155-410: The guitar is a stringed musical instrument that is usually fretted (with some exceptions ) 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
310-402: A "bass") is similar in appearance and construction to an electric guitar, but with a longer neck and scale length , and four to six strings. The four-string bass, by far the most common, 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 (E, A, D, and G). The bass guitar is a transposing instrument , as it
465-412: A 12-string guitar, allowing him to incorporate chiming 12-string elements in standard six-string playing. In 1982 Uli Jon Roth developed the "Sky Guitar", with a vastly extended number of frets, which was the first guitar to venture into the upper registers of the violin. Roth's seven-string and "Mighty Wing" guitar features a wider octave range. The bass guitar (also called an "electric bass", or simply
620-495: A British usage of the 1600s referring to the "intense visual hallucinations that can accompany severe alcohol withdrawal". As time went on, the phrase lost the reference to devils and came to mean a state of agitation or depression. By the 1800s in the United States, the term "blues" was associated with drinking alcohol, a meaning which survives in the phrase ' blue law ', which prohibits the sale of alcohol on Sunday. In 1827, it
775-484: A banjo or guitar. Regional styles of country blues varied widely in the early 20th century. The (Mississippi) Delta blues was a rootsy sparse style with passionate vocals accompanied by slide guitar. The little-recorded Robert Johnson combined elements of urban and rural blues. In addition to Robert Johnson, influential performers of this style included his predecessors Charley Patton and Son House . Singers such as Blind Willie McTell and Blind Boy Fuller performed in
930-415: A break; the harmony of this two-bar break, the turnaround, can be extremely complex, sometimes consisting of single notes that defy analysis in terms of chords. Much of the time, some or all of these chords are played in the harmonic seventh (7th) form. The use of the harmonic seventh interval is characteristic of blues and is popularly called the "blues seven". Blues seven chords add to the harmonic chord
1085-567: A center for electric blues from 1948 on, when Muddy Waters recorded his first success, "I Can't Be Satisfied". Chicago blues is influenced to a large extent by Delta blues , because many performers had migrated from the Mississippi region. Howlin' Wolf , Muddy Waters, Willie Dixon and Jimmy Reed were all born in Mississippi and moved to Chicago during the Great Migration. Their style
1240-399: A component of R&B. After World War II, new styles of electric blues became popular in cities such as Chicago , Memphis , Detroit and St. Louis . Electric blues used electric guitars , double bass (gradually replaced by bass guitar ), drums , and harmonica (or "blues harp") played through a microphone and a PA system or an overdriven guitar amplifier . Chicago became
1395-440: A filler strip running down the length and behind the neck, used for strength or to fill the cavity through which the truss rod was installed in the neck. In acoustic guitars, string vibration is transmitted through the bridge and saddle to the body via sound board . The sound board is typically made of tonewoods such as spruce or cedar. Timbers for tonewoods are chosen for both strength and ability to transfer mechanical energy from
1550-450: A flat back, most often with incurved sides." The term is used to refer to a number of chordophones that were developed and used across Europe, beginning in the 12th century and, later, in the Americas. A 3,300-year-old stone carving of a Hittite bard playing a stringed instrument is the oldest iconographic representation of a chordophone, and clay plaques from Babylonia show people playing
1705-427: A guitar with one finger (the bar). Known for its portamento capabilities, gliding smoothly over every pitch between notes, the instrument can produce a sinuous crying sound and deep vibrato emulating the human singing voice. Typically, the strings are plucked (not strummed) by the fingers of the dominant hand, while the steel tone bar is pressed lightly against the strings and moved by the opposite hand. The instrument

The electric guitar has had a major influence on popular culture . The guitar is used in a wide variety of musical genres worldwide. It is recognized as a primary instrument in genres such as blues , bluegrass , country , flamenco , folk , jazz , jota , ska , mariachi , metal , punk , funk , reggae , rock , grunge , soul , acoustic music , disco , new wave , new age , adult contemporary music , and pop , occasionally used as
2015-503: A lute-like instrument which is similar to the guitar. Several scholars cite varying influences as antecedents to the modern guitar. Although the development of the earliest "guitar" is lost to the history of medieval Spain, two instruments are commonly claimed as influential predecessors: the four-string oud and its precursor, the European lute ; the former was brought to Iberia by the Moors in
2170-610: A movement known as the Great Migration . The long boom following World War II induced another massive migration of the African-American population, the Second Great Migration , which was accompanied by a significant increase of the real income of the urban blacks. The new migrants constituted a new market for the music industry. The term race record , initially used by the music industry for African-American music,
2325-456: A note with a frequency in a 7:4 ratio to the fundamental note. At a 7:4 ratio, it is not close to any interval on the conventional Western diatonic scale . For convenience or by necessity it is often approximated by a minor seventh interval or a dominant seventh chord . In melody , blues is distinguished by the use of the flattened third , fifth and seventh of the associated major scale . Blues shuffles or walking bass reinforce
2480-594: A part in early blues, citing Robert Johnson 's " Cross Road Blues " as a "thinly veiled reference to Eleggua , the orisha in charge of the crossroads". However, the Christian influence was far more obvious. The repertoires of many seminal blues artists, such as Charley Patton and Skip James , included religious songs or spirituals. Reverend Gary Davis and Blind Willie Johnson are examples of artists often categorized as blues musicians for their music, although their lyrics clearly belong to spirituals. The blues form
