A fretless Middle Eastern lute. Played with a uniquely shaped pick called a plectrum (or risha or rizap.) Generally has five pairs of strings and a single bass string with a deeply rounded back and flat top. Also spelled ud.
(Pronounced "ood" where the "oo" sound is like that in "moon".) Sometimes spelled Ud. This is a musical instrument commonly used in Arabic, Turkish, and Armenian music which was the forerunner of the European lute. It has 11 strings and no frets. The melody is produced through plucking the strings.
