Robab is one of the oldest plucked string instruments in Iran that is mostly common in the east and south east of Iran. Robab is usually made of wood, skin, gut or nylon thread.
Playing different types of Robab is also common in some other regions of Iran and some neighboring countries. This instrument was used in the 1950s and 1960s in the concerts of Iranian national instruments. In urban concerts, Robab is placed horizontally on the knee (like Barbat or Tar) and it is played by a plectrum.
The Robab which is today used in urban concerts is made of walnut, mulberry or other hardwoods.
This instrument consists of four general parts: belly, chest, neck and head. It has 6 single (or 3 pairs of) main strings and 10, 12 or 14 sympathetic strings which are located under the main strings.
