The Guitar may refer to: The guitar , the musical instrument The Guitar (film) , a 2008 film starring Saffron Burrows "The Guitar" (The Lion Sleeps Tonight) , a song and EP by They Might Be Giants See also [ edit ] Guitar (disambiguation) Topics referred to by

218-410: A jaw harp , shepherd's whistle , nose whistle , nose flute . The nose blows air through an open nosepiece, into an air duct, and across an edge adjacent to the open mouth, creating the resonator. The volume and shape of the mouth cavity augments the pitch of the tone. Helmholtz resonance is also used in bass-reflex speaker enclosures, with the compliance of the air mass inside the enclosure and

327-427: A " jazz guitar ". The tone of an acoustic guitar is produced by the strings' vibration, amplified by 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

436-402: 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

545-413: 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

654-456: A Helmholtz resonator augments the amplitude of the vibratory motion of the enclosed air in a chamber by taking energy from sound waves passing in the surrounding air. In the other definition the sound waves are generated by a uniform stream of air flowing across the open top of an enclosed volume of air. It can be shown that the resonant angular frequency is given by: where: For cylindrical or rectangular necks, we have: where: thus: From

763-407: A Helmholtz resonator with low Q factor , amplifying many frequencies, resulting in the "sounds of the sea". The term Helmholtz resonator is now more generally applied to include bottles from which sound is generated by blowing air across the mouth of the bottle. In this case the length and diameter of the bottle neck also contribute to the resonance frequency and its Q factor . By one definition

872-440: 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

981-410: A guitar amp have played a key role in the development of blues and rock music , both as an accompaniment instrument (playing riffs and chords ) and performing guitar solos , and in many rock subgenres, notably heavy metal music and punk rock . 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

1090-477: A guitar was constructed from wood, with its strings made of catgut . Steel guitar strings were introduced near 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

1199-427: 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

1308-555: A larger version of the contemporary four-course guitars. The vihuela enjoyed only a relatively short period of popularity in Spain and Italy during an era dominated elsewhere in Europe by the lute ; the last surviving published music for the instrument appeared in 1576. Meanwhile, 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

1417-477: A modern 12-string guitar , but they only have four or five courses of strings rather than six single strings normally used now. 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 's Instrucción de Música sobre la Guitarra Española of 1674 contains his whole output for the solo guitar.) Renaissance and Baroque guitars are easily distinguished, because

1526-416: 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 a sample in hip-hop , dubstep , or trap music . The modern word guitar and its antecedents have been applied to

1635-442: A resonator to the ear, most of the tones produced in the surrounding air will be considerably damped; but if the proper tone of the resonator is sounded, it brays into the ear most powerfully…. The proper tone of the resonator may even be sometimes heard cropping up in the whistling of the wind, the rattling of carriage wheels, the splashing of water." A set of varied size resonators was sold to be used as discrete acoustic filters for

1744-402: 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

1853-464: 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 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

1962-469: 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 the abundant nature of sub-categories and its unique tonal & functional property. Acoustic guitars form several notable subcategories within the acoustic guitar group: classical and flamenco guitars ; steel-string guitars, which include

2071-428: 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

2180-477: A slightly open single car window makes a very loud sound, also called side window buffeting or wind throb. Because cars have a large volume, the frequency of the wind throb is quite low. Helmholtz resonance finds application in internal combustion engines (see Airbox ) , subwoofers and acoustics . Intake systems described as 'Helmholtz Systems' have been used in the Chrysler V10 engine built for both

2289-496: 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

2398-472: A specific tradition of folk, blues, bluegrass, and country guitar playing in the United States. Electric guitars , first patented in 1937, use a pickup and amplifier that made the instrument loud enough to be heard, but also enabled manufacturing guitars with a solid block of wood needing a resonant chamber. A wide array of electronic effects units became possible including reverb and distortion (or "overdrive") . Solid-body guitars began to dominate

