Mandolin
A mandolin (Italian: mandolino pronounced [mandoˈliːno]; literally "small mandola") is a stringed musical instrument in the lute family and is usually plucked with a plectrum or "pick". 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 normally tuned in a succession of perfect fifths.
