Tricordia
A tricordia 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. Mandriolas only use unison tuning, while tricordias use either unison tuning or octave tuning.
