Context: Rubab, Robab or Rabab (Pashto / Persian: رُباب, Kashmiri : رَبابہٕ, Sindhi: روباب (Nastaleeq), रबाब (Devanagari), Azerbaijani / Turkish: Rübab, Tajik / Uzbek рубоб) is a lute-like musical instrument. The rubab, one of the national musical instruments of Afghanistan, is also commonly played in Pakistan and India by Pashtuns, Balochis, Sindhis, Kashmiris and Punjabis. The rubab has three variants, the Kabuli rebab of Afghanistan, the Seni rebab of northern India and the Pamiri rubab of Tajikistan. The instrument and its variants spread throughout West, Central, South and Southeast Asia. The Kabuli rebab from Afghanistan  derives its name from the Arabic rebab and is played with a bow while in Central Asia and the Indian subcontinent, the instrument is plucked and is distinctly different in construction. In general, the body is carved out of a single piece of wood, with a head covering a hollow bowl which provides the sound-chamber. The bridge sits on the skin and is held in position by the tension of the strings. It has three melody strings tuned in fourths, two or three drone strings and up to 15 sympathetic strings. The instrument is traditionally made from the trunk of a mulberry tree, the head from an animal skin such as goat, and the strings from the intestines of young goats (gut) or nylon.