2635-569: A part of ragtime; Handy's signature work was the " Saint Louis Blues ". In the 1920s, the blues became a major element of African American and American popular music, also reaching white audiences via Handy's arrangements and the classic female blues performers. These female performers became perhaps the first African American "superstars", and their recording sales demonstrated "a huge appetite for records made by and for black people." The blues evolved from informal performances in bars to entertainment in theaters. Blues performances were organized by
2790-419: A recording career that began in 1926 and spanned forty years. These recordings were typically labeled " race records " to distinguish them from records sold to white audiences. Nonetheless, the recordings of some of the classic female blues singers were purchased by white buyers as well. These blueswomen's contributions to the genre included "increased improvisation on melodic lines, unusual phrasing which altered
2945-399: A right-handed guitar strung in reverse (the treble strings and bass strings reversed). The problem with doing this is that it reverses the guitar's saddle angle. The saddle is the strip of material on top of the bridge where the strings rest. It is normally slanted slightly, making the bass strings longer than the treble strings. In part, the reason for this is the difference in the thickness of
3100-624: A sample in hip-hop , dubstep , or trap music . The modern word guitar and its antecedents have been applied to a wide variety of chordophones since classical times, sometimes causing confusion. The English word guitar , the German Gitarre , and the French guitare were all adopted from the Spanish guitarra , which comes from the Andalusian Arabic قيثارة ( qīthārah ) and
3255-413: 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 they are associated with a more percussive tone. In Portugal,

#17328694652983410-406: A separate genre arose during the black migration from the countryside to urban areas in the 1920s and the simultaneous development of the recording industry. Blues became a code word for a record designed to sell to black listeners. The origins of the blues are closely related to the religious music of Afro-American community, the spirituals . The origins of spirituals go back much further than
3565-494: A single line repeated four times. However, the most common structure of blues lyrics today was established in the first few decades of the 20th century, known as the "AAB" pattern. This structure consists of a line sung over the first four bars, its repetition over the next four, and a longer concluding line over the last bars. This pattern can be heard in some of the first published blues songs, such as " Dallas Blues " (1912) and " Saint Louis Blues " (1914). According to W.C. Handy ,
3720-428: A slight vibrato technique from pushing the string down harder and softer. "Scalloped" fretboards, where the wood of the fretboard itself is "scooped out" between the frets, allow a dramatic vibrato effect. Fine frets, much flatter, allow a very low string-action , but require that other conditions, such as curvature of the neck, be well-maintained to prevent buzz. The truss rod is a thin, strong metal rod that runs along
3875-494: A sound closer to that of an acoustic guitar with the flip of a switch or knob, rather than switching guitars. Those that combine piezoelectric pickups and magnetic pickups are sometimes known as hybrid guitars. Hybrids of acoustic and electric guitars are also common. There are also more exotic varieties, such as guitars with two , three, or rarely four necks, all manner of alternate string arrangements, fretless fingerboards (used almost exclusively on bass guitars, meant to emulate
4030-463: A wider audience, especially white listeners. In the 1960s and 1970s, a hybrid form called blues rock developed, which blended blues styles with rock music . The term 'Blues' may have originated from "blue devils", meaning melancholy and sadness. An early use of the term in this sense is in George Colman 's one-act farce Blue Devils (1798). The phrase 'blue devils' may also have been derived from
4185-449: Is a cyclic musical form in which a repeating progression of chords mirrors the call and response scheme commonly found in African and African-American music. During the first decades of the 20th century blues music was not clearly defined in terms of a particular chord progression. With the popularity of early performers, such as Bessie Smith , use of the twelve-bar blues spread across
4340-436: Is expected to know his or her way around the instrument. In addition to fretboard inlay, the headstock and soundhole surround are also frequently inlaid. The manufacturer's logo or a small design is often inlaid into the headstock. Rosette designs vary from simple concentric circles to delicate fretwork mimicking the historic rosette of lutes. Bindings that edge the finger and soundboards are sometimes inlaid. Some instruments have
4495-404: Is glued into the corners where the rib meets the top and back. This interior reinforcement provides 5 to 20 mm of solid gluing area for these corner joints. Solid linings are often used in classical guitars, while kerfed lining is most often found in steel-string acoustics. Kerfed lining is also called kerfing because it is scored, or "kerfed"(incompletely sawn through), to allow it to bend with
4650-413: Is notated in bass clef an octave higher than it sounds (as is the double bass) to avoid excessive ledger lines being required below the staff . Like the electric guitar, the bass guitar has pickups and it is plugged into an amplifier and speaker for live performances. Modern guitars can be constructed to suit both left- and right-handed players. Typically the dominant hand is used to pluck or strum
