Most people refer to this instrument as a 12-string mandolin but strung with triple courses (3-3-3-3) and still tuned G, D, A,E. The extra strings gives the instrument a fuller sound and makes it slightly easier for tremolo picking. There are a coupleof variations on how the instrument can be strung as described below, but once you play a 12-string mandolin it is hard togo back to a regular one.The most famous and traditional mandolin is the Italian Neapolitan mandolin, with the deep round lute like back. Accordingto Franz Jahnel's 'Manual of Guitar Technology' The Sicilian mandolin was similar to the Neapolitan type but has a widerneck because it had 11-strings. The top three courses had triple strings with the lowest string on each course tuned anoctave lower. The lowest course being 'G' was usually just doubled, but the modern instruments have complete triplestringing. (With the body so small, acoustically it wouldn't work so well to have an octave lower G-string. This is probablywhy the G only had double strings).The Mandriola is another name for the instrument but strung slightly different. One of the strings in each of the lowercourses are tuned an octave down. The alternative way to string the instrument is to have one of the strings in each of thelower courses tuned an octave up. The string company Optima did produce two sets of mandriola strings, High Octaveand Low Octave.The more common approach is to have triple courses of the same gauge rather than adding any octave strings, which ispictured to the right.
