Tricordia

A tricordia (also trichordia or tricordio) or mandriola is a twelve-stringed variation of the mandolin. The tricordia is used in Mexican folk music, while its European cousin, the mandriola, is used identically to the mandolin. It differs from a standard mandolin in that it has three strings per course. Tricordias only use unison tuning (ggg d'd'd' a'a'a' e"e"e"), while mandriolas use either unison tuning or octave tuning (Ggg dd'd' aa'a' e'e"e").
