Guitars are recognized as one of the primary instruments in jazz, blues, country, flamenco, mariachi, rock music, and many forms of pop. They can also be 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 1930s 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. There are many brands of guitars, but some commonly known brands are PRS, Gibson, Dean, Gretsch, Ibanez, Martin, Jackson, Schecter, and Fender.
HISTORY
Before the development of the electric guitar and the use of synthetic materials, a guitar was defined as being an instrument having "a long, fretted neck, flat wooden soundboard, ribs, and a flat back, most often with incurved sides".[1] Instruments similar to the guitar have been popular for at least 4,000 years. While today's classical guitar first appeared in Spain, it was itself a product of the long and complex history that saw a number of related guitar types developed and used across Europe.[2] The roots of the guitar can be traced back thousands of years to an Indo-European origin in instruments, then known in central Asia and India. For this reason the guitar itself is distantly related to instruments such as the tanbur and setar, and the Indian sitar. The oldest known iconographic representation of an instrument displaying all the essential features of a guitar being played is a 3,300 year old stone carving of a Hittite bard.[3] The modern word, guitar, was adopted into English from Spanish guitarra (German Gitarre, French Guitare),[4] loaned from the medieval Andalusian Arabic qitara[5], itself derived from the Latin cithara, which in turn came from the earlier Greek word kithara,[6] which is descended from the Old Persian word sihtar.[7]

The modern guitar is descended from the Roman cithara brought by the Romans to Hispania around 40 AD, and further adapted and developed with the arrival of the four-string oud, brought by the Moors after their conquest of the Iberian peninsula in the 8th century.[8] Elsewhere in Europe, the indigenous six-string Scandinavian lut (lute), had gained in popularity in areas of Viking incursions across the continent. Often depicted in carvings c. 800 AD, the Norse hero Gunther (also known as Gunnar), played a lute with his toes as he lay dying in a snake-pit, in the legend of Siegfried.[9] By 1200 AD, the four string "guitar" had evolved into two types: the guitarra morisca (Moorish guitar) which had a rounded back, wide fingerboard and several soundholes, and the guitarra latina (Latin guitar) which resembled the modern guitar with one soundhole and a narrower neck.[10]
The Spanish vihuela or "viola da mano", a guitar-like instrument of the 15th and 16th centuries is, due to its similarities, is often considered an important influence in the development of the modern guitar. It had lute-style tuning and a guitar-like body. Its construction had as much in common with the modern guitar as with its contemporary four-course renaissance guitar. The vihuela enjoyed only a short period of popularity; the last surviving publication of music for the instrument appeared in 1576. It is not clear whether it represented a transitional form or was simply a design that combined features of the Arabic oud and the European lute. In favor of the latter view, the reshaping of the vihuela into a guitar-like form can be seen as a strategy of differentiating the European lute visually from the Moorish oud. Meanwhile, the five string renassance guitar and the baroque guitar enjoyed popularity, especially in Italy and France, and indeed, much of Europe from the 15th to the 18th centuries.
The Vinaccia family of luthiers is known for developing the mandolin, and may have built the oldest surviving six string guitar. Gaetano Vinaccia (1759 – after 1831)[11] has his signature on the label of a guitar built in Naples, Italy for six strings with the date of 1779.[12][13] This guitar has been examined and does not show tell-tale signs of modifications from a double-course guitar although fakes are known to exist of guitars and identifying labels from that period.
The dimensions of the modern classical guitar (also known as the Spanish guitar) were established by Antonio Torres Jurado (1817-1892), working in Seville in the 1850s. Torres and Louis Panormo of London (active 1820s-1840s) were both responsible for demonstrating the superiority of fan strutting over transverse table bracing.[14]
Types Of guitar
Acoustic guitars
An acoustic guitar is one not dependent on an external device to be heard but uses a soundboard which is a wooden piece mounted on the front of the guitar's body. The acoustic guitar is quieter than other instruments commonly found in bands and orchestras so when playing within such groups it is often externally amplified. Many acoustic guitars available today feature a variety of pickups which enable the player to amplify and modify the raw guitar sound.
There are several notable subcategories within the acoustic guitar group: classical and flamenco guitars; steel string guitars, which include the flat top or "folk" guitar; twelve string guitars and the arch top guitar. The acoustic guitar group also includes unamplified guitars designed to play in different registers such as the acoustic bass guitar which has a similar tuning to that of the electric bass guitar.