2507-429: A stream of air in the " tone variator " invented by William Stern , 1897. When air is forced into a cavity, the pressure inside increases. When the external force pushing the air into the cavity is removed, the higher-pressure air inside will flow out. Due to the inertia of the moving air the cavity will be left at a pressure slightly lower than the outside, causing air to be drawn back in. This process repeats, with

2616-788: 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 the Latin cithara , which in turn came from the Ancient Greek κιθάρα which is of uncertain ultimate origin. Kithara appears in

2725-451: Is different from Wikidata All article disambiguation pages All disambiguation pages guitar 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

2834-436: 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

2943-413: Is fundamental in various fields, including acoustics, engineering, and physics. The resonator itself, termed a Helmholtz resonator , consists of two key components: a cavity and a neck. The size and shape of these components are crucial in determining the resonant frequency, which is the frequency at which the system naturally oscillates. In the context of acoustics, Helmholtz resonance is instrumental in

3052-404: 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

3161-413: 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

3270-402: 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 is tuned in the bass register. In Colombia, the traditional quartet includes a range of instruments too, from the small bandola (sometimes known as

3379-462: 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

3488-411: 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

3597-402: 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

3706-420: 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 the roughly classical-sized OO and Parlour to

3815-530: 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

3924-548: 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

4033-517: 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 a lute-like instrument which is similar to the guitar. Several scholars cite varying influences as antecedents to

4142-424: The loudspeaker . 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

4251-403: The 16th century, the five-course guitar was established. It was not a straightforward process. There were two types of five-course guitars, differing in the location of the major third and in the interval pattern. The fifth course can be inferred because the instrument was known to play more than the sixteen notes possible with four. The guitar's strings were tuned in unison, so, in other words, it

4360-897: 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

4469-464: The Bible four times (1 Cor. 14:7, Rev. 5:8, 14:2, and 15:2), and is usually translated into English as harp . The origins of the modern guitar are not known. 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." The term

4578-498: The D-28 and similar models) and Spanish heel neck joints, which are named after the shoe they resemble and commonly found in classical guitars. All three types offer stability. Bolt-on necks, though they are historically associated with cheaper instruments, do offer greater flexibility in the guitar's set-up, and allow easier access for neck joint maintenance and repairs. Another type of neck, only available for solid-body electric guitars,

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

4796-568: The Dodge Viper and the Ram pickup truck, and several of the Buell tube-frame series of motorcycles. The theory of Helmholtz resonators is used in motorcycle and car exhausts to alter the sound of the exhaust note and for differences in power delivery by adding chambers to the exhaust. Exhaust resonators are also used to reduce potentially loud engine noise where the dimensions are calculated so that

4905-580: 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 a seated position and are used to play a diversity of musical styles including classical music . The classical guitar's wide, flat neck allows

5014-559: The Sensations of Tone an apparatus able to pick out specific frequencies from a complex sound . The Helmholtz resonator , as it is now called, consists of a rigid container of a known volume, nearly spherical in shape, with a small neck and hole in one end and a larger hole in the other end to emit the sound. When the resonator's 'nipple' is placed inside one's ear, a specific frequency of the complex sound can be picked out and heard clearly. In his book Helmholtz explains: When we "apply

5123-557: The Slovak-American John Dopyera (1893–1988) for the National and Dobro ( Do pyera Bro thers) companies. Similar to the flat top guitar in appearance, but with a body that may be made of brass, nickel-silver, or steel as well as wood, the sound of the resonator guitar is produced by one or more aluminum resonator cones mounted in the middle of the top. The physical principle of the guitar is therefore similar to

5232-503: 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 was developed in the 1840s by German-American luthiers, of whom Christian Friedrich "C. F." Martin

5341-419: The Spanish guitar. All of these nations even imitated the five-course guitar by "recreating" their own. Finally, c.  1850 , the form and structure of the modern guitar were developed by different Spanish makers such as Manuel de Soto y Solares and, perhaps the most important of all guitar makers, Antonio Torres Jurado , who increased the size of the guitar body, altered its proportions, and invented

