Tembang sunda, also called seni mamaos cianjuran, is a style of classical vocal music that originated in the Priangan highland of western Java. Unlike Sundanese gamelan music, tembang sunda was developed in the court of the regent Kabupaten Cianjur during the Dutch colonial period. The traditional vocal portion is sung free verse poetry, the instrumental accompaniment being performed on kacapi (zither), suling and sometimes, rebab (violin). A more modern, and metrical, form of lyrics exists that is called panambih.
