A twelve-string guitar (or 12-string guitar) is a steel-string guitar with 12 strings in six courses, which produces a thicker, more ringing tone than a standard six-string guitar. Typically, the strings of the lower four courses are tuned in octaves, with those of the upper two courses tuned in unison. The gap between the strings within each dual-string course is narrow, and the strings of each course are fretted and plucked as a single unit. The neck is wider, to accommodate the extra strings, and is similar to the width of a classical guitar neck. The sound, particularly on acoustic instruments, is fuller and more harmonically resonant than six-string instruments. The 12-string guitar can be played like a 6-string guitar as players still use the same notes, chords and guitar techniques like a standard 6-string guitar, but advanced techniques can be challenging as players need to play or pluck two strings simultaneously.
Structurally, 12-string guitars, especially those built before 1970, differ from six-string guitars in the following ways:
Twelve-string guitars are made in both acoustic and electric forms. However, the acoustic type is more common.
The double ranks of strings of the 12-string guitar produce a shimmering effect, because even the strings tuned in unison can never vibrate with precise simultaneity—that is, they vibrate out of phase. The result to the ear is a sound that seems to "shimmer", which some describe as resembling strings that are slightly detuned. The interference between the out-of-phase vibrations produces a phenomenon known as a beat that results in a periodic rise and fall of intensity which is, in music, often considered pleasing to the ear. Pete Seeger described the distinctive sound of the 12-string guitar as "the clanging of bells." [1] [2] [3]
The origin of the modern 12-string guitar is not clear, but it arose in the closing years of the 19th century. [4] The most likely ancestors using courses of doubled strings are some Mexican instruments of Spanish ancestry such as the bandolón , the guitarra séptima, the guitarra quinta huapanguera, and the bajo sexto. [5] Pictures such as the 1901 Mexican Typical Orchestra at the Pan-American Exposition show a guitar with 12 strings. At the end of the 19th century, the archtop mandolin was one of the first instruments with courses of doubled strings designed in the United States.[ citation needed ]
In the 19th and early 20th centuries, 12-strings were regarded as "novelty" instruments. [6] The 12-string guitar did not become a major part of blues and folk music till the 1920s and the 1930s, when their "larger than life" [5] sound made them ideal as solo accompaniment for vocalists, especially Lead Belly and Blind Willie McTell. [7] The 12-string guitar has since occupied roles in certain varieties of folk, rock, jazz, and popular music. In the 1930s, Mexican-American guitarist and singer Lydia Mendoza popularized the instrument. In the 1950s, Lead Belly's protégé, Fred Gerlach, brought the instrument into the American folk music world. Initially, it was primarily used for accompaniment, owing to the greater difficulty of picking or executing string "bends" on its double-strung courses. The Delta Blues guitar virtuoso Robert Lockwood Jr was presented a handcrafted acoustic 12-string guitar made by an outstanding Japanese luthier in the end of the sixties, and this became the instrument of choice for Lockwood thereafter. In the later 20th century, however, a number of players devoted themselves to producing solo performances on the 12-string guitar, including Leo Kottke, Peter Lang, John McLaughlin, Larry Coryell, Ralph Towner, Robbie Basho, Roger Whittaker, Jack Rose, and James Blackshaw.
Electric 12-strings became a staple in pop and rock music in the 1960s. Early use of the instrument was pioneered by the guitarists of The Wrecking Crew; in 1963, Carol Kaye used a converted Guild six-string on The Crystals' hit "Then He Kissed Me," [8] and on Jackie DeShannon's song "When You Walk in the Room," Glen Campbell played a well-known guitar figure, composed by DeShannon, on an electric 12-string. [9]
One of the first mass-produced electric 12-strings was the Bellzouki. [10] Introduced by Danelectro in 1961, from a design by session guitarist Vinnie Bell, it was initially considered a cross between an electric guitar and a bouzouki rather than an electric version of the traditional 12-string guitar. [11] In the UK in 1963, JMI briefly produced the Vox Bouzouki, later produced in Italy as The Vox Tempest XII, [12] which was used by Vic Flick on the Peter and Gordon hit single "A World Without Love" in 1964. [13] In late 1963, Burns developed the Double Six, [14] supplying a prototype to Hank Marvin of The Shadows, who used it on a number of songs for the soundtrack of the 1964 Cliff Richard movie Wonderful Life; [15] the Double Six was also used on The Searchers' cover version of De Shannon's "When You Walk in the Room."
