Sudeshna is a musician, playing the rich tradition of north Indian classical music. Her instrument is the sarod. The more than one meter long, nineteen strings sarod is a descendant of a mid-Asian instrument, the rabab, witch was modified seven generation ago, to better suit Indian music. Children usually begin to acquaint with the instrument at early age of four, and practice each passage or movement on the instrument for many years. In contrary to sitar, the places of the individual notes on the fretboard of the sarod are not set, as with the violin or cello. This particularity, and similarity with bowed western and Indian instruments is an important necessity for Indian music, knowing more notes, or micro tones than the western scale.

Sarod, and music generally, played in India is inherited from father to son, meaning that there are very few female musicians in the country. There are only three known female sarod players in the world, and Sudeshna is one of them.

Sudeshna began to learn at the age of four from her father Pandit Shri Krishnamohan Bhattacharya, who is respected not only because of his sarod, but also because of his vocal knowledge in dhrupad style. According to the tradition, Pandit Shri Krishnamohan Bhattacharya learnt from his father, Pandit Biswanath Bhattacharya, who was a great esraj player, and the great sarod maestro Pandit Radhika Mohan Maitra. After studying from her father, Sudeshna gave her first public recital at the age of seven. and in the same year she started participating in musical competition too.
