Rubab, robab, or rabab (Pashto / Persian: رُباب, Punjabi: ਰਬਾਬ, Kashmiri: رَبابہٕ, Sindhi: رَبابُ (Arabic script), रबाबु (Devanagari), Azerbaijani / Turkish: Rübab, Tajik / Uzbek рубоб) is a lutelike musical instrument. The rubab is the national musical instrument of Afghanistan, is also commonly played in Pakistan and India mostly by Pashtuns and Balochis, Sindhis, Kashmiris and Punjabis. Variants of the rubab include the Kabuli rebab of Afghanistan, the Rawap of Xinjiang, the Pamiri rubab of Tajikistan and the seni rebab of northern India. 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.
The rubab is known as "the lion of instruments" and is one of the two national instruments of Afghanistan (with the zerbaghali). Classical Afghan music often features this instrument as a key component. Elsewhere it is known as the Kabuli rebab in contrast to the Seni rebab of India. In appearance, the Kabuli rubab looks slightly different from the Indian rubab. It is the ancestor of the north Indian sarod, although unlike the sarod, it is fretted.
The rubab is attested from the 7th century CE. It is mentioned in old Persian books, and many Sufi poets mention it in their poems. It is the traditional instrument of Khorasan[vague] and is widely used in countries such as Afghanistan, Pakistan, Azerbaijan, Iran, Turkey, Iraq, Tajikistan, and Uzbekistan, as well as in the Xinjiang province of northwest China and the Jammu and Kashmir and Punjab regions of northwest India.
The rubab was the first instrument used in Sikhism; it was used by Bhai Mardana, companion of the first guru, Guru Nanak. Whenever a shabad was revealed to Guru Nanak he would sing and Bhai Mardana would play on his rubab; he was known as a rababi. The rubab playing tradition is carried on by Sikhs such as Namdharis.
