The rebab (Arabic: ربابة, rabāba, variously spelled rebap, rubob, rebeb, rababa, rabeba, robab, rubab, rebob, etc) is the name of several related string instruments that independently spread via Islamic trading routes over much of North Africa, Southeast Asia, the Middle East, and parts of Europe. The instrument is typically bowed, but is sometimes plucked. It is one of the earliest known bowed instruments, named no later than the 8th century, and is the parent of many bowed and stringed instruments.
