Chronochromie (Time-Colour) is an orchestral work by French composer Olivier Messiaen , completed in 1960. It consists of seven movements:

#503496

110-619: The sixth movement consists of 18 string instruments playing different birdsong . The first performance was in Donaueschingen on 16 October 1960, conducted by Hans Rosbaud . The work is scored for the following orchestra: This article about a classical composition is a stub . You can help Misplaced Pages by expanding it . String instruments Plucked In musical instrument classification , string instruments , or chordophones , are musical instruments that produce sound from vibrating strings when

220-466: A monaural signal. Many guitars with active electronics use a jack with an extra contact normally used for stereo . These guitars use the extra contact to break the ground connection to the on-board battery to preserve battery life when the guitar is unplugged. These guitars require a mono plug to close the internal switch and connect the battery to ground. Standard guitar cables use a high-impedance 1 ⁄ 4 inch (6.35 mm) mono plug. These have

330-400: A vibrato embellishment. A plastic pickguard on some guitars protects the body from scratches or covers the control cavity, which holds most of the wiring. The degree to which the choice of woods and other materials in the solid-guitar body (3) affects the sonic character of the amplified signal is disputed. Many believe it is highly significant, while others think the difference between woods

440-413: A "normal" plucking point, producing a canonical harpsichord sound; the other has a plucking point close to the bridge, producing a reedier "nasal" sound rich in upper harmonics. A single string at a certain tension and length only produces one note. To produce multiple notes, string instruments use one of two methods. One is to add enough strings to cover the required range of different notes (e.g., as with

550-525: A United States patent for an Electrical Stringed Musical Instrument and the patent was later issued in 1937. By the time it was patented, other manufacturers were already making their own electric guitar designs. Early electric guitar manufacturers include Rickenbacker in 1932; Dobro in 1933; National, AudioVox and Volu-tone in 1934; Vega , Epiphone (Electrophone and Electar), and Gibson in 1935 and many others by 1936. By early-mid 1935, Electro String Instrument Corporation had achieved success with

660-590: A built-in system to electrically amplify their output without altering their tone as an alternative to using a separate microphone. The system may consist of piezoelectric pickups mounted under the bridge, or a low-mass microphone (usually a condenser mic) inside the body of the guitar that converts the vibrations in the body into electronic signals. Combinations of these types of pickups may be used, with an integral mixer/preamp/graphic equalizer. Such instruments are called electric acoustic guitars . They are regarded as acoustic guitars rather than electric guitars because

770-550: A cave painting in the Trois Frères cave in France depicts what some believe is a musical bow , a hunting bow used as a single-stringed musical instrument. From the musical bow, families of stringed instruments developed; since each string played a single note, adding strings added new notes, creating bow harps , harps and lyres . In turn, this led to being able to play dyads and chords . Another innovation occurred when

880-431: A challenge to instrument builders, as compared with instruments that are only plucked (e.g., guitar), because on bowed instruments, the musician must be able to play one string at a time if they wish. As such, a bowed instrument must have a curved bridge that makes the "outer" strings lower in height than the "inner" strings. With such a curved bridge, the player can select one string at a time to play. On guitars and lutes ,

990-411: A clock or bell. Electric string instruments, such as the electric guitar , can also be played without touching the strings by using audio feedback . When an electric guitar is plugged into a loud, powerful guitar amplifier with a loudspeaker and a high level of distortion is intentionally used, the guitar produces sustained high-pitched sounds. By changing the proximity of the guitar to the speaker,

1100-507: A fixed bridge or a spring-loaded hinged bridge , which lets players "bend" the pitch of notes or chords up or down, or perform vibrato effects. The sound of an electric guitar can be modified by new playing techniques such as string bending , tapping , and hammering-on , using audio feedback , or slide guitar playing. There are several types of electric guitar. Early forms were hollow-body semi-acoustic guitars , while solid body guitars developed later. String configurations include

1210-576: A folding neck called the "Foldaxe" was designed and built for Chet Atkins by Roger C. Field . Steinberger guitars developed a line of exotic, carbon fiber instruments without headstocks, with tuning done on the bridge instead. Fingerboards vary as much as necks. The fingerboard surface usually has a cross-sectional radius that is optimized to accommodate finger movement for different playing techniques. Fingerboard radius typically ranges from nearly flat (a very large radius) to radically arched (a small radius). The vintage Fender Telecaster , for example, has

1320-428: A guitar amplifier and speaker. When an electric guitar is played, string movement produces a signal by generating (i.e., inducing ) a small electric current in the magnetic pickups, which are magnets wound with coils of very fine wire. The signal passes through the tone and volume circuits to the output jack, and through a cable to an amplifier . The current induced is proportional to such factors as string density and

1430-517: A half a pear shape using three strings. Early versions of the violin and fiddle, by comparison, emerged in Europe through instruments such as the gittern , a four-stringed precursor to the guitar, and basic lutes . These instruments typically used catgut (animal intestine) and other materials, including silk, for their strings. String instrument design was refined during the Renaissance and into

1540-519: A hard, polymerized finish. Strings vibrating in the magnetic field of the pickups (3.1, 3.2) produce an electric current in the pickup winding that passes through the tone and volume controls (3.8) to the output jack. Some guitars have piezo pickups, in addition to or instead of magnetic pickups. Some guitars have a fixed bridge (3.4). Others have a spring-loaded hinged bridge called a vibrato bar , tremolo bar , or whammy bar , which lets players bend notes or chords up or down in pitch or perform

