The seven-string guitar adds one additional string to the more common six-string guitar, commonly used to extend the bass range (usually a low B) or also to extend the treble range.


The additional string is added in one of two different ways: by increasing the width of the fingerboard such that the additional string may be fretted by the left hand; or, by leaving the fingerboard unchanged and adding a "floating" bass string. In the latter case, the extra bass string lies next to the existing bass strings, but free of the fingerboard in similar fashion as the archlute and theorbo. Such unfrettable bass strings were historically known as diapasons or bourdons.

The archlute is a European plucked string instrument developed around 1600 as a compromise between the very large theorbo, the size and re-entrant tuning of which made for difficulties in the performance of solo music, and the Renaissance tenor lute, which lacked the bass range of the theorbo. Essentially a tenor lute with the theorbo's neck-extension, the archlute lacks the power in the tenor and the bass that the theorbo's large body and typically greater string length provide.

Theorbo plucked string instrument

The theorbo is a plucked string instrument of the lute family, with an extended neck and a second pegbox. Like a lute, a theorbo has a curved-back sound box with a wooden top, typically with a sound hole, and a neck extending out from the soundbox. As with the lute, the player plucks or strums the strings with one hand while "fretting" the strings with the other hand; pressing the strings in different places on the neck produces different pitches (notes), thus enabling the performer to play chords, basslines and melodies.

Some types of seven-string guitars are specific to certain cultures such as the Russian and Brazilian guitars.

Russian guitar musical instrument

The Russian guitar (sometimes referred to as a "Gypsy guitar") is an acoustic seven-string guitar that was developed in Russia toward the end of the 18th century: it shares most of its organological features with the Spanish guitar, although some historians insist on English guitar ascendancy. It is known in Russian as the semistrunnaya gitara (семиструнная гитара), or affectionately as the semistrunka (семиструнка), which translates to "seven-stringer". These guitars are most commonly tuned to an open G chord as follows: D2 G2 B2 D3 G3 B3 D4. In classical literature, the lowest string (D) occasionally is tuned down to the C.


The history of the seven-string guitar stretches back more than 230 years. During the Renaissance period (c. 1400–1600 CE), the European guitar generally had four courses, each strung with two gut strings, and the pair of strings within each course tuned in unison. By the mid-Baroque period (c. 1600–1750) it more commonly had five courses (still double-strung) and used a variety of tunings, some of them re-entrant. By the early eighteenth century six double-strung courses had become common.

Renaissance European cultural period, 14th to 17th century

The Renaissance is a period in European history, covering the span between the 14th and 17th centuries and marking the transition from the Middle Ages to modernity. The traditional view focuses more on the early modern aspects of the Renaissance and argues that it was a break from the past, but many historians today focus more on its medieval aspects and argue that it was an extension of the middle ages.

Course (music) two or more adjacent strings on a musical instrument

A course, on a stringed musical instrument, is 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 course are typically tuned in unison or an octave. Course may also refer to a single string normally played on its own on an instrument with other multi-string courses, for example the bass (lowest) string on a nine-string baroque guitar.

Unison musical parts sounding at the same pitch

In music, unison is two or more musical parts sounding the same pitch or at an octave interval, usually at the same time.

Up to this point most stringed instruments were strung with gut strings. Around 1800 quality metal-wire strings became widely available. These new strings were more durable, remained in tune better, and—most importantly—produced a louder sound than the traditional gut strings. As use of metal strings became more widely adopted, their greater volume output impelled luthiers to experiment more with single-strung courses on their instruments, and in a relatively short time the modern practice of using six single strings became first common, and then standard.

