Ustad Enayat Khan (Urdu: عنایت خان; (1894–1938) also known as Nath Singh was one of India's most influential sitar and surbahar players in the first decades of the 20th century.
For example, he standardized its physical dimensions and added the upper resonator gourd, which is very popular with today's players (though his own descendants have not been using it).
"[2] In a place rapidly developing into an important North Indian centre of the arts, at a time where interest in national culture was strong fuelled by the struggle for independence, he brought sitar music out from its narrow connoisseur circles to new mass audiences.
[2] Some of Enayat Khan's recordings have been released on CD, on the Great Gharanas: Imdadkhani compilation in RPG/EMI's Chairman's Choice series.
His two sons, noted sitar player Vilayat Khan (1928-2004)[5] and Imrat,[2] were trained in the Imdadkhani gharana style by other members of his extended family.