5450-444: The air within the cavity to resonate. This phenomenon is characterized by its sharp and high-amplitude resonance curve, making it distinct from other types of acoustic resonance. Since its conceptualization in the 19th century, Helmholtz resonance has continued to be a subject of study and application, illustrating the interplay between simple physical systems and complex vibrational phenomena. Helmholtz described in his 1862 book On

5559-416: The airplane; the honeycomb is just under it. The thickness of the perforated sheet is of importance, as shown above. Sometimes there are two layers of liners; they are then called "2-DOF liners" (DOF meaning degrees of freedom), as opposed to "single DOF liners". This effect might also be used to reduce skin friction drag on aircraft wings by 20%. Vitruvius , a 1st-century B.C. Roman architect, described

5668-403: The baroque guitar. It had six courses (usually), lute-like tuning in fourths and a guitar-like body, although early representations reveal an instrument with a sharply cut waist. It was also larger than the contemporary four-course guitars. By the 16th century, the vihuela's construction had more in common with the modern guitar, with its curved one-piece ribs, than with the viols, and more like

5777-628: 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 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

5886-430: 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

5995-408: The definition of mass density ( ρ {\displaystyle {\rho }} ): V n m = 1 ρ {\displaystyle {\frac {V_{n}}{m}}={\frac {1}{\rho }}} . The speed of sound in a gas is given by: thus, the resonance frequency is: The length of the neck appears in the denominator because the inertia of the air in

6104-423: The design and analysis of musical instruments, architectural acoustics , and sound engineering. It is also utilized in automotive engineering for noise reduction and in designing exhaust systems. The underlying principle involves the vibration of the air mass in the neck of the resonator, acting analogously to a mass on a spring. When external forces, such as airflow, disturb this air mass, it oscillates and causes

6213-459: The development of the modern six-string instrument. There are three main types of modern guitar: the classical guitar (Spanish guitar); the steel-string acoustic guitar or electric guitar ; and the Hawaiian guitar (played across the player's lap). Traditional acoustic guitars include the flat top guitar (typically with a large sound hole) or the archtop guitar , which is sometimes called

6322-476: The exact shape of the hole, the relative thickness of the sheet with respect to the size of the hole and the size of the cavity, this formula can have limitations. More sophisticated formulae can still be derived analytically, with similar physical explanations (although some differences matter). Furthermore, if the mean flow over the resonator is high (typically with a Mach number above 0.3), some corrections must be applied. Helmholtz resonance sometimes occurs when

6431-429: 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

6540-413: The fingers of the opposite hand. A guitar pick may also be used to strike the strings. The sound of the guitar is projected either acoustically , by means of a resonant hollow chamber on the guitar, or amplified by an electronic pickup and an amplifier . The guitar is classified as a chordophone , meaning the sound is produced by a vibrating string stretched between two fixed points. Historically,

6649-516: The flat-topped, or "folk", guitar; twelve-string guitars ; and the arched-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 are the ancestors of the modern classical and flamenco guitar . They are substantially smaller, more delicate in construction, and generate less volume. The strings are paired in courses as in

6758-430: The flow of gasses that were being used to seal the edges of their diffusers as part of their exhaust blow diffuser systems. Helmholtz resonators are also used to build acoustic liners for reducing the noise of aircraft engines, for example. These acoustic liners are made of two components: Such acoustic liners are used in most of today's aircraft engines. The perforated sheet is usually visible from inside or outside

6867-474: 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

6976-616: 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

7085-448: 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

7194-403: 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

7303-534: 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

7412-410: 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,

As with acoustic guitars, there are a number of types of electric guitars, including hollowbody guitars , archtop guitars (used in jazz guitar , blues and rockabilly ) and solid-body guitars , which are widely used in rock music . The loud, amplified sound and sonic power of the electric guitar played through

