Masenqo

The masenqo (ማሲንቆ; Tigrinya: ጭራ-ዋጣ (ዋጣ), also known as masinko, is a single-stringed bowed lute commonly found in the musical traditions of Eritrea and Ethiopia. As with the krar, this instrument is used by Ethiopian minstrels called azmaris ("singer" in Amharic) . Although it functions in a purely accompaniment capacity in songs, the masenqo requires considerable virtuosity, as azmaris accompany themselves while singing.

Construction and design
The square or diamond-shaped resonator is made of four small wooden boards glued together, then covered with a stretched parchment or rawhide. The single string is typically made of horse hair, and passes over a bridge. The instrument is tuned by means of a large tuning peg to fit the range of the singer's voice. It may be bowed by either the right or left hand, and the non-bow hand sits lightly on top of the upper part of the string.
