Gakogui
A non-melodic, double belled idiophone produced from iron pipes. The gakogui is the foundational instrument for all Eʋe ensembles. It guides the ensemble by providing a tempo within a rhythmic framework. The gakogui is also known as tigo (derived from the high bell, ti, and the low bell, go) or gakpevi (feminine version, reffering to the mother bell and the child bell). The gakogui is played with a wooden stick approximately 12-30 cm.
