About MandolinA mandolin (Italian: mandolino pronounced [mandoˈliːno]; literally "small mandola") 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 (10 strings) and six (12 strings) course versions also exist. The courses are typically tuned in an interval of perfect fifths, with the same tuning as a violin (G3, D4, A4, E5). Also like the violin, it is the soprano member of a family that includes the mandola, octave mandolin, mandocello and mandobass. There are many styles of mandolin, but the three most common types are the Neapolitan or round-backed mandolin, the archtop mandolin and the flat-backed mandolin.
