the metal string windings will not wear down the fingerboard. Some fretless basses have fingerboards which are coated with epoxy to increase the durability of the fingerboard, enhance sustain and give a brighter tone. Although most fretless basses have four strings, five-string and six-string fretless basses are also available. Fretless basses with more than six strings are also available as "boutique" or custom-made instruments.


Alternative instruments

While the majority of jazz and jazz fusion recordings and live performances use either the double bass (or a related instrument such as an electric upright bass) or the electric bass to supply the "low end", there are some exceptions. In jazz organ trios, a Hammond organ player performs the basslines using the bass pedalboard or their lower manual, along with a drummer and a saxophonist. In some jazz fusion groups, the basslines may be played by a keyboard player on a bass synthesizer or other keyboard. As well, in some duos and other small groups, the basslines may be provided by a piano player; in a duo consisting of a jazz pianist and a jazz singer, the piano player plays a bassline with the left hand and chords in the right hand underneath the singer's voice. Similarly, in some duos or trios, a jazz guitarist may play basslines, a role that is especially feasible if the guitarist has a seven-string guitar with a low "B" string. In traditional Dixieland or New Orleans-style jazz groups, the basslines may be played by a tuba or other low brass instrument.