4805-709: Is often associated with solo piano, boogie-woogie was also used to accompany singers and, as a solo part, in bands and small combos. Boogie-woogie style was characterized by a regular bass figure, an ostinato or riff and shifts of level in the left hand, elaborating each chord and trills and decorations in the right hand. Boogie-woogie was pioneered by the Chicago-based Jimmy Yancey and the Boogie-Woogie Trio ( Albert Ammons , Pete Johnson and Meade Lux Lewis ). Chicago boogie-woogie performers included Clarence "Pine Top" Smith and Earl Hines , who "linked

The transition from country blues to urban blues that began in the 1920s was driven by the successive waves of economic crisis and booms that led many rural blacks to move to urban areas, in
5115-461: Is played while sitting, placed horizontally across the player's knees or otherwise supported. The horizontal playing style is called "Hawaiian style". The twelve-string guitar usually has steel strings, and it 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
5270-411: Is strengthened by differing types of internal bracing . Many luthiers consider the top the dominant factor in determining the sound quality. The majority of the instrument's sound is heard through the vibration of the guitar top as the energy of the vibrating strings is transferred to it. The body of an acoustic guitar has a sound hole through which sound projects. The sound hole is usually a round hole in
5425-402: Is the neck-through-body construction. These are designed so that everything from the machine heads down to the bridge is located on the same piece of wood. The sides (also known as wings) of the guitar are then glued to this central piece. Some luthiers prefer this method of construction as they claim it allows better sustain of each note. Some instruments may not have a neck joint at all, having
5580-530: Is the point at which the neck is either bolted or glued to the body of the guitar. Almost all acoustic steel-string guitars, with the primary exception of Taylors, have glued (otherwise known as set) necks, while electric guitars are constructed using both types. Most classical guitars have a neck and headblock carved from one piece of wood, known as a "Spanish heel". Commonly used set neck joints include mortise and tenon joints (such as those used by C. F. Martin & Co.), dovetail joints (also used by C. F. Martin on
5735-528: 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
5890-548: Is used extensively in jazz , blues , R & B , and rock and roll . The first successful magnetic pickup for a guitar was invented by George Beauchamp , and incorporated into the 1931 Ro-Pat-In (later Rickenbacker ) "Frying Pan" lap steel; other manufacturers, notably Gibson , soon began to install pickups in archtop models. After World War II the completely solid-body electric was popularized by Gibson in collaboration with Les Paul , and independently by Leo Fender of Fender Music . The lower fretboard action (the height of
6045-899: Is usually credited to the American Orville Gibson . Lloyd Loar of the Gibson Mandolin-Guitar Mfg. Co introduced the violin-inspired F-shaped hole design now usually associated with archtop guitars, after designing a style of mandolin of the same type. The typical archtop guitar has a large, deep, hollow body whose form is much like that of a mandolin or a violin-family instrument. Nowadays, most archtops are equipped with magnetic pickups, and they 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 . All three principal types of resonator guitars were invented by
6200-421: The viola da mano , a guitar-like instrument of the 15th and 16th centuries, is widely considered to have been the single most important influence in the development of the baroque guitar.

However, in the 1920s, when country blues began to be recorded, the use of the banjo in blues music was quite marginal and limited to individuals such as Papa Charlie Jackson and later Gus Cannon . Blues music also adopted elements from the "Ethiopian airs", minstrel shows and Negro spirituals , including instrumental and harmonic accompaniment. The style also

The last chord is the dominant (V) turnaround , marking the transition to the beginning of the next progression. The lyrics generally end on the last beat of the tenth bar or the first beat of the 11th bar, and the final two bars are given to the instrumentalist as

The original purpose of the resonator was to produce a very loud sound; this purpose has been largely superseded by electrical amplification , but the resonator guitar is still played because of its distinctive tone. Resonator guitars may have either one or three resonator cones. The method of transmitting sound resonance to the cone is either a "biscuit" bridge, made of a small piece of hardwood at
7750-468: The "AAB" pattern was adopted to avoid the monotony of lines repeated three times. The lyrics are often sung in a rhythmic talk style rather than a melody, resembling a form of talking blues . Early blues frequently took the form of a loose narrative. African-American singers voiced their "personal woes in a world of harsh reality: a lost love, the cruelty of police officers, oppression at the hands of white folk, [and] hard times". This melancholy has led to

However, many scholars consider the lute an offshoot or separate line of development which did not influence the evolution of the guitar in any significant way. At least two instruments called "guitars" were in use in Spain by 1200: the guitarra latina (Latin guitar) and

Black and white musicians shared the same repertoire and thought of themselves as " songsters " rather than blues musicians. The notion of blues as
11625-411: The blues, usually dating back to the middle of the 18th century, when the slaves were Christianized and began to sing and play Christian hymns , in particular those of Isaac Watts , which were very popular. Before the blues gained its formal definition in terms of chord progressions, it was defined as the secular counterpart of spirituals. It was the low-down music played by rural blacks. Depending on
11780-479: The boogie-woogie wave and was strongly influenced by big band music. It uses saxophone or other brass instruments and the guitar in the rhythm section to create a jazzy, up-tempo sound with declamatory vocals. Jump blues tunes by Louis Jordan and Big Joe Turner , based in Kansas City, Missouri , influenced the development of later styles such as rock and roll and rhythm and blues. Dallas-born T-Bone Walker , who
