The classical guitar is a member of the guitar family used in classical music and other styles. An acoustic wooden string instrument with strings made of gut or nylon, it is a precursor of the modern acoustic and electric guitars, both of which use metal strings. Classical guitars derive from the Spanish vihuela and gittern of the fifteenth and sixteenth century. Those instruments evolved into the seventeenth and eighteenth-century baroque guitar—and by the mid-nineteenth century, early forms of the modern classical guitar.
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 lute is any plucked string instrument with a neck and a deep round back enclosing a hollow cavity, usually with a sound hole or opening in the body. It may be either fretted or unfretted.
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 metal strings tuned in unison, thus giving a total of 8 strings, although five and six course versions also exist. 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.
String instruments, stringed instruments, or chordophones are musical instruments that produce sound from vibrating strings when a performer plays or sounds the strings in some manner.
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.
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 vihuela is a 15th-century fretted plucked Spanish string instrument, shaped like a guitar but tuned like a lute. It was used in 15th- and 16th-century Spain as the equivalent of the lute in Italy and has a large resultant repertory. There were usually five or six doubled strings.
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.
The cavaquinho is a small Portuguese string instrument in the European guitar family, with four wires or gut strings.
The term requinto is used in both Spanish and Portuguese to mean a smaller, higher-pitched version of another instrument. Thus, there are requinto guitars, drums, and several wind instruments.
A tiple, is a plucked typically 12-string chordophone of the guitar family. A tiple player is called a tiplista. The first mention of the tiple comes from musicologist Pablo Minguet e Irol in 1752. Although many variations of the instrument exist, the tiple is mostly associated with Colombia, and is considered the national instrument. The Puerto Rican version characteristically has fewer strings, as do variants from Cuba, Mallorca, and elsewhere among countries of Hispanic origin.
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 cuatro is a family of Latin American string instruments played in Puerto Rico, Venezuela and other Latin American countries. It is derived from the Spanish guitar. Although some have viola-like shapes, most cuatros resemble a small to mid-sized classical guitar. In Puerto Rico and Venezuela, the cuatro is an ensemble instrument for secular and religious music, and is played at parties and traditional gatherings.
There are many varieties of ten-string guitar, including:
The Guitarrón Chileno is a guitar-shaped plucked string instrument from Chile, with 25 or 24 (rarely) strings. Its primary contemporary use is as the instrumental accompaniment for the traditional Chilean genre of singing poetry known as Canto a lo Poeta, though a few virtuosi have also begun to develop the instrument's solo possibilities.
The viola amarantina is a stringed musical instrument from Amarante, Northern Portugal. It is also named viola de dois corações because of the two heart-shaped frontal openings. It has 10 strings in 5 courses. The strings are made of steel. It is tuned A3 A3, F# F#, B2 B3, G2 G3, D2 D3.
Viola da terra is a stringed musical instrument from the islands of the Azores, closely associated with the saudade genre of Portuguese music. Its 12 or 15 metal strings are arranged in either five or six courses.
The viola da Terceira is a stringed musical instrument of the guitar family, from the Portuguese islands of the archipelago of the Azores, associated with the island of Terceira.