1650-498: A heavier metal winding produces a lower pitch than a string of equal length without a metal winding. This can be seen on a 2016-era set of gut strings for double bass. The higher-pitched G string is often made of synthetic material, or sometimes animal intestine, with no metal wrapping. To enable the low E string to produce a much lower pitch with a string of the same length, it is wrapped with many wrappings of thin metal wire. This adds to its mass without making it too stiff. The frequency

1760-484: A key part of orchestras – cellos, violas, and upright basses, for example, were now standard instruments for chamber ensembles and smaller orchestras. At the same time, the 19th-century guitar became more typically associated with six-string models, rather than traditional five-string versions. Major changes to string instruments in the 20th century primarily involved innovations in electronic instrument amplification and electronic music – electric violins were available by

1870-511: A key that plucks the string. Other musical instruments generate sound by striking the string. With bowed instruments, the player pulls a rosined horsehair bow across the strings, causing them to vibrate. With a hurdy-gurdy , the musician cranks a wheel whose rosined edge touches the strings. Bowed instruments include the string section instruments of the orchestra in Western classical music ( violin , viola , cello and double bass ) and

1980-540: A lute-like instrument came from Mesopotamia prior to 3000 BC. A cylinder seal from c.  3100 BC or earlier (now in the possession of the British Museum) shows what is thought to be a woman playing a stick lute. From the surviving images, theorists have categorized the Mesopotamian lutes, showing that they developed into a long variety and a short. The line of long lutes may have developed into

2090-658: A neck-through design is difficult or even impossible to repair, depending on the damage. Historically, the bolt-on style has been more popular for ease of installation and adjustment. Since bolt-on necks can be easily removed, there is an after-market in replacement bolt-on necks from companies such as Warmoth and Mighty Mite. Some instruments—notably most Gibson models—continue to use set-in glued necks. Neck-through bodies are somewhat more common in bass guitars. Materials for necks are selected for dimensional stability and rigidity, and some allege that they influence tone. Hardwoods are preferred, with maple , mahogany , and ash topping

2200-489: A number of other instruments (e.g., viols and gambas used in early music from the Baroque music era and fiddles used in many types of folk music ). All of the bowed string instruments can also be plucked with the fingers, a technique called " pizzicato ". A wide variety of techniques are used to sound notes on the electric guitar , including plucking with the fingernails or a plectrum, strumming and even " tapping " on

2310-401: A performance. The frequency is inversely proportional to the length: A string twice as long produces a tone of half the frequency (one octave lower). Pitch can be adjusted by varying the tension of the string. A string with less tension (looser) results in a lower pitch, while a string with greater tension (tighter) results in a higher pitch. Pushing a pedal on a pedal steel guitar raises

2420-401: A performer strums, plucks, strikes or sounds the strings in varying manners. Musicians play some string instruments, like guitars , by plucking the strings with their fingers or a plectrum (pick) , and others by hitting the strings with a light wooden hammer or by rubbing the strings with a bow , like violins . In some keyboard instruments, such as the harpsichord , the musician presses

2530-434: A rhythm guitarist and a lead guitarist. Many experiments with electrically amplifying the vibrations of a string instrument were made dating back to the early part of the 20th century. Patents from the 1910s show telephone transmitters were adapted and placed inside violins and banjos to amplify the sound. Hobbyists in the 1920s used carbon button microphones attached to the bridge ; however, these detected vibrations from

2640-423: A semi-acoustic tone (see below) or both. Semi-acoustic guitars have a hollow body similar to an acoustic guitar and electromagnetic pickups mounted directly into the body. They work in a similar way to solid-body electric guitars except that because the hollow body also vibrates, the pickups convert a combination of string and body vibration into an electrical signal. Many models, known as semi-hollow bodies, have

2750-418: A single block of wood, semi-acoustic guitar bodies are made from multiple pieces of wood in an archtop form, a method of construction different from the typical steel string acoustic guitar . The top is formed from a moderately thick piece of wood which is then carved into a thin outward-curving shape, whereas conventional acoustic guitars have a thin, flat top. Some steel-string acoustic guitars include

2860-570: A solid block running through the middle of the soundbox designed to reduce acoustic feedback. They do not provide enough acoustic volume for live performance, but they can be used unplugged for quiet practice. Semi-acoustic guitars are noted for being able to provide a sweet, plaintive, or funky tone. They are used in many genres, including jazz, blues, funk , sixties pop, and indie rock . They generally have cello-style F-shaped sound holes , which can be blocked off to further reduce feedback. Whereas chambered guitars are made, like solid-body guitars, from

2970-399: A tip and sleeve configuration referred to as a TS phone connector . The voltage is usually around 1 to 9 millivolts . A few guitars, such as Rickenbacker guitars equipped with Rick-O-Sound , feature stereo output. There are a variety of ways the "stereo" effect may be implemented. Commonly, but not exclusively, stereo guitars route the neck and bridge pickups to separate output buses on

3080-405: A top so heavily reinforced that it essentially functioned as a solid-body instrument. Unlike acoustic guitars, solid-body electric guitars have no vibrating soundboard to amplify string vibration. Instead, solid-body instruments depend on electric pickups, and an amplifier ("amp") and speaker . The solid body ensures that the amplified sound reproduces the string vibration alone, thus avoiding

