A mandolin is a stringed musical instrument in the lute family and is generally plucked with a plectrum. 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.
In music, there are two common meanings for tuning:
Pythagorean tuning is a system of musical tuning in which the frequency ratios of all intervals are based on the ratio 3:2. This ratio, also known as the "pure" perfect fifth, is chosen because it is one of the most consonant and easiest to tune by ear and because of importance attributed to the integer 3. As Novalis put it, "The musical proportions seem to me to be particularly correct natural proportions." Alternatively, it can be described as the tuning of the syntonic temperament in which the generator is the ratio 3:2, which is ≈702 cents wide.
In music theory, an interval is a difference in pitch between two sounds. An interval may be described as horizontal, linear, or melodic if it refers to successively sounding tones, such as two adjacent pitches in a melody, and vertical or harmonic if it pertains to simultaneously sounding tones, such as in a chord.
The bouzouki, also spelled buzuki or buzuci, 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. There are two main types of 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 immigrants 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.
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 twelve-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.
A semitone, also called a half step or a half tone, is the smallest musical interval commonly used in Western tonal music, and it is considered the most dissonant when sounded harmonically. It is defined as the interval between two adjacent notes in a 12-tone scale. For example, C is adjacent to C♯; the interval between them is a semitone.
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 bandurria is a plucked chordophone from Spain, similar to the mandolin, primarily used in Spanish folk music, but also found in former Spanish colonies.
The Irish bouzouki is an adaptation of the Greek bouzouki. The newer Greek tetrachordo bouzouki was introduced into Irish traditional music in the mid-1960s by Johnny Moynihan of the folk group Sweeney's Men. Alec Finn, first in the Cana Band and subsequently in De Dannan, introduced the first Greek trichordo bouzouki into Irish music.
Chorus is an audio effect that occurs when individual sounds with approximately the same time, and very similar pitches, converge and are perceived as one. While similar sounds coming from multiple sources can occur naturally, as in the case of a choir or string orchestra, it can also be simulated using an electronic effects unit or signal processing device.
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.
Quarter-comma meantone, or 1⁄4-comma meantone, was the most common meantone temperament in the sixteenth and seventeenth centuries, and was sometimes used later. In this system the perfect fifth is flattened by one quarter of a syntonic comma (81:80), with respect to its just intonation used in Pythagorean tuning ; the result is 3/2 × 1⁄4 = 4√5 ≈ 1.49535, or a fifth of 696.578 cents. This fifth is then iterated to generate the diatonic scale and other notes of the temperament. The purpose is to obtain justly intoned major thirds. It was described by Pietro Aron in his Toscanello de la Musica of 1523, by saying the major thirds should be tuned to be "sonorous and just, as united as possible." Later theorists Gioseffo Zarlino and Francisco de Salinas described the tuning with mathematical exactitude.
The octave mandolin 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.
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.
The mandore is a musical instrument, a small member of the lute family, teardrop shaped, with four to six courses of gut strings and pitched in the treble range. Considered a French instrument, with much of the surviving music coming from France, it was used across "Northern Europe" including Germany and Scotland. Although it went out of style, the French instrument has been revived for use in classical music. The instrument's most commonly played relatives today are members of the mandolin family and the bandurria.
Among alternative guitar-tunings, regular tunings have equal musical intervals between the paired notes of their successive open strings.
The tambura is a stringed instrument that is played as a folk instrument in Bosnia and Herzegovina, Bulgaria, Croatia, North Macedonia, and Serbia. It has doubled steel strings and is played with a plectrum, in the same manner as a mandolin.
A guitalin is a Northern American folk instrument that is a part of the lute family, having four courses of strings. Its fourth course is tuned to an octave while the remaining courses are tuned in unisons. The instrument can be either finger picked or plucked with a plectrum. It was invented in October 1962 by Lyle Mayfield of Greenville, Illinois. The guitalin is a non-traditional, hybrid folk instrument, as it incorporates features of multiple traditional folk instruments into one. While the original tuning consisted of a G chord in root position, the standard tuning of the guitalin which was adopted is a C chord in second inversion. Another common tuning is a second inversion G chord.
