A mandolin is an italian stringed musical instrument in the lute family
and is generally plucked with a pick. It most commonly has four courses
of doubled strings tuned in unison, thus giving a total of eight
strings. A variety of string types are used, with steel strings being
the most common and usually the least expensive. 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.
