Soprano The mandolin is the soprano member of the mandolin family, as the
violin is the soprano member of the
violin family. Like the violin, its scale length is typically about . Modern American mandolins modelled after Gibsons have a longer
scale, about . The strings in each of its double-strung
courses are tuned in unison, and the courses use the same tuning as the violin: G3–D4–A4–E5.
Piccolo The
piccolo or
sopranino mandolin is a rare member of the family, tuned one octave above the mandola and one fourth above the mandolin (C4–G4–D5–A5); the same relation as that of the
piccolo (to the
western concert flute) or
violino piccolo (to the
violin and
viola). One model was manufactured by the Lyon & Healy company under the Leland brand. A handful of modern instruments makers build piccolo mandolins.
Alto The
mandola, termed the
tenor mandola in Britain and Ireland and
liola or
alto mandolin in continental Europe, is tuned a fifth below the mandolin, in the same relationship as that of the
viola to the
violin. Some also call this instrument the "alto mandola". Its scale length is typically about . It is normally tuned like a viola (perfect fifth below the mandolin) and tenor banjo: C3–G3–D4–A4.
Tenor The
octave mandolin (US and Canada), termed the
octave mandola in Britain and Ireland and
mandola in continental Europe, is tuned an octave below the mandolin: G2–D3–A3–E4. Its relationship to the mandolin is that of the
tenor violin to the violin, or the
tenor saxophone to the
soprano saxophone. Octave mandolin scale length is typically about , although instruments with scales as short as or as long as are not unknown. The instrument has a variant off the coast of South America in Trinidad, where it is known as the
bandol, a flat-backed instrument with four courses, the lower two strung with metal and nylon strings. The
Irish bouzouki, though not strictly a member of the mandolin family, has a reasonable resemblance and similar range to the octave mandolin. It derives from the
Greek bouzouki (a long-necked lute), constructed like a flat-backed mandolin and uses fifth-based tunings, most often G2–D3–A3–D4. Other tunings include: A2–D3–A3–D4, G2–D3–A3–E4 (an octave below the mandolin—in which case it essentially functions as an octave mandolin), G2–D3–G3–D4 or A2–D3–A3–E4. Although the Irish bouzouki's bass course pairs are most often tuned in unison, on some instruments one of each pair is replaced with a lighter string and tuned in octaves, similar to the 12-string
guitar. While occupying the same range as the octave mandolin/octave mandola, the Irish bouzouki is theoretically distinguished from the former instrument by its longer scale length, typically from , although scales as long as , which is the usual Greek bouzouki scale, are not unknown. In modern usage, however, the terms "octave mandolin" and "Irish bouzouki" are often used interchangeably to refer to the same instrument. The modern
cittern may also be loosely included in an "extended" mandolin family, based on resemblance to the flat-backed mandolins, which it predates. Its own lineage dates it back to
the Renaissance. It is typically a five course (ten-string) instrument having a scale length between . The instrument is most often tuned to either D2–G2–D3–A3–D4 or G2–D3–A3–D4–A4, and is essentially an
octave mandola with a fifth course at either the top or the bottom of its range. Some luthiers, such as Stefan Sobell, also refer to the octave mandola or a shorter-scaled Irish bouzouki as a cittern, irrespective of whether it has four or five courses. Other relatives of the cittern, which might also be loosely linked to the mandolins (and are sometimes tuned and played as such), include the 6-course/12-string
Portuguese guitar and the 5-course/9-string
waldzither.
Baritone/Bass The
mandocello is classically tuned to an octave plus a fifth below the mandolin, in the same relationship as that of the
cello to the violin, its strings being tuned to C2–G2–D3–A3. Its scale length is typically about . A typical violoncello scale is . during a concert in
Rome, 1889 The
mandolone was a
Baroque member of the mandolin family in the bass range that was surpassed by the mandocello. It was part of the Neapolitan mandolin family. The Greek
laouto or
laghouto (long-necked lute) is similar to a mandocello, ordinarily tuned C3/C2–G3/G2–D3/D3–A3/A3 with half of each pair of the lower two courses being tuned an octave high on a lighter gauge string. The body is a staved bowl, the saddle-less bridge glued to the flat face like most ouds and lutes, with mechanical tuners, steel strings, and tied gut frets. Modern laoutos, as played on Crete, have the entire lower course tuned to C3, a
reentrant octave above the expected low C. Its scale length is typically about . The Algerian
mandole was developed by an Italian
luthier in the early 1930s, scaled up from a mandola until it reached a scale length of approximately 25 to 27 inches. It is a flatback instrument, with a wide neck and 4 courses (8 strings), 5 courses (10 strings) or 6 courses (12 strings), and is used in Algeria and Morocco. The instrument can be tuned as a guitar,
oud, or mandocello, depending on the music it will be used to play and player preference. When tuning it as a guitar the strings will be tuned (E2) (E2) A2 A2 D3 D3 G3 G3 B3 B3 (E4) (E4); strings in parentheses are dropped for a five- or four-course instrument. Using a common Arabic oud tuning D2 D2 G2 G2 A2 A2 D3 D3 (G3) (G3) (C4) (C4). For a mandocello tuning using fifths C2 C2 G2 G2 D3 D3 A3 A3 (E4) (E4).
Mandobass The
mandobass is the bass version of the mandolin, just as the
double bass is the bass to the violin. Like the double bass, it most frequently has four single strings, rather than double courses—and like the double bass, it is most commonly tuned to
perfect fourths rather than fifths like most mandolin family instruments: E1–A1–D2–G2,. These were made by the Gibson company in the early 20th century and were never very common. A smaller scale four-string mandobass, usually tuned in fifths: G1–D2–A2–E3 (two octaves below the mandolin), though not as resonant as the larger instrument, was often preferred by players as easier to handle and more portable. Reportedly, however, most
mandolin orchestras preferred to use the ordinary
double bass, rather than a specialised mandolin family instrument. Calace and other Italian makers predating Gibson also made mandolin-basses. The relatively rare eight-string mandobass, or "tremolo-bass", also exists, with double courses like the rest of the mandolin family, and is tuned either G1–D2–A2–E3, two octaves lower than the mandolin, or C1–G1–D2–A2, two octaves below the mandola. == Variations ==
