The most commonly used string folk instrument in Turkey,
the bağlama has seven strings divided into courses of two, two and three from top to bottom. It can be tuned in various ways and takes different names according to region and size: Divan sazı, bozuk, çöğür, kopuz, ırızva, cura, tambura, etc. The cura is the smallest member of the bağlama family: larger than the cura is the tambura, tuned an octave lower. The Divan sazi, the largest instrument in the family, is tuned one octave lower still.
A bağlama has three main parts: the
bowl (called tekne), made from mulberry wood or juniper, beech, spruce or walnut, the spruce sound board (göğüs) and a neck of beech or juniper (sap). The tuning pegs are known as burgu (literally screw). Frets are tied to the neck with fishing line, which allows them to be adjusted. The bağlama is usually played with a mızrap or tezene (similar to a guitar pick) made from cherrywood bark or plastic.