The electric 12-string gained prominence with the introduction in 1964 of the Rickenbacker 360, [9] made famous through George Harrison's use of it on The Beatles' album A Hard Day's Night and many subsequent recordings. [16] In 1965, inspired by Harrison, Roger McGuinn made the Rickenbacker 12-string central to The Byrds' folk rock sound, further popularising the instrument. [17]
By the mid-1960s, most major guitar manufacturers were producing competing instruments, including the Fender Electric XII (used by Roy Wood of The Move), and the Vox Phantom XII (used by Tony Hicks of The Hollies). [18] Gretsch, Guild, and Gibson also produced electric 12-string models from the mid-Sixties and following decades, [9] with Gretsch promoting theirs by supplying a number of custom made 12-strings for The Monkees guitarist Michael Nesmith, for use on The Monkees TV series. [19]
Standard electric 12-strings became less popular with the end of the American folk rock scene in the late sixties; Fender and Gibson ceased production of the Electric XII and ES-335 12-string variant respectively, in 1969. [20] [21] However, from the 1970s, some progressive rock, hard rock, and jazz fusion guitarists, most notably Jimmy Page of Led Zeppelin, Don Felder of the Eagles, John McLaughlin of The Mahavishnu Orchestra and Alex Lifeson of Rush used double-necked guitars such as the Gibson EDS-1275, with six-string and 12-string necks, for live appearances, allowing easy transition between different sounds mid-song. [22]
The post punk era of the late '70s and early '80s saw a resurgence of electric 12-string guitar use among '60s-influenced alternative rock, pop, and indie guitarists. Players such as Johnny Marr [23] of The Smiths, Dave Gregory of XTC, [24] Susanna Hoffs of The Bangles, [25] Marty Willson-Piper of The Church, [26] Peter Buck of R.E.M., and Tom Petty and Mike Campbell of Tom Petty and the Heartbreakers often chose 12-strings (particularly Rickenbackers) for many songs. [27]
In the 1980s John C Hall, president of Rickenbacker, invited Roger McGuinn to participate in a limited-edition signature model. McGuinn was delighted. Roger McGuinn's signature model Rickenbacker 12-string was introduced in 1988 as the 370/12 RME1. [9]
The strings are placed in courses of two strings each that are usually played together. The two strings in each of the lower four courses are normally tuned an octave apart, while each pair of strings in the top two courses are tuned in unison. The strings are generally arranged such that the higher string of each pair is struck first on a downward strum. However, Rickenbacker usually reverses this arrangement on its electric 12-string guitars. The tuning of the second string in the third course (G) varies. Some players use a unison string, while most prefer the distinctive high-pitched, bell-like quality an octave string makes in this position. Another common variant is to tune the octave string in the sixth (lowest) course two octaves above the lower string, rather than one. Some players, either in search of distinctive tone or for ease of playing, remove some doubled strings. For example, removing the higher octave from the three bass courses simplifies playing running bass lines, but keeps the extra treble strings for the full strums. Some manufacturers have produced 9-string instruments based on this setup, in which either the lower three courses are singular, or the upper three courses are singular. Additionally; some players adapted more unconventional stringing: for example, Big Joe Williams used doubled strings on the 1st, 2nd and 4th courses of his guitars; at first adapted six-string instruments and into the sixties and later usually adapted 12-strings.
The extra tension placed on the instrument by the doubled strings is high, and because of this additional stress on their necks and soundboards, 12-string guitars long had a reputation for warping after a few years of use. (This is less of a problem in modern instruments, built after 1970.) Until the wide spread adoption by American makers of the truss rod after WWII, 12-string guitars were frequently tuned lower than the traditional EADGBE to reduce the stresses on the instrument. For example, Lead Belly often used a low-C tuning, but in some recordings, his tunings can be recognized as low-B and A tunings, partially due to the unusually long scale length (~26.5-27") of the particular models of guitar that he preferred in combination with the heavy strings that were commonly available (14-70). [28] Some 12-string guitars have nontraditional structural supports to prevent or postpone warping, at the expense of appearance and tone.[ citation needed ] To additionally reduce string tension, 12-string guitars built prior to 1970 typically had shorter necks and scale lengths than six-string guitars, which made frets more closely spaced, with some notable exceptions such as the instruments made by the Oscar Schmidt company before their bankruptcy, which usually had scale lengths of around 26.5". Their bridges, especially in acoustic guitars, had a larger reinforcement plate for the same reason, and tailpiece and floating-bridge setups were far more common than on six string instruments as another way to combat the effect of the high tension.