7630-405: 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

7739-399: The instrument. The West African djembe is related to a Helmholtz resonator with a small neck area, giving it a deep bass tone, but its stretched skin, strongly coupled to the cavity makes it a more complex, and musically interesting, resonant system. It has been in use for thousands of years. Conversely, the human mouth is effectively a Helmholtz resonator when it is used in conjunction with

7848-403: 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 is usually credited to

7957-463: 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 the Middle Ages. By the 16th century, most of the forms of guitar had fallen off, to never be seen again. However, midway through

8066-536: 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

8175-421: 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 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

8284-410: The magnitude of the pressure oscillations increasing and decreasing asymptotically after the sound starts and stops. The port (the neck of the chamber ) is placed in the ear, allowing the experimenter to hear the sound and to determine its loudness. The resonant mass of air in the chamber is set in motion through the second hole, which is larger and doesn't have a neck. A gastropod seashell can form

8393-550: 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 the 8th century. It has often been assumed that the guitar is a development of the lute, or of the ancient Greek kithara. However, many scholars consider

8502-540: 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. Helmholtz resonance The concept of Helmholtz resonance

8611-483: 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, 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

8720-585: 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

8829-414: 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

8938-399: The neck is proportional to the length. The volume of the cavity appears in the denominator because the spring constant of the air in the cavity is inversely proportional to its volume. The area of the neck matters for two reasons. Increasing the area of the neck increases the inertia of the air proportionately, but also decreases the velocity at which the air rushes in and out. Depending on

9047-471: 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

9156-454: 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

9265-413: 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

9374-502: 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

9483-420: 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

9592-419: 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

9701-417: The response curve of the instrument consists of a series of Helmholtz resonance modes associated with the size and shape of the resonance cavity (harmonics of the fundamental cavity mode), as well as vibration damping from absorption by the resonance cavity material (typically wood). An ocarina is essentially a Helmholtz resonator where the combined area of the opened finger holes determines the note played by

9810-423: 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

10028-607: 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

10137-405: 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

10246-406: 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

10355-418: The spectral analysis of complex sounds. There is also an adjustable type, called a universal resonator, which consists of two cylinders , one inside the other, which can slide in or out to change the volume of the cavity over a continuous range. An array of 14 of this type of resonator has been employed in a mechanical Fourier sound analyzer . This resonator can also emit a variable-frequency tone when driven by

10464-476: 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

10573-542: 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,

10682-427: 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

10791-425: 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

10900-430: 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

11009-550: 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

11118-400: 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

11227-476: 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

11336-404: The use of bronze or pottery resonators in classical theater design. Helmholtz resonators are used in architectural acoustics to reduce undesirable low frequency sounds ( standing waves , etc.) by building a resonator tuned to the problem frequency, and putting absorbing material inside, thereby reducing it. In all stringed instruments, from the veena or sitar to the modern guitar and violin,

11445-453: 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

11554-453: 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

11663-492: The waves reflected by the resonator help cancel out certain frequencies of sound in the exhaust. In some two-stroke engines , a Helmholtz resonator is used to remove the need for a reed valve . A similar effect is also used in the exhaust system of most two-stroke engines, using a reflected pressure pulse to supercharge the cylinder (see Kadenacy effect ) . During the early 2010s, some Formula 1 teams used Helmholtz resonators in their cars' exhaust systems to help even out

11772-470: 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 the Spanish guitar in Italy. Even later, in the same century, Gaspar Sanz wrote that other nations such as Italy or France added to

11881-435: Was tuned by placing a finger on the second fret of the thinnest string and tuning the guitar bottom to top. The strings were a whole octave apart from one another, which is the reason for the different method of tuning. Because it was so different, there was major controversy as to who created the five course guitar. A literary source, Lope de Vega's Dorotea, gives the credit to the poet and musician Vicente Espinel . This claim
