A mandolin is a 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. Also, like the violin, it is the soprano member of a family that includes the mandola, octave mandolin, mandocello and mandobass.
Archtop mandolin
In 1787, Luigi Bassi played the role of Don Giovanni in Mozart's opera, serenading a woman with a mandolin. This used to be the common picture of the mandolin, an obscure instrument of romance in the hands of a Spanish nobleman.

Piccolo mandolin
The mandola (US and Canada) or tenor mandola (Ireland and UK) is a fretted, stringed musical instrument. It is to the mandolin what the viola is to the violin: the four double courses of strings tuned in fifths to the same pitches as the viola (C3-G3-D4-A4), a fifth lower than a mandolin. The mandola, though now rarer, is an ancestor of the mandolin. (The word mandolin means little mandola.)
