The santur is a hammered dulcimer of Persian/Iranic origins. The term Santur originally meant 100 strings.
Versions of the santur or hammered dulcimer are used throughout the world. In Eastern Europe, a larger descendant of the hammered dulcimer called the cimbalom is played and has been used by a number of classical composers, including Zoltán Kodály, Igor Stravinsky and Pierre Boulez, and more recently, in a different musical context, by Blue Man Group. The khim is the name of both the Thai and the Khmer hammered dulcimer. The Chinese yangqin is a type of hammered dulcimer that originated in Persia. The santur and santoor are found in the Middle East and India, respectively.