The changing number of courses in these early guitars may also illustrate an ongoing desire on behalf of players to increase the range of the instrument, a development similar to that gone through by the lute in earlier days. It is likely that all of these factors contributed to the development of the seven-string guitar, which has been around ever since. The seven-string guitar never became as widely accepted in Europe as the six-string instrument, but a number of composers did produce a significant body of work for the seven string. French guitarist Napoleon Coste (1805–1883) composed works with a seven-string guitar specifically in mind. The Italian guitarist Mario Maccaferri (1899–1993) was a celebrated advocate of bass strings (diapasons or bourdons) and also composed for the instrument. [1] By contrast, in Russia the seven-string guitar became widely popular, and entire schools of playing were developed around its use. Despite some brief setbacks in the mid-20th century, during which six-string instruments rose in prominence, the seven-string Russian guitar has remained popular in Russia to this day. [2] In the New World, a guitarra séptima or guitarra sétima—with fourteen strings, strung in seven double courses—has been known in Mexico since at least 1776 (Antonio Vargas). [3] These instruments may still be found in use in Mexico, although the modern six-string instrument has become far more common. Seven-string instruments retain current popularity in parts of South America, notably Brazil, where they became an important instrument in the choro music of the 19th century, which is currently (2015) experiencing a revival. [4]

Choro Brazilian music genre

Choro, also popularly called chorinho, is an instrumental Brazilian popular music genre which originated in 19th century Rio de Janeiro. Despite its name, the music often has a fast and happy rhythm. It is characterized by virtuosity, improvisation and subtle modulations, and is full of syncopation and counterpoint. Choro is considered the first characteristically Brazilian genre of urban popular music. The serenaders who play choros are known as chorões.

The Russian guitar or gypsy guitar is a seven-string acoustic guitar tuned to the open G tuning (DGBDGBD), [5] which arrived or was developed early in the 19th century in Russia, possibly as a development of the cittern, the kobza and the torban. It is known in Russia as the semistrunnaya gitara (семиструнная гитара) or affectionately as the semistrunka (семиструнка).

Among alternative tunings for the guitar, an open G tuning is an open tuning that features the G-major chord; its open notes are selected from the notes of a G-major chord, such as the G-major triad (G,B,D). For example, a popular open-G tuning is

Cittern stringed instrument dating from the Renaissance

The cittern or cithren is a stringed instrument dating from the Renaissance. Modern scholars debate its exact history, but it is generally accepted that it is descended from the Medieval citole. It looks much like the modern-day flat-back mandolin and the modern Irish bouzouki, and is descended from the English Guitar. Its flat-back design was simpler and cheaper to construct than the lute. It was also easier to play, smaller, less delicate and more portable. Played by all classes, the cittern was a premier instrument of casual music-making much as is the guitar today.


The kobza, also called bandurka is a Ukrainian folk music instrument of the lute family, a relative of the Central European mandora. The term kobza however, has also been applied to a number of other Eastern European instruments distinct from the Ukrainian kobza.

Its invention was popularized by Andrei Sychra, who also wrote a method for the guitar, as well as over one thousand compositions, seventy-five of which were republished in the 1840s by Stellovsky, and then again in the 1880s by Gutheil. Some of these were published again in the Soviet Union in 1926. Andrei Sychra in his notation, marks with a number between 1 and 4 where to fret the 7th string with the thumb. Another way that Andrei Sychra took advantage of this guitar's innovation was through natural harmonics. Because of the three strings tuned to D, harmonics could be played in synchronization. [6]

Early instruments used gut, and later silk strings; rarely wire. In the 20th century these instruments commonly used nylon strings, like western classical guitars, though by the last third of the century both nylon-strung "classical" and metal-strung "gypsy" versions of the instrument were both plentiful. Whatever material was used for stringing, the Russian guitar is traditionally played without a pick, using fingers for either strumming or picking. The origins of the 7 string most likely came from the English "guittar" popular in the late 18th century. The added string created an extra dimension for bass notes as well as opening up chord possibilities. The seventh string is also likely to have been influenced by the harp as it is meant to played arpeggiated. [7] It also happens that the open D tuning was a perfect fourth lower than the six string tuning. [8] The open D string tuning of this guitar was convenient for many Russian folk songs and dances that were typically within the major key. Along with the added interval possibilities came new techniques not previously seen with 6th string guitars.

The Russian version of the seven-string guitar has been used by professionals, because of its great flexibility and its sound, but has also been popular with amateurs for accompaniment (especially Russian bards) due to the relative simplicity of some basic chords and the ease of playing alternating bass lines. While greatly popular in Russia and Ukraine, this type of guitar has only recently been generating some interest outside of its traditional homeland.

The earliest music published for a seven-string guitar was in St. Petersburg, Russia, on 15 December 1798. The school was owned by Ignác František Held (1766, Třebechovice pod Orebem, Bohemia – 1816, Brest-Litovsk, Russia).

