Who among the following musicians is popular for his mastery over the musical instrument Sitar?

The correct answer is Vilayat Khan.

Let us analyze each option to understand why Vilayat Khan is the correct answer:

Understanding the Sitar:
The Sitar is a plucked string instrument originating from the Indian subcontinent. It is one of the most iconic instruments in Hindustani (North Indian) classical music, known for its rich, resonant sound and complex melodic capabilities. It typically has 18–21 strings, including melody strings, drone strings, and sympathetic strings.

Evaluating the Options:

➤ Ali Akbar Khan — He was a legendary Indian classical musician, but he was a maestro of the Sarod, not the Sitar. He is widely regarded as one of the greatest Sarod players of the 20th century.

➤ Vilayat Khan — He was one of the most celebrated Sitar players in the history of Hindustani classical music. Born in 1928 into the Imdadkhani gharana (a renowned musical lineage), he revolutionized the style of Sitar playing by developing the "gayaki ang" (vocal style) on the instrument — making the Sitar sing like a human voice. He was honored with the Padma Bhushan (1964) and Padma Vibhushan (2000), two of India's highest civilian awards, for his extraordinary contributions to music.

➤ Bahadur Khan — He was a distinguished musician known for his mastery over the Sarod. He belonged to the same Imdadkhani gharana but followed the Sarod tradition.

➤ Amjad Ali Khan — He is a world-renowned musician, but he is famous for the Sarod, not the Sitar. He is considered one of the greatest living Sarod players today.

Conclusion:
Among the given options, Vilayat Khan is the musician who is most celebrated and popular for his extraordinary mastery over the Sitar. His contribution to Sitar music is unparalleled, and he is remembered as a titan of Hindustani classical music whose legacy continues to inspire generations of musicians worldwide.