3190-687: A triple single-coil guitar. The history of electric guitars has been summarized by Guitar World magazine, and the earliest electric guitar on their top 10 list is the Ro-Pat-In Electro A-25 "Frying Pan" (1932) described as "The first-fully functioning solid-body electric guitar to be manufactured and sold". It was the first electric guitar used in a publicly promoted performance, performed by Gage Brewer in Wichita, Kansas in October 1932. The most recent electric guitar on this list

3300-590: A typical small radius of approximately 7.25 inches (18.4 cm). Some manufacturers have experimented with fret profile and material, fret layout, number of frets, and modifications of the fingerboard surface for various reasons. Some innovations were intended to improve playability by ergonomic means, such as Warmoth Guitars' compound radius fingerboard. Scalloped fingerboards added enhanced microtonality during fast legato runs. Fanned frets intend to provide each string with an optimal playing tension and enhanced musicality. Some guitars have no frets , while others, like

3410-403: A violin scale is only about 13 inches (33 cm). On the shorter scale of the violin, the left hand may easily reach a range of slightly more than two octaves without shifting position , while on the bass' longer scale, a single octave or a ninth is reachable in lower positions. In bowed instruments, the bow is normally placed perpendicularly to the string, at a point halfway between the end of

3520-409: A way to reduce or counter the sound, as they are designed to "buck" (in the verb sense of oppose or resist ) the hum, hence their name. The high combined inductance of the two coils also leads to the richer, "fatter" tone associated with humbucking pickups. Electric guitar necks vary in composition and shape. The primary metric of guitar necks is the scale length , which is the vibrating length of

3630-409: A wood post with a neck attached and two hollow-body halves attached to the sides for appearance only — shares nothing in common for design or hardware with the solid-body Gibson Les Paul , designed by Ted McCarty and introduced in 1952. The feedback associated with amplified hollow-bodied electric guitars was understood long before Paul's "log" was created in 1940; Gage Brewer's Ro-Pat-In of 1932 had

3740-457: Is a guitar that requires external electric sound amplification in order to be heard at typical performance volumes, unlike a standard acoustic guitar . It uses one or more pickups to convert the vibration of its strings into electrical signals , which ultimately are reproduced as sound by loudspeakers . The sound is sometimes shaped or electronically altered to achieve different timbres or tonal qualities via amplifier settings or knobs on

3850-487: Is a method of playing on instruments such as the veena , banjo , ukulele , guitar, harp, lute , mandolin , oud , and sitar , using either a finger, thumb, or quills (now plastic plectra) to pluck the strings. Instruments normally played by bowing (see below) may also be plucked, a technique referred to by the Italian term pizzicato . Bowing (Italian: arco ) is a method used in some string instruments, including

3960-445: Is capable of a multitude of sounds and styles in genres ranging from pop and rock to folk to country music , blues and jazz . It served as a major component in the development of electric blues , rock and roll , rock music , heavy metal music and many other genres of music. Electric guitar design and construction varies greatly in the shape of the body and the configuration of the neck, bridge, and pickups. Guitars may have

4070-402: Is impractical. Instruments with a fingerboard are then played by adjusting the length of the vibrating portion of the strings. The following observations all apply to a string that is infinitely flexible (a theoretical assumption, because in practical applications, strings are not infinitely flexible) strung between two fixed supports. Real strings have finite curvature at the bridge and nut, and

4180-457: Is inversely proportional to the square root of the linear density: Given two strings of equal length and tension, the string with higher mass per unit length produces the lower pitch. The length of the string from nut to bridge on bowed or plucked instruments ultimately determines the distance between different notes on the instrument. For example, a double bass with its low range needs a scale length of around 42 inches (110 cm), whilst

4290-558: Is made of solid wood, without functionally resonating air spaces. The first solid-body Spanish standard guitar was offered by Vivi-Tone no later than 1934. This model featured a guitar-shaped body of a single sheet of plywood affixed to a wood frame. Another early, substantially solid Spanish electric guitar, called the Electro Spanish, was marketed by the Rickenbacker guitar company in 1935 and made of Bakelite . By 1936,

4400-409: Is mainly used on electric instruments because these have a pickup that amplifies only the local string vibration. It is possible on acoustic instruments as well, but less effective. For instance, a player might press on the seventh fret on a guitar and pluck it at the head side to make a tone resonate at the opposing side. On electric instruments, this technique generates multitone sounds reminiscent of

4510-406: Is often used in two roles: as a rhythm guitar , which plays the chord sequences or progressions , and riffs , and sets the beat (as part of a rhythm section ); and as a lead guitar , which provides instrumental melody lines, melodic instrumental fill passages, and solos . In a small group, such as a power trio , one guitarist may switch between both roles; in larger groups there is often

4620-523: Is one of the five main divisions of instruments in the Hornbostel–Sachs scheme of musical instrument classification . Hornbostel–Sachs divides chordophones into two main groups: instruments without a resonator as an integral part of the instrument (which have the classification number 31, also known as 'simple'); and instruments with such a resonator (which have the classification number 32, also known as 'composite'). Most western instruments fall into

