The steel-string acoustic guitar is a modern form of guitar that descends from the gut-strung Romantic guitar, but is strung with steel strings for a brighter, louder sound. Like the modern classical guitar, it is often referred to simply as an acoustic guitar, or sometimes as a folk guitar.
An electric guitar is a guitar that requires external 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 from that of an acoustic guitar via amplifier settings or knobs on 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 and rock guitar playing. Designs also exist combining attributes of the electric and acoustic guitars: the semi-acoustic and acoustic-electric guitars.
The guitar is a fretted musical instrument that typically has six strings. It is usually held flat against the player's body and played by strumming or plucking the strings with the dominant hand, while simultaneously pressing selected strings against frets with the fingers of the opposite hand. A plectrum or individual finger picks may also be used to strike the strings. The sound of the guitar is projected either acoustically, by means of a resonant chamber on the instrument, or amplified by an electronic pickup and an amplifier.
A mandolin is a stringed musical instrument in the lute family and is generally plucked with a pick. It most commonly has four courses of doubled strings tuned in unison, thus giving a total of eight strings. A variety of string types are used, with steel strings being the most common and usually the least expensive. The courses are typically tuned in an interval of perfect fifths, with the same tuning as a violin. Also, like the violin, it is the soprano member of a family that includes the mandola, octave mandolin, mandocello and mandobass.
A sound board, or soundboard, is the surface of a string instrument that the strings vibrate against, usually via some sort of bridge. Pianos, guitars, banjos, and many other stringed instruments incorporate soundboards. The resonant properties of the sound board and the interior of the instrument greatly increase the loudness of the vibrating strings. "The soundboard is probably the most important element of a guitar in terms of its influence on the quality of the instrument's tone [timbre]."
When the [guitar] top vibrates, it generates sound waves, much like a loudspeaker. As the soundboard moves forward, the air that is in front of it is compressed and it moves away from the guitar. As the soundboard moves back, the pressure on the air in front of the guitar is reduced. This is called a "rarefaction," and air rushes in to fill the rarefied region. Through this process, an alternating series of compression and rarefaction pulses travel away from the soundboard, creating sound waves.
A luthier is a craftsperson who builds or repairs string instruments that have a neck and a sound box. The word luthier is originally French and comes from the French word for lute. The term was originally used for makers of lutes, but it came to be used in French for makers of most bowed and plucked stringed instruments such as members of the violin family and guitars. Luthiers, however, do not make harps or pianos; these require different skills and construction methods because their strings are secured to a frame.
A semi-acoustic guitar, also known as a hollow-body electric guitar, is a type of electric guitar designed to be played with a guitar amplifier featuring a fully or partly hollow body and at least one electromagnetic pickup. First created in the 1930s, they became popular in jazz and blues, where they remain widely used, and the early period of rock & roll, though they were later largely supplanted by solid-body electric guitars in rock.
An archtop guitar is a hollow acoustic or semi-acoustic guitar with a full body and a distinctive arched top, whose sound is particularly popular with jazz, blues, and rockabilly players.
The Selmer guitar — often called a Selmer-Maccaferri or just Maccaferri by English speakers, as early British advertising stressed the designer rather than manufacturer — is an unusual acoustic guitar best known as the favored instrument of Django Reinhardt. Selmer, a French manufacturer, produced the instrument from 1932 to about 1952.
The Ovation Guitar Company is a manufacturer of string instruments. Ovation primarily manufactures steel-string acoustic guitars and nylon-string guitars, often with pickups for electric amplification. In 2015, it became a subsidiary of Drum Workshop after being acquired from KMCMusicorp.
Lloyd Allayre Loar (1886–1943) was an American musician, instrument designer and sound engineer. He is best known for his design work with the Gibson Mandolin-Guitar Mfg. Co. Ltd. in the early 20th century, including the F-5 model mandolin and L-5 guitar. In his later years he worked on electric amplification of stringed instruments, and demonstrated them around the country. One example, played in public in 1938 was an electric viola that used electric coils beneath the bridge, with no back, able to "drown out the loudest trumpet."
