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 musical instrument classification, string instruments or chordophones, are musical instruments that produce sound from vibrating strings when a performer plays or sounds the strings in some manner.
The mandola (US and Canada) or tenor mandola (Ireland and UK) is a fretted, stringed musical instrument. It is to the mandolin what the viola is to the violin: the four double courses of strings tuned in fifths to the same pitches as the viola (C3-G3-D4-A4), a fifth lower than a mandolin. The mandola, though now rarer, is an ancestor of the mandolin. (The word mandolin means little mandola.)
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 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 mandocello is a plucked string instrument of the mandolin family. It is larger than the mandolin, and is the baritone instrument of the mandolin family. Its eight strings are in four paired courses, with the strings in each course tuned in unison. Overall tuning of the courses is in fifths like a mandolin, but beginning on bass C (C2). It can be described as being to the mandolin what the cello is to the violin.
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.
Edwin Ellsworth Peabody was an American banjo player, instrument developer, and musical entertainer whose career spanned five decades. He was the most famous plectrum banjoist of his era.
A course, on a stringed musical instrument, is either one string or two or more adjacent strings that are closely spaced relative to the other strings, and typically played as a single string. The strings in each multiple-string course are typically tuned in unison or an octave.
The electric mandolin is an instrument tuned and played as the mandolin and amplified in similar fashion to an electric guitar. As with electric guitars, electric mandolins take many forms. Most common is a carved-top eight-string instrument fitted with an electric pickup in similar fashion to many archtop semi-acoustic guitars. Solid body mandolins are common in 4-, 5-, and 8-string forms. Acoustic electric mandolins also exist in many forms.
The mandolin-banjo is a hybrid instrument, combining a banjo body with the neck and tuning of a mandolin. It is a soprano banjo. It has been independently invented in more than one country, variously being called mandolin-banjo,banjo-mandolin,banjolin and banjourine in English-speaking countries, banjoline and bandoline in France, and the Cümbüş in Turkey.
The scale length of a string instrument is the maximum vibrating length of the strings that produce sound, and determines the range of tones that string can produce at a given tension. It is also called string length. On instruments in which strings are not "stopped" or divided in length, it is the actual length of string between the nut and the bridge.
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.
Plucked string instruments are a subcategory of string instruments that are played by plucking the strings. Plucking is a way of pulling and releasing the string in such a way as to give it an impulse that causes the string to vibrate. Plucking can be done with either a finger or a plectrum.
On a stringed instrument, a break in an otherwise ascending order of string pitches is known as a re-entry. A re-entrant tuning, therefore, is a tuning which does not order all the strings from the lowest pitch to the highest pitch.
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:
The Tahitian ukulele is a short-necked fretted lute with eight nylon strings in four doubled courses, native to Tahiti and played in other regions of Polynesia. This variant of the older Hawaiian ukulele is noted by a higher and thinner sound and an open back, and is often strummed much faster.