Standard tuning for the Russian guitar is: D2 G2 B2 D3 G3 B3 D4 with a very common "classical" variant being C2 G2 B2 D3 G3 B3 D4

Other tunings include:


The Brazilian seven-string guitar (Portuguese : violão de sete cordas) is an acoustic guitar used primarily in choro and samba. It was introduced to Brazil in the late 19th century as a steel string guitar. The style of "baixaria" counterpoint and accompaniment technique was developed throughout the 20th century, especially by Dino 7 Cordas and Raphael Rabello. In the early 1980s, guitarist Luiz Otavio Braga had a nylon string version made, and this has become the norm for most contemporary choro musicians such as Yamandu Costa.

The Brazilian seven-string guitar is typically tuned like a classical guitar, but with an additional C below the low E as follows: C2 E2 A2 D3 G3 B3 E4; although some musicians tune the C down to a B resulting in: B1 E2 A2 D3 G3 B3 E4.


Seven-string guitarists are utilized in playing traditional and contemporary "classical" repertoire. These instruments are essentially nylon-strung classical guitars with one extra (usually) bass string, and the tuning is most commonly: B1 E2 A2 D3 G3 B3 E4. Aficionados of the instrument have produced many new arrangements traditionally six-string classical guitar pieces, and the seventh string may be retuned—to C or D, for example—to accommodate these arrangements. The use of this instrument in the classical world, along with other extended range instruments having 8, 9, 10, 11, or more strings, has become common enough that several noted string manufacturers now produce and marked string sets specifically for seven-string classical guitars (La Bella; Pyramid; d'Aquisto; etc.) For example, Napoleon Coste arranged one of Franz Schubert's pieces with vocal accompaniment despite guitars being typically for solo performance at the time.

Mexican (guitarra séptima)

There is a guitar of seven courses with double string guitar, totaling 14 strings, known as guitarra séptima . The instrument is still played in Mexico, though it has become uncommon.

Semi-hollow and hollow body electric guitars

In the United States, the jazz guitarist George Van Eps had a seven-string guitar built for him by Epiphone Guitars in the late 1930s and a signature Gretsch seven-string in the late 60s and early 70s. The Van Eps signature guitar may be the first regular-production seven-string electric guitar. Van Eps tuned his 7th string to A.

Several others began using seven-string guitars after Van Eps, including Bucky Pizzarelli, Howard Alden, Ron Eschete, Chance Russell, and John Pizzarelli, son of Bucky Pizzarelli. [10] Lenny Breau also used seven string instruments, but whereas the other players all used instruments with an added bass string, Breau had at least one instrument in which the seventh string was an added treble string, tuned to the 'A' above the high 'E' string (A4). At the time he began using the high A string, no commercially manufacturered string could withstand being tuned that high, so Breau substituted a piece of monofilament fishing line of appropriate gauge. A year later advances in materials science allowed the La Bella company to begin manufacturing a custom string for Breau's high A. [11]

Seven-string semi-acoustic archtop guitars were used by jazz-guitarist Ralph Patt after he began exploring major-thirds tuning in 1964. [12] [13] [14] Patt's tuning is a regular tuning, in the sense that all of the intervals between its successive open strings are major thirds; in contrast, the standard guitar-tuning has one major-third amid four fourths. [15] Major-thirds tuning has a smaller scope than standard guitar-tuning, [15] [16] and so Patt started using seven-string guitars, which enabled major-thirds tuning to have the E-e' range of the standard tuning. He first experimented with a wide-neck Mango guitar from the 1920s, which he modified to have seven strings in 1963. [17] In 1967 he purchased a seven-string by José Rubio. [16]

The first seven-string electric guitars were built in the "hollowbody" or "semi-hollow" archtop styles, where the guitar has a central resonating chamber, or a central block with resonant chambers on the sides. This gave the guitar the dark woodiness, breath, and richness that is associated with traditional "jazz" tone, but also made prone to feedback at high volumes, making it problematic for rock guitar playing.

Solid body electric guitars

In the early thirties the National String Instrument Corporation offered seven-string versions of their solid-body lap-steel guitars.