4730-687: Is one of the oldest string instruments. Ancestors of the modern bowed string instruments are the rebab of the Islamic Empires, the Persian kamanche and the Byzantine lira . Other bowed instruments are the rebec , hardingfele , nyckelharpa , kokyū , erhu , igil , sarangi , morin khuur , and K'ni . The hurdy-gurdy is bowed by a wheel. Rarely, the guitar has been played with a bow (rather than plucked) for unique effects. The third common method of sound production in stringed instruments

4840-418: Is subtle. In acoustic and archtop guitars, wood choices more clearly affect tone. Woods typically used in solid-body electric guitars include alder (brighter, but well rounded), swamp ash (similar to alder, but with more pronounced highs and lows), mahogany (dark, bassy, warm), poplar (similar to alder), and basswood (very neutral). Maple , a very bright tonewood , is also a popular body wood but

4950-406: Is to strike the string. The piano and hammered dulcimer use this method of sound production. Even though the piano strikes the strings, the use of felt hammers means that the sound that is produced can nevertheless be mellow and rounded, in contrast to the sharp attack produced when a very hard hammer strikes the strings. Violin family string instrument players are occasionally instructed to strike

5060-450: Is very heavy. For this reason, it is often placed as a "cap" on a guitar made primarily of another wood. Cheaper guitars are often made of cheaper woods, such as plywood , pine , or agathis —not true hardwoods—which can affect durability and tone. Though most guitars are made of wood, any material may be used. Materials such as plastic, metal, and even cardboard have been used in some instruments. The guitar output jack typically provides

5170-506: The Baroque period (1600–1750) of musical history. Violins and guitars became more consistent in design and were roughly similar to acoustic guitars of the 2000s. The violins of the Renaissance featured intricate woodwork and stringing, while more elaborate bass instruments such as the bandora were produced alongside quill-plucked citterns , and Spanish body guitars. In the 19th century, string instruments were made more widely available through mass production, with wood string instruments

5280-754: The Gibson SG used by Angus Young from the group AC/DC . Some otherwise solid-bodied guitars, such as the Gibson Les Paul Supreme, the PRS Singlecut, and the Fender Telecaster Thinline , are built with hollow chambers in the body. These chambers are designed to not interfere with the critical bridge and string anchor point on the solid body. In the case of Gibson and PRS, these are called chambered bodies . The motivation for this may be to reduce weight, to achieve

5390-673: The Slingerland company introduced a wooden solid-body electric model, the Slingerland Songster 401 (and a lap steel counterpart, the Songster 400). Gibson's first production electric guitar, marketed in 1936, was the ES-150 model ("ES" for "Electric Spanish", and "150" reflecting the $ 150 price of the instrument, along with matching amplifier). The ES-150 guitar featured a single-coil, hexagonally shaped "bar" pickup, which

5500-455: The piano , which has sets of 88 strings to enable the performer to play 88 different notes). The other is to provide a way to stop the strings along their length to shorten the part that vibrates, which is the method used in guitar and violin family instruments to produce different notes from the same string. The piano and harp represent the first method, where each note on the instrument has its own string or course of multiple strings tuned to

5610-428: The saxophone and trumpet . The development of guitar amplifiers, which contained a power amplifier and a loudspeaker in a wooden cabinet , let jazz guitarists play solos and be heard over a big band. The development of the electric guitar provided guitarists with an instrument that was built to connect to guitar amplifiers. Electric guitars have magnetic pickups , volume control knobs and an output jack. In

5720-409: The six-string guitar (the most common type), which is usually tuned E, A, D, G, B, E, from lowest to highest strings; the seven-string guitar , which typically adds a low B string below the low E; the eight-string guitar , which typically adds a low E or F# string below the low B; and the twelve-string guitar , which has six two-string courses similar to a mandolin . In rock, the electric guitar

5830-469: The tamburs and pandura . The line of short lutes was further developed to the east of Mesopotamia, in Bactria , Gandhara , and Northwest India, and shown in sculpture from the 2nd century BC through the 4th or 5th centuries AD. During the medieval era , instrument development varied in different regions of the world. Middle Eastern rebecs represented breakthroughs in terms of shape and strings, with

5940-688: The violin , viola , cello , and the double bass (of the violin family ), and the old viol family. The bow consists of a stick with a "ribbon" of parallel horse tail hairs stretched between its ends. The hair is coated with rosin so it can grip the string; moving the hair across a string causes a stick-slip phenomenon , making the string vibrate , and prompting the instrument to emit sound. Darker grades of rosin grip well in cool, dry climates, but may be too sticky in warmer, more humid weather. Violin and viola players generally use harder, lighter-colored rosin than players of lower-pitched instruments, who tend to favor darker, softer rosin. The ravanahatha

6050-418: The wolf tones and unwanted feedback associated with amplified acoustic guitars. These guitars are generally made of hardwood covered with a hard polymer finish, often polyester or lacquer. In large production facilities, the wood is stored for three to six months in a wood-drying kiln before being cut to shape. Premium custom-built guitars are frequently made with much older , hand-selected wood. One of

6160-589: The "Frying Pan", and set out to capture a new audience through its release of the Electro-Spanish Model B and the Electro-Spanish Ken Roberts , which was the first full 25-inch scale electric guitar ever produced. The Electro-Spanish Ken Roberts was revolutionary for its time, providing players a full 25-inch scale, with easy access to 17 frets free of the body. Unlike other lap-steel electrified instruments produced during

