Dilruba

Dilruba is a bowed string instrument from North India, closely related to esraj in eastern traditions. In Hindustani music, raag needs sustain, nuance, and the ability to shade pitch, and the dilruba fits naturally because it can hold notes and glide between them with a vocal sweetness. It appears in classical, devotional, and lighter settings where lyric expression matters.

It is built from wood with a skin soundboard and a fretted neck, carrying a set of main strings bowed for melody along with sympathetic strings that add resonance. The right hand bows, while the left hand works the strings against frets for stable intonation with expressive slides. It can serve as a solo voice or accompaniment depending on the context, and what makes it special is the combination of frets for security and a bow for sustain, producing a tender tone that differs from the raw vocal closeness of sarangi and the brighter projection of violin.
