About MandolinA mandolin (Italian: mandolino pronounced [mandoˈliːno]; literally "small mandola") is a stringed musical instrument in the lute family and is usually plucked with a plectrum. It commonly has four courses of doubled metal strings tuned in unison (8 strings), although five (10 strings) and six (12 strings) course versions also exist. The courses are typically tuned in a succession 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 three are common, the Neapolitan or round-backed mandolin, the archtop mandolin and the flat-backed mandolin.
