The sarod (or sarode) (सरोद) is a stringed instrument of India, used mainly in Indian classical music. Along with the sitar, it is among the most popular and prominent instruments in Hindustani classical music. The sarod is known for a deep, weighty, introspective sound, in contrast with the sweet, overtone-rich texture of the sitar, with sympathetic strings that give it a resonant, reverberant quality. It is a fretless instrument able to produce the continuous slides between notes known as meend (glissandi), which are important in Indian music.
The sarod is widely believed to have descended from the Afghan rubab, a similar instrument originating in Central Asia and Afghanistan. Many scholars of Indian classical music believe that sarod is a combination of the ancient Chitra veena, the medieval Rabab and modern Sursingar. Some scholars even contend that a similar instrument may have existed about two thousand years ago in ancient India during the ages of the Gupta kings. In fact, a Gupta period coin depicts the great king Samudragupta playing a Veena, which many believe to be the precursor of the Sarod. Traces of similar Rabab style instruments can also be found in southern India, especially in the states of Tamil Nadu, Kerala and Karnataka, where it is known as the Swarbat. The folk Rabab, an instrument popular in north India, had a wooden fingerboard, its strings were made of silk, cotton or gut, and it was played with a wooden pick. In history, reference is also made to a Sharadiya Veena from which the name Sarod may have been derived.
The word sarod roughly translates to "beautiful sound" or "melody" in Persian, one of the many languages spoken in Afghanistan. Although the sarod has been referred to as a "bass rubab" its tonal bandwidth is actually considerably greater than that of the rubab, especially in the middle and high registers. Lalmani Misra opines in his Bharatiya Sangeet Vadya that the sarod is a combination of the ancient chitra veena, the medieval rubab and modern sursingar. There is also speculation that the oud may be the origin of the sarod.
