 At the end of the 6th century, a wood topped version of the Persian-styled instrument was constructed by al Nadr, called "ūd", and introduced from Iraq to Mecca.This Persian-style instrument was being played there in the seventh century.Sometime in the seventh century it was modified or "perfected" by Mansour Zalzal, and the two instruments (barbat and "ūd shabbūt") were used side by side into the 10th century, and possibly longer.
