Rud

The rud (Persian:رود‎‎) is a Persian stringed musical instrument. In Persian, the word means "string". It has been mentioned in classical Persian literature by Rudaki, Hafez, Naser Khusraw, Sanai, Ferdowsi, Nizami and Qatran Tabrizi other poets. The Arabic 'Ud, whose etymology is not yet convincingly explained, may well have been derived from the Persian word rud.