Advances in materials, design, and construction in such guitars made after 1970 have eliminated most of these accommodations. Contemporary 12 string guitars are commonly built to the same dimensions and scale as their six-string counterparts, albeit still usually with heavier build and bracing. [29]
The most common tuning, considered standard today, is a variation on the standard six-string guitar tuning: E3•E2 A3•A2 D4•D3 G4•G3 B3•B3 E4•E4, moving from lowest (sixth) course to highest (first) course. [30] Lead Belly and some other players have doubled the lowest course two octaves above instead of one, producing a third string in unison with the top course, and some stringing the third course in unison as well, and some others all courses except the top in octaves.
Some performers use open tunings and other non-standard guitar tunings on 12-string guitars. Some performers have experimented with tuning the two strings within a course to intervals other than octaves or unisons: jazz guitarists such as Ralph Towner (of Oregon), Larry Coryell, and Philip Catherine have tuned the bass courses of their 12-string guitars to the upper fifths and trebles to the lower fourths instead of octaves and unisons; [31] Michael Gulezian tuned strings in the top two courses to whole-tone intervals (and possibly some of the other strings an octave lower) to achieve a very rich, complex sound. [32] The greater number of strings offers almost endless possibilities.
Nashville Tuning is a way of simulating a 12-string guitar sound, using two six-string guitars playing in unison. This is achieved by replacing the lower four courses on one six-string with the higher octave strings for those four courses from a 12-string set, and tuning these four strings an octave higher than normal tuning for those courses on a six-string. Double-tracking this guitar with the standard-tuned six-string is commonly used in recording studios to achieve a "cleaner" 12-string effect. [33]
Mexican 12-String, also known as requinto style or Sierreño style, are modified 12-string guitars that can approximate the sound of a bajo sexto or bajo quinto and play regional Mexican styles, such as norteño (music of Northern Mexico), Tejano (Tex-Mex), and conjunto (música mexicana-tejana). In a traditional 12-string setup, the lower four strings (E, A, D, and G) have octave pairs, while the top two (B and E) have unison pairs. However, for Regional Mexican styles, all strings are set up with identical unison pairs instead of the traditional octave courses. [34] This configuration yields a resonant timbre reminiscent of the venerable bajo sexto, but adds significantly more tension on the bridge and neck. Furthermore, it usually requires the nut to be modified, the neck compensated, and the bridge to be reinforced. [35]
The 12-string guitar's greater number of strings and higher cumulative string tension complicates playing, in both hands. Fretting chords requires greater force, and the width of the neck and the added string tension combine to make soloing and string-bending challenging. The gap between the dual-string courses is usually narrower than that between the single-string courses of a conventional six-string guitar, so more precision is required with the pick or fingertip when not simply strumming chords. Consequently, the instrument is most commonly used for accompaniment, though several players have taken the time to develop the 12-string guitar as a solo instrument. Flat-picking solos are more frequently seen with electric players, whereas a few acoustic players, such as Leo Kottke, have adapted fingerstyle techniques to the instrument; players such as Ralph Towner have applied classical playing techniques.
Roger McGuinn developed his own style of playing a 12-string guitar. The neck of a Rickenbacker 360/12 12-string guitar is as wide as the 6-string guitar. Solos are therefore easier to play and he used his banjo techniques to play chords. In addition to applying a compressor, this determined the sound of The Byrds. Lead Belly adapted both the traditional, simple strum style and the finger-style method that was becoming popular at the time as well; Blind Willie McTell also played finger-style 12 string.
The bass guitar, electric bass or simply bass 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. The bass guitar most commonly has four strings, though five- and six-stringed models are also relatively popular, and bass guitars with even more strings or courses have been built. Since the mid-1950s, the bass guitar has largely come to replace the double bass in popular music due to its lighter weight, the inclusion of frets in most models, and, most importantly, its design for electric amplification. This is also because the double bass is acoustically compromised for its range in that it is scaled down from the optimal size that would be appropriate for those low notes.
The classical guitar, also known as Spanish guitar, is a member of the guitar family used in classical music and other styles. An acoustic wooden string instrument with strings made of gut or nylon, it is a precursor of the modern steel-string acoustic and electric guitars, both of which use metal strings. Classical guitars derive from instruments such as the lute, the vihuela, the gittern, which evolved into the Renaissance guitar and into the 17th and 18th-century baroque guitar. Today's modern classical guitar was established by the late designs of the 19th-century Spanish luthier, Antonio Torres Jurado.