A solid body seven-string electric guitar was conceived by guitarist Lenny Breau and built by luthier Kirk Sand, [11] debuting at the 1983 NAMM convention featuring a high A-string (rather than the low A-string of Eps). [18] In 1987, Fender signed an agreement with Alex Gregory to produce a Stratocaster-style guitar that featured a high A-string. A small number of prototypes were made. However the unit was never put into production. [19]

The first mass-produced seven-string was the Ibanez UV7 as a signature model for Steve Vai. It was also used by John Petrucci, Reb Beach and Korn amongst others. [20] Vai was drawn to the idea for much of the same reasons seven-string classical and jazz players were—the extended range the additional string offered. After initial experimentation with a high A, a low B was added as the high A proved to be too prone to breaking. (Kirk Sand and Lenny Breau solved the breaking high A string problem by shortening the scale length to 22.75", Vai's Ibanez is 25.5".) Vai began touring with Whitesnake with a seven-string prototype, and then used the guitars for his 1990 release Passion and Warfare .

The seven-string guitar became prominent when the band Korn featured Ibanez Universe guitars on their 1994 debut album. During the 1990s, manufacturers of 7-strings included Fender's subsidiary Squier and Gibson's subsidiary Epiphone.

In this time many guitarists were introduced to the extended range offered by a seven-string guitar. This was somewhat offset by a growing stigma that a seven-string guitar was a "nu metal" instrument, fit only for heavy riffing. This was ironic as Korn guitarists Munky and Head remember being told in their early days that the seven-string guitar could not be used for riffing, as it was a guitar for technical guitar players. [21]

In the 1990s, several other heavy metal guitarists began using seven-string instruments (notably John Petrucci, Trey Azagthoth, and Erik Rutan), seeing the possibility for detuned riffing while preserving the full upper range of the guitar for solos. However, the seven-string guitar failed to really catch on at this phase in its development, and the Universe model was discontinued briefly in 1995. Historically, Matt Bellamy from Muse had used a custom red Manson seven-string to play just one song, "Citizen Erased", with a AADDGBE tuning (the song was originally recorded on a detuned six-string). However, he later started using new Manson custom seven-strings to play new songs "Supremacy", "Survival" and "Liquid State" on Muse's 2012 The 2nd Law album tour. Dino Cazares uses custom seven-string Ibanez guitars; Christian Olde Wolbers has his own signature Jackson seven-string guitar, Jeff Loomis has a signature model made by Schecter and Stephen Carpenter has several of his own models released by ESP.

Hybrid designs

In the early 2000s, Roger McGuinn (renowned for his skills on the twelve-string guitar and for his long association with The Byrds) worked with C. F. Martin & Company to develop a seven-string folk guitar. McGuinn's guitar (currently being marketed by Martin) is tuned the same as a standard folk guitar with steel strings, but the third (G) string is augmented with a high octave string. Many of McGuinn's notable guitar solos utilize the G string of the twelve-string guitar to perform the main melody, and therefore the Martin seven-string guitar was designed to achieve this extended range playing without the need for doubling all six of the guitar's strings.

In 2010, Inox Guitars has created a mix of the Brazilian Viola caipira and the Russian semistrunka (семиструнка). This instrument has 2 bass strings (as the 6th and 7th strings of the semistrunka) and five treble courses (as the Viola caipira) and it is used in open tuning (GDGDGBD) as a slide guitar.

The 7-string guitar of today is frequently tuned with a lower B on the added seventh string (B1–E2–A2–D3–G3–B3–E4), but other common tunings exist. Many jazz [22] and metal musicians tune in dropped A tuning (A1–E2–A2–D3–G3–B3–E4) for improved bass lines and easier power chords. Choro players usually tune the seventh string up a half-step, to C: C2-E2-A2-D3-G3-B3-E4. The common Russian guitar tunings given above are still in widespread use. And players who prefer an added treble string (instead of an added bass string) usually tune: E2–A2–D3–G3–B3–E4–A4.


Seven-string guitars are used in a variety of musical styles including Classical, Jazz, Rock, Progressive Rock, and Heavy Metal. The Seven-string works well in a band setting, as its lowest note, B1 lines up well with the B0 commonly used for the lowest note of a 5+ string bass. Both the guitar and bass could drop tune as well using a lowest note of A1 and A0 respectively (with the bass this extends the range to the lowest note on a standard piano).