Renaissance and Baroque guitars
These are the gracile ancestors of the modern classical guitar. They are substantially smaller and more delicate than the classical guitar, and generate a much quieter sound. The strings are paired in courses as in a modern 12 string guitar, but they only have four or five courses of strings rather than six. They were more often used as rhythm instruments in ensembles than as solo instruments, and can often be seen in that role in early music performances. (Gaspar Sanz' Instrucción de Música sobre la Guitarra Española of 1674 constitutes the majority of the surviving solo corpus for the era.) Renaissance and Baroque guitars are easily distinguished because the Renaissance guitar is very plain and the Baroque guitar is very ornate, with ivory or wood inlays all over the neck and body, and a paper-cutout inverted "wedding cake" inside the hole.
Classical guitars
These are typically strung with nylon strings, played in a seated position and are used to play a diversity of musical styles including classical music. The classical guitar's wide, flat neck allows the musician to play scales, arpeggios and certain chord forms more easily and with less adjacent string interference than on other styles of guitar. Flamenco guitars are very similar in construction, but are associated with a more percussive tone. In Mexico, the popular mariachi band includes a range of guitars, from the tiny requinto to the guitarron, a guitar larger than a cello, which is tuned in the bass register. In Colombia, the traditional quartet includes a range of instruments too, from the small bandola (sometimes known as the Deleuze-Guattari, for use when traveling or in confined rooms or spaces), to the slightly larger tiple, to the full sized classical guitar. The requinto also appears in other Latin-American countries as a complementary member of the guitar family, with its smaller size and scale, permitting more projection for the playing of single-lined melodies. Modern dimensions of the classical instrument were established by Antonio Torres Jurado (1817-1892). Classical guitars are sometimes referred to as classic guitars. In recent years, the series of guitars used by the Niibori Guitar orchestra have gained some currency, namely:
* Sopranino guitar (an octave and a fifth higher than normal); sometimes known as the piccolo guitar
* Soprano guitar (an octave higher than normal)
* Alto guitar (a 5th higher than normal)
* Prime (ordinary classical) guitar
* Niibori bass guitar (a 4th lower than normal); Niibori simply calls this the "bass guitar", but this assigns a different meaning to the term than other parts of the community use, as his is only a 4th lower, and has 6 strings
* Contrabass guitar (an octave lower than normal)
The modern Ten-string guitar
The Modern/Yepes 10-string guitar (a classical guitar) adds four strings (resonators) tuned in such a way that they (along with the other three bass strings) can resonate in unison with any of the 12 chromatic notes that can occur on the higher strings; the idea behind this being an attempt at enhancing and balancing sonority.

Portuguese guitar
In spite of the name, it is not a guitar, but rather a cittern.

Flat-top (steel-string) guitars
Similar to the classical guitar, however, within the varied sizes of the steel-stringed guitar the body size is usually significantly larger than a classical guitar and it has a narrower, reinforced neck and stronger structural design. This allows the instrument to withstand the additional tension of steel strings. The steel strings produce a brighter tone, and according to many players, a louder sound. The acoustic guitar is used in many kinds of music including folk, country, bluegrass, pop, jazz and blues.
Archtop guitars
These are steel string instruments in which the top (and often the back) of the instrument are carved in a curved rather than a flat shape. Lloyd Loar of the Gibson Guitar Corporation introduced the violin-inspired f-hole design now usually associated with archtop guitars, after designing a style of mandolin of the same type. The typical archtop is a deep, hollow body guitar whose form is much like that of a mandolin or violin family instrument. Nowadays, most archtops are equipped with magnetic pickups and are therefore both acoustic and electric. F-hole archtop guitars were immediately adopted upon their release by both jazz and country musicians and have remained particularly popular in jazz music, usually with flatwound strings.
Resonator, resophonic or Dobro guitars
Similar to the flat top guitar in appearance, the sound of the resonator guitar is produced by a metal resonator mounted in the middle of the top. The physical principle of the guitar is therefore similar to the banjo. The original purpose of the resonator was to amplify the sound of the guitar. This purpose has been largely superseded by electrical amplification, but the resonator guitar is still played because of its distinctive sound. Resonator guitars may have either one resonator cone or three resonator cones. Three-cone resonators have two cones on the left above one another and one cone immediately to the right. The method of transmitting sound resonance to the cone is either a "biscuit" bridge, made of a small piece of hardwood, or a "spider" bridge, made of metal and larger in size. Three-cone resonators always use a specialized metal spider bridge. The type of resonator guitar with a neck with a square cross-section – called "square neck" – is usually played face up, on the lap of the seated player, and often with a metal or glass slide. The round neck resonator guitars are normally played in the same fashion as other guitars, although slides are also often used, especially in blues.
12 string guitars
The twelve string guitar usually has steel strings and is widely used in folk music, blues and rock and roll. Rather than having only six strings, the 12-string guitar has six courses made up of two strings each, like a mandolin or lute. The highest two courses are tuned in unison, while the others are tuned in octaves. The 12-string guitar is also made in electric forms.
