The guitar is a stringed musical instrument that is usually fretted and typically has six or twelve strings. It is usually held flat against the player's body and played by strumming or plucking the strings with the dominant hand, while simultaneously pressing selected strings against frets with the fingers of the opposite hand. A guitar pick may also be used to strike 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.
In music, there are two common meanings for tuning:
A power chord, also called a fifth chord, is a colloquial name for a chord on guitar, especially on electric guitar, that consists of the root note and the fifth, as well as possibly octaves of those notes. Power chords are commonly played with an amp with intentionally added distortion or overdrive effects. Power chords are a key element of many styles of rock, especially heavy metal and punk rock.
The bouzouki is a musical instrument popular in Greece. It is a member of the long-necked lute family, with a round body with a flat top and a long neck with a fretted fingerboard. It has steel strings and is played with a plectrum producing a sharp metallic sound, reminiscent of a mandolin but pitched lower. It is the precursor to the Irish bouzouki, an instrument derived from the Greek bouzouki that is popular in Celtic, English, and North American folk music. There are two main types of Greek bouzouki: the trichordo (three-course) has three pairs of strings and the tetrachordo (four-course) has four pairs of strings. The instrument was brought to Greece in the early 1900s by Greek refugees from Anatolia, and quickly became the central instrument to the rebetiko genre and its music branches. It is now an important element of modern Laïko pop Greek music.
Scordatura is a tuning of a string instrument that is different from the normal, standard tuning. It typically attempts to allow special effects or unusual chords or timbre, or to make certain passages easier to play. It is common to notate the finger position as if played in regular tuning, while the actual pitch resulting is altered. When all the strings are tuned by the same interval up or down, as in the case of the viola in Mozart's Sinfonia Concertante for Violin, Viola and Orchestra, the part is transposed as a whole.
The Appalachian dulcimer is a fretted string instrument of the zither family, typically with three or four strings, originally played in the Appalachian region of the United States. The body extends the length of the fingerboard, and its fretting is generally diatonic.
The seven-string guitar adds one additional string to the more common six-string guitar, commonly used to extend the bass range or also to extend the treble range.
An eight-string guitar is a guitar with eight strings, or one more than the Russian guitar's seven. Eight-string guitars are less common than six- and seven-string guitars, but they are used by a few classical, jazz, and metal guitarists. The eight-string guitar allows a wider tonal range, or non-standard tunings, or both.
In music, a guitar chord is a set of notes played on a guitar. A chord's notes are often played simultaneously, but they can be played sequentially in an arpeggio. The implementation of guitar chords depends on the guitar tuning. Most guitars used in popular music have six strings with the "standard" tuning of the Spanish classical guitar, namely E–A–D–G–B–E' ; in standard tuning, the intervals present among adjacent strings are perfect fourths except for the major third (G,B). Standard tuning requires four chord-shapes for the major triads.
Guitar tunings are the assignment of pitches to the open strings of guitars, including classical guitars, acoustic guitars, and electric guitars. Tunings are described by the particular pitches that are made by notes in Western music. By convention, the notes are ordered and arranged from the lowest-pitched string to the highest-pitched string, or the thickest string to thinnest, or the lowest frequency to the highest. This sometimes confuses beginner guitarists, since the highest-pitched string is referred to as the 1st string, and the lowest-pitched is the 6th string.
Open D tuning is an open tuning for the acoustic or electric guitar. The open string notes in this tuning are : D A D F♯ A D. It uses the three notes that form the triad of a D major chord: D, F♯ and A.
An extended-range bass is an electric bass guitar with a wider frequency range than a standard-tuned four-string bass guitar.
The octave mandolin or octave mandola is a fretted string instrument with four pairs of strings tuned in fifths, G−D−A−E. 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.
Open C tuning is an open tuning for guitar. The open-string notes form a C major chord, which is the triad (C,E,G) having the root note C, the major third (C,E), and the perfect fifth (C,G). When the guitar is strummed without fretting any strings, a C-major chord is sounded. By barring all of the strings for one fret, one finger suffices to fret the other eleven major-chords.
Each bass guitar tuning assigns pitches to the strings of an electric bass. Because pitches are associated with notes, bass-guitar tunings assign open notes to open strings. There are several techniques for accurately tuning the strings of an electric bass. Bass method or lesson books introduce one or more tuning techniques, such as:
This is a glossary of jazz and popular music terms that are likely to be encountered in printed popular music songbooks, fake books and vocal scores, big band scores, jazz, and rock concert reviews, and album liner notes. This glossary includes terms for musical instruments, playing or singing techniques, amplifiers, effects units, sound reinforcement equipment, and recording gear and techniques which are widely used in jazz and popular music. Most of the terms are in English, but in some cases, terms from other languages are encountered.
Among alternative tunings for guitar, a major-thirds tuning is a regular tuning in which each interval between successive open strings is a major third. Other names for major-thirds tuning include major-third tuning, M3 tuning, all-thirds tuning, and augmented tuning. By definition, a major-third interval separates two notes that differ by exactly four semitones.
Among alternative guitar-tunings, regular tunings have equal musical intervals between the paired notes of their successive open strings.
Among alternative tunings for the guitar, an overtones tuning selects its open-string notes from the overtone sequence of a fundamental note. An example is the open tuning constituted by the first six overtones of the fundamental note C, namely C2-C3-G3-C4-E4-G4.
