The ajaeng is a Korean bowed zither traditionally used in shamanistic rituals, in court and folk ensembles to accompany dance, and as an instrument of virtuosity. The seven thick silk strings pass over a very large curved main bridge, and then again over smaller movable bridges that are on the raised top of the instrument.
The rabab is the national instrument of Afghanistan used in ancient court music, as well as modern day art and entertainment music. The Afghan rabab is also found in northern India and Pakistan, probably due to the Afghan rule in those regions in the 18th Century. The rabab was the precursor to the Indian sarod, which is regarded as one of India's most important instruments.