Russian guitars
These are seven string acoustic guitars which were the norm for Russian guitarists throughout the 19th and well into the 20th centuries. The guitar is traditionally tuned to an open G major tuning.
Acoustic bass guitars
Have steel strings or gut strings and often the same tuning as an electric bass guitar.
Tenor guitars
A number of classical guitarists call the Niibori prime guitar a "Tenor Guitar" on the grounds that it sits in pitch between the alto and the bass. Elsewhere[citation needed]the name is taken for a 4-string guitar with a scale length of 23" (585 mm) – about the same as a Terz Guitar. The tenor guitar is tuned in fifths, C G D A, as is the tenor banjo and the cello. It is generally accepted[citation needed] that the tenor guitar was created to allow a tenor banjo player to follow the fashion as it evolved from Dixieland Jazz towards the more progressive Jazz that featured guitar. It allows a tenor banjo player to provide a guitar-based rhythm section with little to learn. A small minority of players (such as Nick Reynolds of the Kingston Trio) close tuned the instrument to D G B E to produce a deep instrument that could be played with the 4-note chord shapes found on the top 4 strings of the guitar or ukulele. The deep pitch warrants the wide-spaced chords that the banjo tuning permits, and the close tuned tenor does not have the same full, clear sound.
Harp guitars
Harp Guitars are difficult to classify as there are many variations within this type of guitar. They are typically rare and uncommon in the popular music scene. Most consist of a regular guitar, plus additional 'harp' strings strung above the six normal strings. The instrument is usually acoustic and the harp strings are usually tuned to lower notes than the guitar strings, for an added bass range. Normally there is neither fingerboard nor frets behind the harp strings. Some harp guitars also feature much higher pitch strings strung below the traditional guitar strings. The number of harp strings varies greatly, depending on the type of guitar and also the player's personal preference (as they have often been made to the player's specification).[15] The Pikasso guitar; 4 necks, 2 sound holes, 42 strings] and also the Oracle Harp Sympitar; 24 strings (with 12 sympathetic strings protruding through the neck) are modern examples.
Extended-range guitars
For well over a century guitars featuring seven, eight, nine, ten or more strings have been used by a minority of guitarists as a means of increasing the range of pitch available to the player. Usually, it is bass strings that are added. Classical guitars with an extended range are useful for playing lute repertoire, some of which was written for lutes with more than six courses.
Guitar battente
The battente is smaller than a classical guitar, usually played with four or five metal strings. It is mainly used in Calabria (a region in southern Italy) to accompany the voice.
Electric guitars
Electric guitars can have solid, semi-hollow, or hollow bodies, and produce little sound without amplification. Electromagnetic pickups convert the vibration of the steel strings into electrical signals, which are fed to an amplifier through a cable or radio transmitter. The sound is frequently modified by other electronic devices or the natural distortion of valves (vacuum tubes) in the amplifier. There are two main types of pickup, single and double coil (or humbucker), each of which can be passive or active. The electric guitar is used extensively in jazz, blues, and rock and roll, and was commercialized by Gibson in collaboration with Les Paul, and independently by Leo Fender of Fender Music. The lower fretboard action (the height of the strings from the fingerboard), lighter (thinner) strings, and its electrical amplification lend the electric guitar to some techniques which are less frequently used on acoustic guitars. These include tapping, extensive use of legato through pull-offs and hammer-ons (also known as slurs), pinch harmonics, volume swells, and use of a tremolo arm or effects pedals.
Seven-strings were popularized in the 1980s and 1990s in part due to the release of the Ibanez Universe guitar, endorsed by Steve Vai. Other artists go a step further, by using an 8 string guitar with two extra low strings. Although the most common 7-string has a low B string, Roger McGuinn (of The Byrds and Rickenbacker) uses an octave G string paired with the regular G string as on a 12 string guitar, allowing him to incorporate chiming 12 string elements in standard 6 string playing. in 1982 Uli Jon Roth developed the "Sky Guitar", with a vastly extended amount of frets, which was the first guitar to venture into the upper registers of the violin. Roth's 7-string "Mighty Wing" guitar features an altogether 6-octave range.
The electric bass guitar is similar in tuning to the traditional double bass viol. Hybrids of acoustic and electric guitars are also common. There are also more exotic varieties, such as guitars with two, three,[16] or rarely four necks, all manner of alternate string arrangements, fretless fingerboards (used almost exclusively on bass guitars, meant to emulate the sound of a stand-up bass), 5.1 surround guitar, and such.
Some electric guitar and electric bass guitar models feature Piezoelectric pickups, which function as transducers to provide a sound closer to that of an acoustic guitar with the flip of a switch or knob, rather than switching guitars.