11935-429: The constant 17.817—an approximation to 1/(1-1/ 2 12 {\displaystyle {\sqrt[{12}]{2}}} ). If the nth fret is a distance x from the bridge, then the distance from the (n+1)th fret to the bridge is x-(x/17.817). Frets are available in several different gauges and can be fitted according to player preference. Among these are "jumbo" frets, which have a much thicker gauge, allowing for use of
12090-479: The emphasis and impact of the lyrics, and vocal dramatics using shouts, groans, moans, and wails. The blues women thus effected changes in other types of popular singing that had spin-offs in jazz, Broadway musicals , torch songs of the 1930s and 1940s, gospel , rhythm and blues , and eventually rock and roll ." Urban male performers included popular black musicians of the era, such as Tampa Red , Big Bill Broonzy and Leroy Carr . An important label of this era
12245-399: The end of the nineteenth century in the United States, but nylon and steel strings became mainstream only following World War II . The guitar's ancestors include the gittern , the vihuela , the four- course Renaissance guitar , and the five-course baroque guitar , all of which contributed to the development of the modern six-string instrument. There are three main types of modern guitar:
12400-429: The expansion of railroads in the southern United States. Several scholars characterize the development of blues music in the early 1900s as a move from group performance to individualized performance. They argue that the development of the blues is associated with the newly acquired freedom of the enslaved people. According to Lawrence Levine, "there was a direct relationship between the national ideological emphasis upon
12555-428: The exterior surface of a guitar, both for decoration and artistic purposes and, in the case of the markings on the 3rd, 5th, 7th and 12th fret (and in higher octaves), to provide guidance to the performer about the location of frets on the instrument. The typical locations for inlay are on the fretboard, headstock, and on acoustic guitars around the soundhole, known as the rosette . Inlays range from simple plastic dots on
12710-422: The five course guitar. A literary source, Lope de Vega's Dorotea, gives the credit to the poet and musician Vicente Espinel . This claim was also repeated by Nicolas Doizi de Velasco in 1640, however this claim has been contested by others who state that Espinel's birth year (1550) make it impossible for him to be responsible for the tradition. He believed that the tuning was the reason the instrument became known as
12865-434: The five-course baroque guitar , which was documented in Spain from the middle of the 16th century, enjoyed popularity, especially in Spain, Italy and France from the late 16th century to the mid-18th century. In Portugal, the word viola referred to the guitar, as guitarra meant the " Portuguese guitar ", a variety of cittern . There were many different plucked instruments that were being invented and used in Europe during
13020-410: The four first bars, its repetition over the next four, and then a longer concluding line over the last bars. Early blues frequently took the form of a loose narrative, often relating the racial discrimination and other challenges experienced by African-Americans. Many elements, such as the call-and-response format and the use of blue notes, can be traced back to the music of Africa . The origins of
13175-474: The fretboard and accessible through the sound hole. Some truss rods can only be accessed by removing the neck. The truss rod counteracts the immense amount of tension the strings place on the neck, bringing the neck back to a straighter position. Turning the truss rod clockwise tightens it, counteracting the tension of the strings and straightening the neck or creating a backward bow. Turning the truss rod counter-clockwise loosens it, allowing string tension to act on
13330-616: The fretboard and located at exact points that divide the scale length in accordance with a specific mathematical formula. The exceptions include fretless bass guitars and very rare fretless guitars. Pressing a string against a fret determines the strings' vibrating length and therefore its resultant pitch. The pitch of each consecutive fret is defined at a half-step interval on the chromatic scale . Standard classical guitars have 19 frets and electric guitars between 21 and 24 frets, although guitars have been made with as many as 27 frets. Frets are laid out to accomplish an equal tempered division of
13485-448: The fretboard to intricate works of art covering the entire exterior surface of a guitar (front and back). Some guitar players have used LEDs in the fretboard to produce unique lighting effects onstage. Fretboard inlays are most commonly shaped like dots, diamond shapes, parallelograms, or large blocks in between the frets. Dots are usually inlaid into the upper edge of the fretboard in the same positions, small enough to be visible only to
13640-403: The fretboard usually differs from the wood in the rest of the neck. The bending stress on the neck is considerable, particularly when heavier gauge strings are used (see Tuning ), and the ability of the neck to resist bending (see Truss rod ) is important to the guitar's ability to hold a constant pitch during tuning or when strings are fretted. The rigidity of the neck with respect to the body of
13795-534: The fretboard's surface constitutes a segment. The smaller the fretboard radius, the more noticeably curved the fretboard is. Most modern guitars feature a 12" neck radius, while older guitars from the 1960s and 1970s usually feature a 6-8" neck radius. Pinching a string against a fret on the fretboard effectively shortens the vibrating length of the string, producing a higher pitch. Fretboards are most commonly made of rosewood , ebony , maple , and sometimes manufactured using composite materials such as HPL or resin. See
13950-417: The genre took its shape from the idiosyncrasies of individual performers. However, there are some characteristics that were present long before the creation of the modern blues. Call-and-response shouts were an early form of blues-like music; they were a "functional expression ... style without accompaniment or harmony and unbounded by the formality of any particular musical structure". A form of this pre-blues
