The Shurangiz (Persian: شورانگیز, meaning tumult-exciting‎) is an Iranian musical instrument, based on the setar, developed in the 20th century. It differs from the setar by having skin as part of the soundboard and in the number of strings. It has a unique sound table consisting of a wooden panel suspended in the center of a membranous outer section, six strings, a longer finer fingerboard and increased number of frets comparing with its original prototype setar.
