Rampur-Sahaswan gharana is a gharana (musical heritage) of Hindustani classical music centred in the North-Uttar Pradesh towns of Rampur and Sahaswan. Ustad Inayat Hussain Khan (1849–1919) was the founder of this gharana.
The gharana find its origins in Ustad Mehboob Khan, the chief khayal singer in the royal court of Rampur State (in present Uttar Pradesh), his tradition was followed by his son Ustad Inayat Hussain Khan (1849–1919) and in turn by Inyat's brothers-in-law, Ustad Haider Khan (1857–1927), and Padma Bhushan Ustad Mushtaq Hussain Khan (1878–1964) (The First recipient of the Padma Bhushan Award) ( , thus all the singers were connected with each other, and gharana was named after their ancestral place, Sahaswan, in present Badaun district. Amongst noted disciples of Padma Bhushan Ustad Mushtaq Hussain are Padma Shri Ustad Ghulam Sadiq Khan, married to his youngest daughter and associated with the Music department of the Delhi University, Sulochana Brahaspati, Sumati Mutatkar, Madhumita Ray, Shanno Khurana and Naina Devi.
Inayat Khan was a child prodigy, and his first married the daughter of Haddu Khan of the Gwalior gharana.
The Rampur-Sahaswan gayaki (style of singing) is closely related to the Gwalior Gharana, which features medium-slow tempos, a full-throated voice and intricate rhythmic play. The gharana style is also known for the diversity and intricacy of the taans (rapidfire elaborations), as well as tarana singing.
