Ustad Sultan Khan is a maestro on the sarangi, a bowed instrument with a unique, viola-like, harmonically complex tone due to 35 to 40 sympathetic strings running under the three playing strings.

Raga Marwa is played at dusk and conjures up the introverted calm and contemplative mood of that hour. Bhairavi, with its feeling of 'sweet sadness', is played here in a devotional mood, and Sultan Khan develops the melody with great lyricism and delicacy.