6270-493: The 1920s and were an important part of emerging jazz music trends in the United States. The acoustic guitar was widely used in blues and jazz , but as an acoustic instrument, it was not loud enough to be a solo instrument, so these genres mostly used it as an accompaniment rhythm section instrument. In big bands of the 1920s, the acoustic guitar played backing chords, but it was not loud enough to play solos like

6380-465: The 1960s and 1970s, such as fuzz pedals , flangers , and phasers , enabling performers to create unique new sounds during the psychedelic rock era. Breakthroughs in electric guitar and bass technologies and playing styles enabled major breakthroughs in pop and rock music in the 1960s and 1970s. The distinctive sound of the amplified electric guitar was the centerpiece of new genres of music such as blues rock and jazz-rock fusion . The sonic power of

6490-408: The 1960s, larger, more powerful guitar amplifiers were developed, called "stacks". These powerful amplifiers enabled guitarists to perform in rock bands that played in large venues such as stadiums and outdoor music festivals (e.g., Woodstock Music Festival ). Along with the development of guitar amplifiers, a large range of electronic effects units , many in small stompbox pedals, were introduced in

6600-610: The Broadcaster. Another notable solid-body design is the Fender Stratocaster , which was introduced in 1954 and became extremely popular among musicians in the 1960s and 1970s for its wide tonal capabilities and more comfortable ergonomics than other models. Different styles of guitar have different pick-up styles, the main being 2 or 3 " single-coil " pick-ups or a double humbucker , with the Stratocaster being

6710-406: The action and strings of the piano were taken out of its box, it could still be played. This is not true of the violin , because the string passes over a bridge located on the resonator box, so removing the resonator would mean the strings had no tension. Curt Sachs also broke chordophones into four basic subcategories, "zithers, lutes, lyres and harps." Dating to around c.  13,000 BC ,

#1732780963504

6820-459: The air inside it. The vibration of the body of the instrument and the enclosed hollow or chamber make the vibration of the string more audible to the performer and audience. The body of most string instruments is hollow, in order to have better sound projection. Some, however—such as electric guitar and other instruments that rely on electronic amplification—may have a solid wood body. In musicology , string instruments are known as chordophones. It

6930-449: The amount of movement over the pickups. Because of their natural qualities, magnetic pickups tend to pick up ambient, usually unwanted electromagnetic interference or EMI. This mains hum results in a tone of 50 or 60 cycles per second depending on the powerline frequency of the local alternating current supply. The resulting hum is particularly strong with single-coil pickups. Double-coil or " humbucker " pickups were invented as

7040-633: The back of the guitar by metal ferrules . Many believe this design improves a guitar's sustain and timbre . A few examples of string-through body guitars are the Fender Telecaster Thinline , the Fender Telecaster Deluxe , the B.C. Rich IT Warlock and Mockingbird, and the Schecter Omen 6 and 7 series. Compared to an acoustic guitar, which has a hollow body, electric guitars make much less audible sound when their strings are plucked, so electric guitars are normally plugged into

7150-478: The bare fingers or a plectrum, bowed or (in the Aeolian harp, for instance) sounded by wind. The confusing plenitude of stringed instruments can be reduced to four fundamental type: zithers, lutes, lyres, and harps. In most string instruments, the vibrations are transmitted to the body of the instrument, which often incorporates some sort of hollow or enclosed area. The body of the instrument also vibrates, along with

7260-418: The body at the base of the guitar. These appear on Rickenbackers , Gretsches , Epiphones , a wide variety of archtop guitars , particularly jazz guitars , and the 1952 Gibson Les Paul. Pictured is a tremolo arm or vibrato tailpiece - style bridge and tailpiece system, often called a whammy bar or trem . It uses a lever ("vibrato arm") attached to the bridge that can temporarily slacken or tighten

7370-430: The body. Set-in necks are glued to the body at the factory. This is the traditional type of joint. Leo Fender pioneered bolt-on necks on electric guitars to facilitate easy adjustment and replacement. Neck-through instruments extend the neck to the length of the instrument so that it forms the center of the body. While a set-in neck can be carefully unglued by a skilled luthier , and a bolt-on neck can simply be unscrewed,

7480-437: The bow harp was straightened out and a bridge used to lift the strings off the stick-neck , creating the lute. This picture of musical bow to harp bow is theory and has been contested. In 1965 Franz Jahnel wrote his criticism stating that the early ancestors of plucked instruments are not currently known. He felt that the harp bow was a long cry from the sophistication of the civilizations of western Asia in 4000 BC that took

7590-487: The bridge can be flat, because the strings are played by plucking them with the fingers, fingernails or a pick; by moving the fingers or pick to different positions, the player can play different strings. On bowed instruments, the need to play strings individually with the bow also limits the number of strings to about six or seven; with more strings, it would be impossible to select individual strings to bow. (Bowed strings can also play two bowed notes on two different strings at

7700-555: The bridge on top of the instrument, resulting in a weak signal. Electric guitars were originally designed by acoustic guitar makers and instrument manufacturers. The demand for amplified guitars began during the big band era; as orchestras increased in size, guitar players soon realized the necessity in guitar amplification and electrification. The first electric guitars used in jazz were hollow archtop acoustic guitar bodies with electromagnetic transducers . The first electrically amplified stringed instrument to be marketed commercially

