Tzouras is a traditional Greek string instrument, similar to a small lute. It typically has a round body and a long neck, featuring four strings that are usually made of nylon or gut. The instrument is played with a plectrum and is known for its bright, resonant sound, making it popular in various forms of Greek folk music. The tzouras is often associated with the musical genre of Rebetiko, which emerged in the early 20th century. Musicians use the tzouras to accompany singing and dancing, contributing to the lively atmosphere of Greek celebrations and gatherings.