The tenor guitar or four-string guitar is a slightly smaller, four-string relative of the steel-string acoustic guitar or electric guitar. The instrument was initially developed in its acoustic form by Gibson and C.F. Martin so that players of the four-string tenor banjo could double on guitar.
Inlay on guitars or similar fretted instruments are decorative materials set into the wooden surface of the instrument using standard inlay techniques. Although inlay can be done on any part of a guitar, it is most commonly found on the fretboard, headstock—typically the manufacturer's logo—and around the sound hole of acoustic guitars. Only the positional markers on the fretboard or side of the neck and the rosette around the sound hole serve any function other than decoration. Nacre, plastic and wood are the materials most often used as inlay.
The octave mandolin or octave mandola is a fretted string instrument with four pairs of strings tuned in fifths, G−D−A−E, an octave below a mandolin. It is larger than the mandola, but smaller than the mandocello and its construction is similar to other instruments in the mandolin family. Usually the courses are all unison pairs but the lower two may sometimes be strung as octave pairs with the higher-pitched octave string on top so that it is hit before the thicker lower-pitched string. Alternate tunings of G−D−A−D and A−D−A−D are often employed by Celtic musicians.
An acoustic guitar is a musical instrument in the string family. When a string is plucked, its vibration is transmitted from the bridge, resonating throughout the top of the guitar. It is also transmitted to the side and back of the instrument, resonating through the air in the body, and producing sound from the sound hole. The original, general term for this stringed instrument is guitar, and the retronym 'acoustic guitar' distinguishes it from an electric guitar, which relies on electronic amplification. Typically, a guitar's body is a sound box, of which the top side serves as a sound board that enhances the vibration sounds of the strings. In standard tuning the guitar's six strings are tuned (low to high) E2 A2 D3 G3 B3 E4.
Tacoma Guitars was an American manufacturing company of musical instruments. It was founded in 1991 as a division of South Korean company Young Chang. Instruments were manufactured in Tacoma, Washington. The company and brand name were later acquired by the Fender Musical Instruments Corporation. The Tacoma plant closed, and production ceased, in 2008.
The Gibson ES series of semi-acoustic guitars are manufactured by the Gibson Guitar Corporation.
A bridge is a device that supports the strings on a stringed musical instrument and transmits the vibration of those strings to another structural component of the instrument—typically a soundboard, such as the top of a guitar or violin—which transfers the sound to the surrounding air. Depending on the instrument, the bridge may be made of carved wood, metal or other materials. The bridge supports the strings and holds them over the body of the instrument under tension.
Guitar bracing refers to the system of wooden struts which internally support and reinforce the soundboard and back of acoustic guitars.
Grimshaw Guitars was a British manufacturer of guitars and related instruments from the 1930s to the 1980s, known for producing acoustic archtop guitars in the 1930s–1940s, electrified archtop guitars in the 1940s and 1950s, semi-solid (thinline) electric guitars in the 1950s–1960s, and mainly solidbody guitars from the late 1950s to 1980s, along with smaller quantities of banjos, hawaiian guitars, electric bass guitars, acoustic guitars and nylon string guitars. Their archtop guitars were used by British players from the 1930s to the 1950s, when equivalent U.S.-made instruments were difficult to obtain in Britain, and their early electric thinline instruments such as the "S.S.1" and "S.S.1 deluxe" were popular with British "beat" groups of the early 1960s. Sales declined in the later 1960s and 1970s with easier access by customers to better made U.S. instruments at one end of the scale, and cheaper imported instruments, mostly from Japan, with which the Grimshaw line could not compete on price. The Grimshaw factory closed in the mid 1980s and its junior partner founder, Emile Grimshaw Jnr, passed away in 1987. Since that time, surviving instruments occasionally appear on the used market but tend to be somewhat overshadowed in favour of better known instruments of similar age by other British manufacturers such as Burns, Vox, etc.
