Bouzouki the "tetrachordo" ("four-course") has four pairs of strings. The name "bouzouki" comes from the Turkish word "bozuk", meaning "broken" or "modified", and comes from a particular re-entrant tuning called "bozuk düzen", which was commonly used on its Turkish counterpart, the "saz-bozuk". It is in the same instrumental family as the mandolin and the lute. Originally the body was carved from a solid block of wood, similar to the saz, but upon its arrival in Greece in the early 1910s it was modified by the addition of a staved back borrowed from the Neapolitan mandola, and the top angled in the
Irish bouzouki (or slightly radiused) tops and backs. The Irish bouzouki has also become integrated into some other western European musical traditions over the past forty years. Popularly used in the music of Asturias, Galicia, Brittany, Spain, and even the Scandinavian countries (in fact, there is even now a new Nordic branch of the instrument, having been modified further to suit the unique requirements of those musics). The instrument's role is usually a combination of interwoven accompaniment (usually a mix of open-string drones, two note intervals, bass lines and countermelody) and melodic play.
