Sarod
The sarod (or sarode) (सरोद) is a lute-like 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.
Origins
The sarod is believed by some to have descended from the Afghan rubab, a similar instrument originating in Central Asia and Afghanistan.
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 an 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.