7810-421: The bridge, because of its motion, is not exactly nodes of vibration. Hence the following statements about proportionality are approximations. Pitch can be adjusted by varying the length of the string. A longer string results in a lower pitch, while a shorter string results in a higher pitch. A concert harp has pedals that cause a hard object to make contact with a string to shorten its vibrating length during

7920-546: The closer the fret spacing. Opinions vary regarding the effect of scale length on tone and feel. Popular opinion holds that longer scale length contributes to greater amplitude . Reports of playing feel are greatly complicated by the many factors involved in this perception. String gauge and design, neck construction and relief, guitar setup, playing style, and other factors contribute to the subjective impression of playability or feel. Necks are described as bolt-on , set-in , or neck-through , depending on how they attach to

8030-441: The difference is perhaps more subtle. In keyboard instruments, the contact point along the string (whether this be hammer, tangent, or plectrum) is a choice made by the instrument designer. Builders use a combination of experience and acoustic theory to establish the right set of contact points. In harpsichords, often there are two sets of strings of equal length. These "choirs" usually differ in their plucking points. One choir has

8140-399: The different parts of an electric guitar. The headstock (1) contains the metal machine heads (1.1), which use a worm gear for tuning. The nut (1.4)—a thin fret-like strip of metal, plastic, graphite, or bone—supports the strings at the headstock end of the instrument. The frets (2.3) are thin metal strips that stop the string at the correct pitch when the player pushes a string against

8250-468: The dynamic and timbre (tone colour) range of orchestras, bands, and solo performances. String instruments can be divided into three groups: It is also possible to divide the instruments into categories focused on how the instrument is played. All string instruments produce sound from one or more vibrating strings , transferred to the air by the body of the instrument (or by a pickup in electronically amplified instruments). They are usually categorised by

8360-538: The effects of different woods or materials on the electric guitar sound. Several neck shapes appear on guitars, including shapes known as C necks, U necks, and V necks. These refer to the cross-sectional shape of the neck (especially near the nut). Several sizes of fret wire are available, with traditional players often preferring thin frets, and metal shredders liking thick frets. Thin frets are considered better for playing chords, while thick frets allow lead guitarists to bend notes with less effort. An electric guitar with

8470-467: The electric guitar was adopted by jazz guitar players, who wanted to play single-note guitar solos in large big band ensembles. Early proponents of the electric guitar on record include Les Paul , Eddie Durham , George Barnes , Lonnie Johnson , Sister Rosetta Tharpe , T-Bone Walker , and Charlie Christian . During the 1950s and 1960s, the electric guitar became the most important instrument in popular music . It has evolved into an instrument that

8580-498: The fingerboard and the bridge. However, different bow placements can be selected to change timbre . Application of the bow close to the bridge (known as sul ponticello ) produces an intense, sometimes harsh sound, which acoustically emphasizes the upper harmonics . Bowing above the fingerboard ( sul tasto ) produces a purer tone with less overtone strength, emphasizing the fundamental , also known as flautando , since it sounds less reedy and more flute-like. Bowed instruments pose

8690-554: The fingerboard and using feedback from a loud, distorted guitar amplifier to produce a sustained sound. Some string instruments are mainly plucked, such as the harp and the electric bass . Other examples include the sitar , rebab , banjo , mandolin , ukulele , and bouzouki . In the Hornbostel–Sachs scheme of musical instrument classification , used in organology , string instruments are called chordophones. According to Sachs , Chordophones are instruments with strings. The strings may be struck with sticks, plucked with

8800-420: The fingerboard. The truss rod (1.2) is a metal rod (usually adjustable) that counters the tension of the strings to keep the neck straight. Position markers (2.2) provide the player with a reference to the playing position on the fingerboard. The neck and fretboard (2.1) extend from the body. At the neck joint (2.4), the neck is either glued or bolted to the body. The body (3) is typically made of wood with

8910-432: The first improvements on the vibrato system in many years when, in the late 1970s, he experimented with "locking" nuts and bridges that prevent the guitar from losing tuning, even under heavy vibrato bar use. The fourth type of system employs string-through body anchoring. The strings pass over the bridge saddles, then through holes through the top of the guitar body to the back. The strings are typically anchored in place at

9020-432: The first solid-body guitars was invented by Les Paul . Gibson did not present their Gibson Les Paul guitar prototypes to the public, as they did not believe the solid-body style would catch on. Another early solid-body Spanish style guitar, resembling what would become Gibson's Les Paul guitar a decade later, was developed in 1941 by O.W. Appleton, of Nogales, Arizona. Appleton made contact with both Gibson and Fender but

9130-401: The guitar, bass, violin, etc.) can be played using a magnetic field. An E-Bow is a small hand-held battery-powered device that magnetically excites the strings of an electric string instrument to provide a sustained, singing tone reminiscent of a held bowed violin note. Third bridge is a plucking method where the player frets a string and strikes the side opposite the bridge. The technique

