[1] It 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.
The sarod emerged in India during the early 19th century as an evolved form of the Afghani rubāb, commonly played in the regions to the east of Delhi, inhabited by Afghan communities.
These enhancements facilitated longer-lasting notes and the ability to execute the intricate embellishments characteristic of dhrupad and khyal styles of music.
[6][7] Lalmani Misra opines in his Bharatiya Sangeet Vadya that the sarod is a combination of the ancient chitravina, the medieval rubab and modern sursingar.
It was his descendants, notably his grandson Ghulam Ali Khan Bangash, a court musician in Gwalior, who changed the rubab into the sarod we know today.
The sarod in its present form dates back to approximately 1820, when it started gaining recognition as a serious instrument in Rewa, Shahjahanpur, Gwalior and Lucknow.
Both Amjad Ali Khan and Buddhadev Dasgupta have introduced minor changes to their respective instruments which have become the design templates for their followers.
The Maihar sarod lends itself extremely well to the presentation of alap with the four jod strings providing a backdrop for the ambiance of the raga.
The strings are plucked with a triangular plectrum (java) made of polished coconut shell, ebony, cocobolo wood, horn, cowbone, Delrin or other such materials.
Radhika Mohan Maitra, for example, used the index, middle and ring finger of his left hand to stop the string, just like followers of Allauddin Khan do.
Amjad Ali Khan, while a member of approximately the same stylistic school as Radhika Mohan, prefers to use just the index and middle fingers of his left hand.
