The banjo is a stringed instrument with a thin membrane stretched over a frame or cavity to form a resonator. The membrane is typically circular, in modern forms usually made of plastic, originally of animal skin. Early forms of the instrument were fashioned by African Americans and had African antecedents. In the 19th century, interest in the instrument was spread across the United States and United Kingdom by traveling shows of the 19th century minstrel show fad, followed by mass-production and mail-order sales, including instruction method books. The inexpensive or home-made banjo remained part of rural folk culture, but 5-string and 4-string banjos also became popular for home parlor music entertainment, college music clubs, and early 20th century jazz bands. By the early 21st century, the banjo was most frequently associated with folk, bluegrass and country music, but was also used in some rock, pop and even hip-hop music. Among rock bands, the Eagles, Led Zeppelin, and the Grateful Dead have used the five-string banjo in some of their songs. Some famous pickers of the banjo are Ralph Stanley and Earl Scruggs.
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.
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.
In music, there are two common meanings for tuning:
The ukulele, also called a uke, is a member of the lute family of instruments of Portuguese origin and popularized in Hawaii. It generally employs four nylon strings.
A capo is a device a musician uses on the neck of a stringed instrument to transpose and shorten the playable length of the strings—hence raising the pitch. It is a common tool for players of guitars, mandolins, mandolas, banjos, ukuleles and bouzoukis. The word derives from the Italian capotasto, which means the nut of a stringed instrument. The earliest known use of capotasto is by Giovanni Battista Doni who, in his Annotazioni of 1640, uses it to describe the nut of a viola da gamba. The first patented capo was designed by James Ashborn of Wolcottville, Connecticut year 1850.
A twelve-string guitar is a steel-string guitar with 12 strings in six courses, which produces a thicker, more ringing tone than a standard six-string guitar. Typically, the strings of the lower four courses are tuned in octaves, with those of the upper two courses tuned in unison. The gap between the strings within each dual-string course is narrow, and the strings of each course are fretted and plucked as a single unit. The neck is wider, to accommodate the extra strings, and is similar to the width of a classical guitar neck. The sound, particularly on acoustic instruments, is fuller and more harmonically resonant than six-string instruments. The 12-string guitar can be played like a 6-string guitar as players still use the same notes, chords and guitar techniques like a standard 6-string guitar, but advanced techniques might be tough as players need to play or pluck two strings simultaneously.
The fingerboard is an important component of most stringed instruments. It is a thin, long strip of material, usually wood, that is laminated to the front of the neck of an instrument. The strings run over the fingerboard, between the nut and bridge. To play the instrument, a musician presses strings down to the fingerboard to change the vibrating length, changing the pitch. This is called stopping the strings. Depending on the instrument and the style of music, the musician may pluck, strum or bow one or more strings with the hand that is not fretting the notes. On some instruments, notes can be sounded by the fretting hand alone, such as with hammer ons, an electric guitar technique.
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.
The cümbüş is a Turkish stringed instrument of relatively modern origin. It was developed in 1930 by Zeynel Abidin Cümbüş as an oud-like instrument that could be heard as part of a larger ensemble.
The baritone guitar is a guitar with a longer scale length, typically a larger body, and heavier internal bracing, so it can be tuned to a lower pitch. Gretsch, Fender, Gibson, Ibanez, ESP Guitars, PRS Guitars, Music Man, Danelectro, Schecter, Jerry Jones Guitars, Burns London and many other companies have produced electric baritone guitars since the 1960s, although always in small numbers due to low popularity. Tacoma, Santa Cruz, Taylor, Martin, Alvarez Guitars and others have made acoustic baritone guitars.
Variax was the name of a line of guitars developed and marketed by Line 6 between 2002 and 2023. They differed from typical electric and acoustic guitars in that internal electronics processed the sound from individual strings to model (replicate) the sound of specific guitars and other instruments. The maker claims it was the first guitar family able to emulate the tones of other notable electric and acoustic guitars. It also provided a banjo and a sitar tone. The Variax was available primarily in electric guitar models, but acoustic and electric bass guitar models have also been available in the past.
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.
An extended-range bass is an electric bass guitar with a wider frequency range than a standard-tuned four-string bass guitar.
The sintir, also known as the guembri (الكمبري), gimbri, hejhouj in Hausa language, is a three stringed skin-covered bass plucked lute used by the Gnawa people. It is approximately the size of a guitar, with a body carved from a log and covered on the playing side with camel skin. The camel skin has the same acoustic function as the membrane on a banjo. The neck is a simple stick with one short and two long goat strings that produce a percussive sound similar to a pizzicato cello or double bass.
A multi-neck guitar is a guitar that has multiple fingerboard necks. They exist in both electric and acoustic versions. Examples of multi-neck guitars and lutes go back at least to the Renaissance.
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 or videos introduce one or more tuning techniques, such as:
A nine-string guitar is a guitar with nine strings instead of the commonly used six strings. Such guitars are not as common as the six-string variety, but are used by guitarists to modify the sound or expand the range of their instrument.
