The dilruba is a stringed musical instrument that is similar to the sarangi and is widely used in Indian classical music. It is played with a bow, like a violin, and has sympathetic strings that resonate with the main strings. The instrument has a long, fretted neck and a hollow wooden body that is usually covered with skin. The dilruba is played by sliding the fingers along the strings to produce different pitches, and the sound is produced by bowing the strings with a horsehair bow. It is often used as an accompanying instrument in classical music and devotional music, and its sound is known for its haunting and emotional qualities.