9240-926: The guitar. A stereo cable then routes each pickup to its signal chain or amplifier. For these applications, the most popular connector is a high-impedance 1 ⁄ 4 inch (6.35 mm) plug with a tip, ring, and sleeve configuration, also known as a TRS phone connector . Some studio instruments, notably certain Gibson Les Paul models, incorporate a low- impedance three-pin XLR connector for balanced audio . Many exotic arrangements and connectors exist that support features such as midi and hexaphonic pickups. The bridge and tailpiece , while serving separate purposes, work closely together to affect playing style and tone. There are four basic types of bridge and tailpiece systems on electric guitars. Within these four types are many variants. A hard-tail guitar bridge anchors

9350-404: The guitar. Often, this is done through the use of effects such as reverb , distortion and "overdrive" ; the latter is considered to be a key element of electric blues guitar music and jazz , rock and heavy metal guitar playing. Designs also exist combining attributes of electric and acoustic guitars: the semi-acoustic and acoustic-electric guitars. Invented in 1932 by Johannes Isaac,

9460-419: The guitarist can produce sounds that cannot be produced with standard plucking and picking techniques. This technique was popularized by Jimi Hendrix and others in the 1960s. It was widely used in psychedelic rock and heavy metal music . There are three ways to change the pitch of a vibrating string . String instruments are tuned by varying a string's tension because adjusting length or mass per unit length

9570-649: The list. The neck and fingerboard can be made from different materials; for example, a guitar may have a maple neck with a rosewood or ebony fingerboard. Today there are expensive and budget guitars exploring other options for fretboard wood for instance Pau-Ferro , both for availability and cheap price while still maintaining quality. In the 1970s, designers began to use exotic human-made materials such as aircraft-grade aluminum , carbon fiber , and ebonol . Makers known for these unusual materials include John Veleno , Travis Bean , Geoff Gould , and Alembic . Aside from possible engineering advantages, some feel that with

9680-478: The loudly amplified, highly distorted electric guitar was the key element of the early heavy metal music , with the distorted guitar being used in lead guitar roles, and with power chords as a rhythm guitar . The ongoing use of electronic amplification and effects units in string instruments, ranging from traditional instruments like the violin to the new electric guitar, added variety to contemporary classical music performances, and enabled experimentation in

9790-423: The pickups do not produce a signal directly from the vibration of the strings, but rather from the vibration of the guitar top or body, and the amplification of the sound merely increases volume, not alters tone. Electric guitar design and construction vary greatly in the shape of the body and the configuration of the neck, bridge, and pickups. However, some features are present on most guitars. The photo below shows

9900-402: The pitch of certain strings by increasing tension on them (stretching) through a mechanical linkage; release of the pedal returns the pitch to the original. Knee levers on the instrument can lower a pitch by releasing (and restoring) tension in the same way. A homemade washtub bass made out of a length of rope, a broomstick and a washtub can produce different pitches by increasing the tension on

10010-451: The player presses keys on to trigger a mechanism that sounds the strings, instead of directly manipulating the strings. These include the piano , the clavichord , and the harpsichord. With these keyboard instruments , strings are occasionally plucked or bowed by hand. Modern composers such as Henry Cowell wrote music that requires that the player reach inside the piano and pluck the strings directly, "bow" them with bow hair wrapped around

10120-491: The primitive technology and created "technically and artistically well-made harps, lyres, citharas, and lutes." Archaeological digs have identified some of the earliest stringed instruments in Ancient Mesopotamian sites, like the lyres of Ur , which include artifacts over three thousand years old. The development of lyre instruments required the technology to create a tuning mechanism to tighten and loosen

10230-592: The rising cost of rare tonewoods , human-made materials may be economically preferable and more ecologically sensitive. However, wood remains popular in production instruments, though sometimes in conjunction with new materials. Vigier guitars , for example, use a wooden neck reinforced by embedding a light, carbon fiber rod in place of the usual heavier steel bar or adjustable steel truss rod. After-market necks made entirely from carbon fiber fit existing bolt-on instruments. Few, if any, extensive formal investigations have been widely published that confirm or refute claims over

10340-427: The rope (producing a higher pitch) or reducing the tension (producing a lower pitch). The frequency is proportional to the square root of the tension: The pitch of a string can also be varied by changing the linear density (mass per unit length) of the string. In practical applications, such as with double bass strings or bass piano strings, extra weight is added to strings by winding them with metal. A string with

10450-456: The same note. (Many notes on a piano are strung with a "choir" of three strings tuned alike, to increase the volume.) A guitar represents the second method—the player's fingers push the string against the fingerboard so that the string is pressed firmly against a metal fret. Pressing the string against a fret while plucking or strumming it shortens the vibrating part and thus produces a different note. Electric guitar An electric guitar

10560-531: The same time, a technique called a double stop .) Indeed, on the orchestral string section instruments, four strings are the norm, with the exception of five strings used on some double basses . In contrast, with stringed keyboard instruments, 88 courses are used on a piano , and even though these strings are arranged on a flat bridge, the mechanism can play any of the notes individually. Similar timbral distinctions are also possible with plucked string instruments by selecting an appropriate plucking point, although

10670-399: The second group, but the piano and harpsichord fall into the first. Hornbostel and Sachs' criterion for determining which sub-group an instrument falls into is that if the resonator can be removed without destroying the instrument, then it is classified as 31. The idea that the piano's casing, which acts as a resonator, could be removed without destroying the instrument, may seem odd, but if