Guitar fretted string instrument

The guitar is a fretted musical instrument that usually has six strings. It is typically played with both hands by strumming or plucking the strings with either a guitar pick or the finger(s)/fingernails of one hand, while simultaneously fretting with the fingers of the other hand. The sound of the vibrating strings is projected either acoustically, by means of the hollow chamber of the guitar, or through an electrical amplifier and a speaker.

Eight-string guitar

An eight-string guitar is a guitar with two more strings than the usual six, or one more than the Russian guitar's seven. Eight-string guitars are less common than six- and seven-string guitars, but they are used by a few classical, jazz, and metal guitarists. The eight-string guitar allows a wider tonal range, or non-standard tunings, or both.

Baritone guitar variation on the standard guitar, with a longer scale length

The baritone guitar is a guitar with a longer scale length, typically a larger body, and heavier internal bracing, so it can be tuned to a lower pitch. Gretsch, Fender, Gibson, Ibanez, ESP Guitars, PRS Guitars, Music Man, Danelectro, Schecter, Jerry Jones Guitars, Burns London and many other companies have produced electric baritone guitars since the 1960s, although always in small numbers due to low popularity. Tacoma, Santa Cruz, Taylor, Martin, Alvarez Guitars and others have made acoustic baritone guitars.

Guitar chord set of notes played on a guitar

In music, a guitar chord is a set of notes played on a guitar. A chord's notes are often played simultaneously, but they can be played sequentially in an arpeggio. The implementation of guitar chords depends on the guitar tuning. Most guitars used in popular music have six strings with the "standard" tuning of the Spanish classical guitar, namely E-A-D-G-B-E' ; in standard tuning, the intervals present among adjacent strings are perfect fourths except for the major third (G,B). Standard tuning requires four chord-shapes for the major triads.

Guitar tunings the assigning of pitches to open strings of guitars

Guitar tunings assign pitches to the open strings of guitars, including acoustic guitars, electric guitars, and classical guitars. Tunings are described by the particular pitches denoted by notes in Western music. By convention, the notes are ordered from lowest-pitched string to highest-pitched.

An extended-range bass is an electric bass guitar with a wider frequency range than a standard-tuned four-string bass guitar.

Outline of guitars Overview of and topical guide to guitars

The following outline is provided as an overview of and topical guide to guitars:

Classical guitar with additional strings

A classical guitar with additional strings is a nylon-string or gut-string classical guitar with more than six strings, in which the additional strings pass over a fingerboard so that they may be "stopped" or fretted with the fingers. These are also known as extended-range guitars, and should not be confused with harp guitars.

Ten-string guitar

There are many varieties of ten-string guitar, including:

Eleven-string alto guitar

The eleven-string alto guitar is an extended-range classical guitar developed by Swedish luthier Georg Bolin in the 1960s.

An augmented tuning is a tuning system for musical instruments that is associated with augmented triads, that is a root note, a major third, and an augmented fifth. The augmented fifth is constructed by stacking the major third with another major third. Consequently, all of the intervals are major thirds.

Major thirds tuning

Among alternative tunings for guitar, a major-thirds tuning is a regular tuning in which each interval between successive open strings is a major third. Other names for major-thirds tuning include major-third tuning, M3 tuning, all-thirds tuning, and augmented tuning. By definition, a major-third interval separates two notes that differ by exactly four semitones.

Regular tuning

Among alternative guitar-tunings, regular tunings have equal musical intervals between the paired notes of their successive open strings.

Ralph Patt United States jazz-guitarist, inventor of major-thirds tuning; geologist specializing in hydrology and consulting on Hanford Site

Ralph Oliver Patt was an American jazz-guitarist who introduced major-thirds tuning. Patt's tuning simplified the learning of the fretboard and chords by beginners and improvisation by advanced guitarists. He invented major-thirds tuning under the inspiration of first the atonal music of Arnold Schoenberg and second the jazz of John Coltrane and Ornette Coleman.

Repetitive tuning

Repetitive tunings are alternative tunings for the guitar. A repetitive tuning begins with a list of notes that is duplicated, either at unison or at higher octaves.