14105-410: The guitar is one determinant of a good instrument versus a poor-quality one. The cross-section of the neck can also vary, from a gentle "C" curve to a more pronounced "V" curve. There are many different types of neck profiles available, giving the guitarist many options. Some aspects to consider in a guitar neck may be the overall width of the fretboard, scale (distance between the frets), the neck wood,
14260-751: The hell out of me. Hokum blues celebrated both comedic lyrical content and a boisterous, farcical performance style. Tampa Red and Georgia Tom 's " It's Tight Like That " (1928) is a sly wordplay with the double meaning of being " tight " with someone, coupled with a more salacious physical familiarity. Blues songs with sexually explicit lyrics were known as dirty blues . The lyrical content became slightly simpler in postwar blues, which tended to focus on relationship woes or sexual worries. Lyrical themes that frequently appeared in prewar blues, such as economic depression, farming, devils, gambling, magic, floods and drought, were less common in postwar blues. The writer Ed Morales claimed that Yoruba mythology played
14415-403: The hollow body of the guitar, which acts as a resonating chamber . The classical Spanish guitar is often played as a solo instrument using a comprehensive fingerstyle technique where each string is plucked individually by the player's fingers, as opposed to being strummed. The term "finger-picking" can also refer to a specific tradition of folk, blues, bluegrass, and country guitar playing in
14570-454: The huge variety of proto-blues styles, such as field hollers and ring shouts . A record of blues music as it existed before 1920 can also be found in the recordings of artists such as Lead Belly and Henry Thomas . All these sources show the existence of many different structures distinct from twelve- , eight- , or sixteen-bar . The social and economic reasons for the appearance of the blues are not fully known. The first appearance of
14725-434: The individual, the popularity of Booker T. Washington's teachings, and the rise of the blues." Levine stated that "psychologically, socially, and economically, African-Americans were being acculturated in a way that would have been impossible during slavery, and it is hardly surprising that their secular music reflected this as much as their religious music did." There are few characteristics common to all blues music, because
14880-405: The inside of the neck. It is used to correct changes to the neck's curvature caused by aging of the neck timbers, changes in humidity, or to compensate for changes in the tension of strings. The tension of the rod and neck assembly is adjusted by a hex nut or an allen-key bolt on the rod, usually located either at the headstock, sometimes under a cover, or just inside the body of the guitar underneath
15035-586: The low rate of literacy among rural African Americans at the time. Reports of blues music in southern Texas and the Deep South were written at the dawn of the 20th century. Charles Peabody mentioned the appearance of blues music at Clarksdale, Mississippi , and Gate Thomas reported similar songs in southern Texas around 1901–1902. These observations coincide more or less with the recollections of Jelly Roll Morton , who said he first heard blues music in New Orleans in 1902; Ma Rainey , who remembered first hearing
15190-536: The lowest four strings of the six-string guitar, which is the same tuning pitch as an electric bass guitar. It can, more rarely, be found with five or six strings, which provides a wider range of notes to be played with less movement up and down the neck. Electric guitars can have solid, semi-hollow, or hollow bodies; solid bodies produce little sound without amplification. In contrast to a standard acoustic guitar, electric guitars instead rely on electromagnetic pickups , and sometimes piezoelectric pickups, that convert
15345-416: The most important of all guitar makers, Antonio Torres Jurado , who increased the size of the guitar body, altered its proportions, and invented the breakthrough fan-braced pattern. Bracing, the internal pattern of wood reinforcements used to secure the guitar's top and back and prevent the instrument from collapsing under tension, is an important factor in how the guitar sounds. Torres' design greatly improved
15500-561: The most influential designers of their time. Bracing not only strengthens the top against potential collapse due to the stress exerted by the tensioned strings but also affects the resonance characteristics of the top. The back and sides are made out of a variety of timbers such as mahogany, Indian rosewood and highly regarded Brazilian rosewood ( Dalbergia nigra ). Each one is primarily chosen for their aesthetic effect and can be decorated with inlays and purfling. Stringed musical instrument Too Many Requests If you report this error to
15655-516: The music industry during the 1920s and 1930s. Other chord progressions, such as 8-bar forms, are still considered blues; examples include " How Long Blues ", " Trouble in Mind ", and Big Bill Broonzy 's " Key to the Highway ". There are also 16-bar blues , such as Ray Charles 's instrumental "Sweet 16 Bars" and Herbie Hancock 's " Watermelon Man ". Idiosyncratic numbers of bars are occasionally used, such as
15810-585: The neck and creating a forward bow. Adjusting the truss rod affects the intonation of a guitar as well as the height of the strings from the fingerboard, called the action . Some truss rod systems, called double action truss systems, tighten both ways, pushing the neck both forward and backward (standard truss rods can only release to a point beyond which the neck is no longer compressed and pulled backward). The artist and luthier Irving Sloane pointed out, in his book Steel-String Guitar Construction , that truss rods are intended primarily to remedy concave bowing of
15965-414: The neck and sides built as one piece and the body built around it. The fingerboard , also called the fretboard, is a piece of wood embedded with metal frets that comprises the top of the neck. It is flat on classical guitars and slightly curved crosswise on acoustic and electric guitars. The curvature of the fretboard is measured by the fretboard radius, which is the radius of a hypothetical circle of which