10780-533: The string tension. Lyres with wooden bodies and strings used for plucking or playing with a bow represent key instruments that point towards later harps and violin-type instruments; moreover, Indian instruments from 500 BC have been discovered with anything from 7 to 21 strings. In Vietnam, a 2,000 year old, singularly stringed instrument made of deer antler was also discovered. Musicologists have put forth examples of that 4th-century BC technology, looking at engraved images that have survived. The earliest image showing

10890-449: The string with the stick of the bow, a technique called col legno . This yields a percussive sound along with the pitch of the note. A well-known use of col legno for orchestral strings is Gustav Holst 's "Mars" movement from The Planets suite. The aeolian harp employs a very unusual method of sound production: the strings are excited by the movement of the air. Some instruments that have strings have an attached keyboard that

11000-538: The strings at or directly behind the bridge and is fastened securely to the top of the instrument. These are common on carved-top guitars, such as the Gibson Les Paul and the Paul Reed Smith models , and on slab-body guitars, such as the Music Man Albert Lee and Fender guitars that are not equipped with a vibrato arm. A floating or trapeze tailpiece (similar to a violin 's) fastens to

11110-461: The strings from nut to bridge. A typical Fender guitar uses a 25.5-inch (65 cm) scale length, while Gibson uses a 24.75-inch (62.9 cm) scale length in their Les Paul . While the scale length of the Les Paul is often described as 24.75 inches, it has varied through the years by as much as a half inch. Frets are positioned proportionally to scale length—the shorter the scale length,

11220-668: The strings to alter the pitch . A player can use this to create a vibrato or a portamento effect. Early vibrato systems were often unreliable and made the guitar go out of tune easily. They also had a limited pitch range. Later Fender designs were better, but Fender held the patent on these, so other companies used older designs for many years. With the expiration of the Fender patent on the Stratocaster -style vibrato, various improvements on this type of internal, multi-spring vibrato system are now available. Floyd Rose introduced one of

11330-419: The strings, or play them by rolling the bell of a brass instrument such as a trombone on the array of strings. However, these are relatively rarely used special techniques. Other keyed string instruments, small enough for a strolling musician to play, include the plucked autoharp , the bowed nyckelharpa , and the hurdy-gurdy, which is played by cranking a rosined wheel. Steel-stringed instruments (such as

11440-404: The technique used to make the strings vibrate (or by the primary technique, in the case of instruments where more than one may apply). The three most common techniques are plucking, bowing, and striking. An important difference between bowing and plucking is that in the former the phenomenon is periodic so that the overtones are kept in a strictly harmonic relationship to the fundamental. Plucking

11550-592: The time, the Electro-Spanish Ken Roberts was designed to play while standing upright with the guitar on a strap, as with acoustic guitars. The Electro-Spanish Ken Roberts was also the first instrument to feature a hand-operated vibrato as a standard arrangement, a device called the "Vibrola", invented by Doc Kauffman . It is estimated that fewer than 50 Electro-Spanish Ken Roberts were constructed between 1933 and 1937; fewer than 10 are known to survive today. The solid-body electric guitar

11660-693: The vibrations of the guitar strings into electrical signals, which could then be amplified. Commercial production began in late summer of 1932 by the Ro-Pat-In Corporation (Elect ro - Pat ent- In strument Company), in Los Angeles, a partnership of Beauchamp, Adolph Rickenbacker (originally Rickenbacher), and Paul Barth. In 1934, the company was renamed the Rickenbacker Electro Stringed Instrument Company. In that year Beauchamp applied for

11770-505: Was a cast aluminium lap steel guitar nicknamed the "Frying Pan" designed in 1931 by George Beauchamp , the general manager of the National Stringed Instrument Corporation , with Paul Barth, who was vice president. George Beauchamp, along with Adolph Rickenbacker , invented the electromagnetic pickups. Coils that were wrapped around a magnet would create an electromagnetic field that converted

11880-479: Was designed by Walt Fuller. It became known as the " Charlie Christian " pickup (named for the jazz guitarist who was among the first to perform with the ES-150 guitar). The ES-150 achieved some popularity but suffered from unequal loudness across the six strings. A functioning solid-body electric guitar was designed and built in 1940 by Les Paul from an Epiphone acoustic archtop as an experiment. His " log guitar " —

11990-743: Was the Ibanez Jem (1987) which featured "24 frets", an impossibly thin neck" and was "designed to be the ultimate shredder machine". Numerous other important electric guitars are on the list, including Gibson ES-150 (1936), Fender Telecaster (1951), Gibson Les Paul (1952), Gretsch 6128 Duo Jet (1953), Fender Stratocaster (1954), Rickenbacker 360/12 (1964), Van Halen Frankenstrat (1975), Paul Reed Smith Custom (1985) many of these guitars were "successors" to earlier designs. Electric guitar designs eventually became culturally important and visually iconic, with various model companies selling miniature model versions of particularly famous electric guitars, for example,

12100-553: Was unable to sell the idea behind his "App" guitar to either company. In 1946, Merle Travis commissioned steel guitar builder Paul Bigsby to build him a solid-body Spanish-style electric. Bigsby delivered the guitar in 1948. The first mass-produced solid-body guitar was Fender Esquire and Fender Broadcaster (later to become the Fender Telecaster ), first made in 1950, five years after Les Paul made his prototype . The Gibson Les Paul appeared soon after to compete with