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.
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.
In musical instrument classification, string instruments or chordophones, are musical instruments that produce sound from vibrating strings when a performer plays or sounds the strings in some manner.
A fret is any of the thin strips of material, usually metal wire, inserted laterally at specific positions along the neck or fretboard of a stringed instrument. Frets usually extend across the full width of the neck. On some historical instruments and non-European instruments, frets are made of pieces of string tied around the neck.
The fingerboard is an important component of most stringed instruments. It is a thin, long strip of material, usually wood, that is laminated to the front of the neck of an instrument. The strings run over the fingerboard, between the nut and bridge. To play the instrument, a musician presses strings down to the fingerboard to change the vibrating length, changing the pitch. This is called stopping the strings. Depending on the instrument and the style of music, the musician may pluck, strum or bow one or more strings with the hand that is not fretting the notes. On some instruments, notes can be sounded by the fretting hand alone, such as with hammer ons, an electric guitar technique.
The Appalachian dulcimer is a fretted string instrument of the zither family, typically with three or four strings, originally played in the Appalachian region of the United States. The body extends the length of the fingerboard, and its fretting is generally diatonic.
The Bajo sexto is a Mexican string instrument from the guitar family with 12 strings in six double courses.
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.
Chorus is an audio effect that occurs when individual sounds with approximately the same time, and very similar pitches, converge. While similar sounds coming from multiple sources can occur naturally, as in the case of a choir or string orchestra, it can also be simulated using an electronic effects unit or signal processing device.
A course, on a stringed musical instrument, is either one string or two or more adjacent strings that are closely spaced relative to the other strings, and typically played as a single string. The strings in each multiple-string course are typically tuned in unison or an octave.
The following outline is provided as an overview of and topical guide to guitars:
A multi-neck guitar is a guitar that has multiple fingerboard necks. They exist in both electric and acoustic versions. Examples of multi-neck guitars and lutes go back at least to the Renaissance.
An acoustic guitar is a musical instrument in the string family. When a string is plucked, its vibration is transmitted from the bridge, resonating throughout the top of the guitar. It is also transmitted to the side and back of the instrument, resonating through the air in the body, and producing sound from the sound hole. While the original, general term for this stringed instrument is guitar, the retronym 'acoustic guitar' – often used to indicate the steel stringed model – distinguishes it from an electric guitar, which relies on electronic amplification. Typically, a guitar's body is a sound box, of which the top side serves as a sound board that enhances the vibration sounds of the strings. In standard tuning the guitar's six strings are tuned (low to high) E2 A2 D3 G3 B3 E4.
The Rickenbacker 360/12 is the Rickenbacker company's 12-string variant of their 360 electric guitar model. Mainly known for producing "jangly" sounds, it was among the first electric 12-string guitars. The 360/12 was given worldwide attention when George Harrison used it on many Beatles recordings, introducing the distinctive new sound of this guitar on "I Call Your Name", which the band recorded in March 1964. In the late 1960s, the company made alternative models such as the Rickenbacker 370/12, which became the favored instrument of Roger McGuinn of the Byrds.
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 introduce one or more tuning techniques, such as:
An eight-string bass guitar is a type of bass guitar with double course strings normally tuned in octaves, with both strings in a course usually played simultaneously. As on a 12-string guitar, this produces a natural chorus effect due to the subtle differences in string pitch.
A nine-string guitar is a guitar with nine strings instead of the commonly used six strings. Such guitars are not as common as the six-string variety, but are used by guitarists to modify the sound or expand the range of their instrument.
The Mexican twelve-string guitar, also known as a requinto-style or Sierreño-style guitar, is a modified twelve-string guitar. It can approximate the sound of a bajo sexto or bajo quinto and play regional Mexican styles, such as norteño, Tejano (Tex-Mex), and conjunto. In a traditional 12-string setup, the lower four strings have octave pairs, while the top two have unison pairs. However, for Regional Mexican styles, all strings are set up with identical unison pairs instead of the traditional octave courses. This configuration yields a resonant timbre reminiscent of the venerable bajo sexto, but adds significantly more tension on the bridge and neck. Furthermore, it usually requires the nut to be modified, the neck compensated, and the bridge to be reinforced. It is unclear why this is claimed as online string tension calculators show that the higher pitch strings on a guitar are the ones at higher tension and therefore unison tuning should reduce the overall tension upon the neck and bridge. This may be a misconception equating the strings thickness with its tension, which is actually a factor of tension, pitch, length and string construction.