16120-470: The neck, but cannot correct a neck with "back bow" or one that has become twisted. Classical guitars do not require truss rods, as their nylon strings exert a lower tensile force with lesser potential to cause structural problems. However, their necks are often reinforced with a strip of harder wood, such as an ebony strip that runs down the back of a cedar neck. There is no tension adjustment on this form of reinforcement. Inlays are visual elements set into
16275-454: The nut, which can adversely affect tuning stability, some guitarists fit a roller nut. Some instruments use a zero fret just in front of the nut. In this case the nut is used only for lateral alignment of the strings, the string height and length being dictated by the zero fret. A guitar's frets , fretboard , tuners , headstock , and truss rod , all attached to a long wooden extension, collectively constitute its neck . The wood used to make
16430-413: The octave. Each set of twelve frets represents an octave. The twelfth fret divides the scale length exactly into two halves, and the 24th fret position divides one of those halves in half again. The ratio of the spacing of two consecutive frets is 2 12 {\displaystyle {\sqrt[{12}]{2}}} ( twelfth root of two ). In practice, luthiers determine fret positions using
16585-502: The others are tuned in octaves. The 12-string guitar is also made in electric forms. The chime-like sound of the 12-string electric guitar was the basis of jangle pop . The acoustic bass guitar is a bass instrument with a hollow wooden body similar to, though usually somewhat larger than, that of a six-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
16740-420: The pitch. The traditional tuner layout is "3+3", in which each side of the headstock has three tuners (such as on Gibson Les Pauls ). In this layout, the headstocks are commonly symmetrical. Many guitars feature other layouts, including six-in-line tuners (featured on Fender Stratocasters ) or even "4+2" (e.g. Ernie Ball Music Man). Some guitars (such as Steinbergers ) do not have headstocks at all, in which case
16895-419: The player. These usually appear on the odd-numbered frets, but also on the 12th fret (the one- octave mark) instead of the 11th and 13th frets. Some older or high-end instruments have inlays made of mother of pearl, abalone, ivory, colored wood or other exotic materials and designs. Simpler inlays are often made of plastic or painted. High-end classical guitars seldom have fretboard inlays as a well-trained player
17050-498: The playing of single-lined melodies. Modern dimensions of the classical instrument were established by the Spaniard Antonio de Torres Jurado (1817–1892). Flat-top guitars with steel strings are similar to the classical guitar , however, the flat-top body size is usually significantly larger than a classical guitar, and has a narrower, reinforced neck and stronger structural design. The robust X-bracing typical of flat-top guitars
17205-489: The propulsive left-hand rhythms of the ragtime pianists with melodic figures similar to those of Armstrong's trumpet in the right hand". The smooth Louisiana style of Professor Longhair and, more recently, Dr. John blends classic rhythm and blues with blues styles. Another development in this period was big band blues. The " territory bands " operating out of Kansas City , the Bennie Moten orchestra, Jay McShann , and
17360-458: The religious community a musician belonged to, it was more or less considered a sin to play this low-down music: blues was the devil's music. Musicians were therefore segregated into two categories: gospel singers and blues singers, guitar preachers and songsters. However, when rural black music began to be recorded in the 1920s, both categories of musicians used similar techniques: call-and-response patterns, blue notes, and slide guitars. Gospel music
17515-430: The roughly classical-sized OO and Parlour to the large Dreadnought (the most commonly available type) and Jumbo . Ovation makes a modern variation, with a rounded back/side assembly molded from artificial materials. Archtop guitars are steel-string instruments in which the top (and often the back) of the instrument are carved from a solid billet, into a curved, rather than flat, shape. This violin-like construction
17670-423: The same fashion as other guitars, although slides are also often used, especially in blues. A steel guitar is any guitar played while moving a polished steel bar or similar hard object against plucked strings. The bar itself is called a "steel" and is the source of the name "steel guitar". The instrument differs from a conventional guitar in that it does not use frets; conceptually, it is somewhat akin to playing
17825-460: The same instrument is often used with steel strings particularly in its role within fado music. The guitar is called viola , or violão in Brazil, where it is often used with an extra seventh string by choro musicians to provide extra bass support. In Mexico, the popular mariachi band includes a range of guitars, from the small requinto to the guitarrón , a guitar larger than a cello, which
17980-456: The savannah, are conspicuously absent. According to the historian Paul Oliver , "the roots of the blues were not to be found in the coastal and forest regions of Africa. Rather... the blues was rooted in ... the savanna hinterland, from Senegambia through Mali, Burkina Faso, Northern Ghana, Niger, and northern Nigeria". Additionally, ethnomusicologist John Storm Roberts has argued that "The parallels between African savanna-belt string-playing and
18135-607: The section "Neck" below for the importance of the length of the fretboard in connection to other dimensions of the guitar. The fingerboard plays an essential role in the treble tone for acoustic guitars. The quality of vibration of the fingerboard is the principal characteristic for generating the best treble tone. For that reason, ebony wood is better, but because of high use, ebony has become rare and extremely expensive. Most guitar manufacturers have adopted rosewood instead of ebony. Almost all guitars have frets, which are metal strips (usually nickel alloy or stainless steel) embedded along
18290-405: The shape of the rib). During final construction, a small section of the outside corners is carved or routed out and filled with binding material on the outside corners and decorative strips of material next to the binding, which is called purfling . This binding serves to seal off the end grain of the top and back. Purfling can also appear on the back of an acoustic guitar, marking the edge joints of
18445-510: The single direct ancestor of the blues. However the call-and-response format can be traced back to the music of Africa . That blue notes predate their use in blues and have an African origin is attested to by "A Negro Love Song", by the English composer Samuel Coleridge-Taylor , from his African Suite for Piano , written in 1898, which contains blue third and seventh notes . The Diddley bow (a homemade one-stringed instrument found in parts of
18600-453: The so-called guitarra morisca (Moorish guitar). The guitarra morisca had a rounded back, a wide fingerboard, and several sound holes. The guitarra Latina had a single sound hole and a narrower neck. By the 14th century the qualifiers "moresca" or "morisca" and "latina" had been dropped, and these two chordophones were simply referred to as guitars. The Spanish vihuela , called in Italian
18755-512: The solo guitar.) 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, also known as "Spanish" guitars, are typically strung with nylon strings, plucked with the fingers, played in
18910-446: The songs "can't be sung without a full heart and a troubled spirit", conditions that have inspired countless blues songs. Though the use of the phrase in African-American music may be older, it has been attested to in print since 1912, when Hart Wand 's " Dallas Blues " became the first copyrighted blues composition. In lyrics, the phrase is often used to describe a depressed mood. Early traditional blues verses often consisted of
19065-406: The sound of a stand-up bass ), 5.1 surround guitar , and such. Solid-body seven-string guitars were popularized in the 1980s and 1990s. Other artists go a step further, by using an eight-string guitar with two extra low strings. Although the most common seven-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
19220-406: The southeastern "delicate and lyrical" Piedmont blues tradition, which used an elaborate ragtime-based fingerpicking guitar technique. Georgia also had an early slide tradition, with Curley Weaver , Tampa Red , "Barbecue Bob" Hicks and James "Kokomo" Arnold as representatives of this style. The lively Memphis blues style, which developed in the 1920s and 1930s near Memphis, Tennessee ,
19375-476: The strings from the fingerboard), lighter (thinner) strings, and its electrical amplification lend the electric guitar to techniques 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 . Some electric guitar models feature piezoelectric pickups, which function as transducers to provide
19530-542: The strings to the air within the guitar body. Sound is further shaped by the characteristics of the guitar body's resonant cavity. In expensive instruments, the entire body is made of wood. In inexpensive instruments, the back may be made of plastic. In an acoustic instrument, the body of the guitar is a major determinant of the overall sound quality. The guitar top, or soundboard, is a finely crafted and engineered element made of tonewoods such as spruce and red cedar . This thin piece of wood, often only 2 or 3 mm thick,
19685-425: The strings. Physical properties of the thicker bass strings require them to be slightly longer than the treble strings to correct intonation . Reversing the strings, therefore, reverses the orientation of the saddle, adversely affecting intonation. The headstock is located at the end of the guitar neck farthest from the body. It is fitted with machine heads that adjust the tension of the strings, which in turn affects
19840-449: 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 . The guitar is classified as a chordophone , meaning the sound is produced by a vibrating string stretched between two fixed points. Historically, a guitar was constructed from wood, with its strings made of catgut . Steel guitar strings were introduced near
19995-424: The strings. This is similar to the violin family of instruments where the dominant hand controls the bow. Left-handed players usually play a mirror image instrument manufactured especially for left-handed players. There are other options, some unorthodox, including learn to play a right-handed guitar as if the player is right-handed or playing an unmodified right-handed guitar reversed. Guitarist Jimi Hendrix played
20150-477: The suggestion of an Igbo origin for blues, because of the reputation the Igbo had throughout plantations in the Americas for their melancholic music and outlook on life when they were enslaved. Other historians have argued that there is little evidence of Sub-Sahelian influence in the blues as "elaborate polyrhythm, percussion on African drums (as opposed to European drums), [and] collective participation" which are characteristic of West-Central African music below
20305-507: The techniques of many blues guitarists are remarkable. The big kora of Senegal and Guinea are played in a rhythmic-melodic style that uses constantly changing rhythms, often providing a ground bass overlaid with complex treble patterns, while vocal supplies a third rhythmic layer. Similar techniques can be found in hundreds of blues records". The lyrics often relate troubles experienced within African American society. For instance Blind Lemon Jefferson 's "Rising High Water Blues" (1927) tells of
20460-430: The top of the guitar under the strings. The air inside the body vibrates as the guitar top and body is vibrated by the strings, and the response of the air cavity at different frequencies is characterized, like the rest of the guitar body, by a number of resonance modes at which it responds more strongly. The top, back and ribs of an acoustic guitar body are very thin (1–2 mm), so a flexible piece of wood called lining
20615-446: The trance-like rhythm and call-and-response, and they form a repetitive effect called a groove . Characteristic of the blues since its Afro-American origins, the shuffles played a central role in swing music . The simplest shuffles, which were the clearest signature of the R&;B wave that started in the mid-1940s, were a three-note riff on the bass strings of the guitar. When this riff
20770-444: The trance-like rhythm and form a repetitive effect known as the groove . Blues music is characterized by its lyrics , bass lines , and instrumentation . Early traditional blues verses consisted of a single line repeated four times. It was only in the first decades of the 20th century that the most common current structure became standard: the AAB pattern , consisting of a line sung over
20925-550: The tuning machines are located elsewhere, either on the body or the bridge. The nut is a small strip of bone , plastic , brass , corian , graphite , stainless steel , or other medium-hard material, at the joint where the headstock meets the fretboard. Its grooves guide the strings onto the fretboard, giving consistent lateral string placement. It is one of the endpoints of the strings' vibrating length. It must be accurately cut, or it can contribute to tuning problems due to string slippage or string buzz. To reduce string friction in
21080-400: The two or three sections of the back. Binding and purfling materials are generally made of either wood or plastic. Body size, shape and style have changed over time. 19th-century guitars, now known as salon guitars, were smaller than modern instruments. Differing patterns of internal bracing have been used over time by luthiers. Torres, Hauser, Ramirez, Fleta, and C. F. Martin were among
21235-476: The type of neck construction (for example, the neck may be glued in or bolted on), and the shape (profile) of the back of the neck. Other types of material used to make guitar necks are graphite ( Steinberger guitars), aluminum ( Kramer Guitars , Travis Bean and Veleno guitars ), or carbon fiber ( Modulus Guitars and ThreeGuitars ). Double neck electric guitars have two necks, allowing the musician to quickly switch between guitar sounds. The neck joint or heel
21390-453: The vertex of the cone (Nationals), or a "spider" bridge, made of metal and mounted around the rim of the (inverted) cone (Dobros). Three-cone resonators always use a specialized metal bridge. The type of resonator guitar with a neck with a square cross-section—called "square neck" or "Hawaiian"—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
21545-453: The vibration of the steel strings into signals , which are fed to an amplifier through a patch cable or radio transmitter . The sound is frequently modified by other electronic devices ( effects units ) or the natural distortion of valves ( vacuum tubes ) or the pre-amp in the amplifier. There are two main types of magnetic pickups, single - and double-coil (or humbucker ), each of which can be passive or active . The electric guitar
21700-584: The volume, tone, and projection of the instrument, and it has remained essentially unchanged since. Guitars are often divided into two broad categories: acoustic and electric guitars . Within each category, there are further sub-categories that are nearly endless in quantity and are always evolving. For example, an electric guitar can be purchased in a six-string model (the most common model) or in seven- or twelve-string formats. An instruments overall design, internal construction and components, wood type or species, hardware and electronic appointments all add to
21855-532: Was a formally trained musician, composer and arranger who helped to popularize the blues by transcribing and orchestrating blues in an almost symphonic style, with bands and singers. He became a popular and prolific composer, and billed himself as the "Father of the Blues"; however, his compositions can be described as a fusion of blues with ragtime and jazz, a merger facilitated using the Cuban habanera rhythm that had long been
22010-504: Was a free-born black woman from Pennsylvania who was working as a schoolteacher in South Carolina, instructing both slaves and freedmen, and wrote that she "came home with the blues" because she felt lonesome and pitied herself. She overcame her depression and later noted a number of songs, such as "Poor Rosy", that were popular among the slaves. Although she admitted being unable to describe the manner of singing she heard, Forten wrote that
22165-399: Was closely related to ragtime , which developed at about the same time, though the blues better preserved "the original melodic patterns of African music". The musical forms and styles that are now considered the blues as well as modern country music arose in the same regions of the southern United States during the 19th century. Recorded blues and country music can be found as far back as
22320-471: Was developed in the 1840s by German-American luthiers, of whom Christian Friedrich "C. F." Martin is the best known. Originally used on gut-strung instruments, the strength of the system allowed the later guitars to withstand the additional tension of steel strings. Steel strings produce a brighter tone and a louder sound. The acoustic guitar is used in many kinds of music including folk, country, bluegrass, pop, jazz, and blues. Many variations are possible from
22475-457: Was heard in slave ring shouts and field hollers , expanded into "simple solo songs laden with emotional content". Blues has evolved from the unaccompanied vocal music and oral traditions of slaves imported from West Africa and rural blacks into a wide variety of styles and subgenres, with regional variations across the United States. Although blues (as it is now known) can be seen as a musical style based on both European harmonic structure and
22630-416: Was in 1908. Blues has since evolved from unaccompanied vocal music and oral traditions of slaves into a wide variety of styles and subgenres. Blues subgenres include country blues , Delta blues and Piedmont blues , as well as urban blues styles such as Chicago blues and West Coast blues . World War II marked the transition from acoustic to electric blues and the progressive opening of blues music to
22785-440: Was in the sense of a sad state of mind that John James Audubon wrote to his wife that he "had the blues". In Henry David Thoreau 's book Walden , he mentions "the blues" in the chapter reflecting on his time in solitude.
