Agra Gharana is a tradition of Hindustani classical vocal music descended from time of Allauddin Khilji of Delhi 1300 AD.
The first known musician of this tradition is Nayak Gopal. The style prevalent then in the Gharana was “Dhrupad-Dhamar”. Ustad Ghagghe Khudabuksh (1790-1880 AD) introduced the “Khayal” style of Gwalior Gharana into Agra gharana which Khudabaksh learnt from Natthan Paribaksh of Gwalior. Furthermore the Khayal style of Atrauli gharana was added in the late 19th century.
The gayaki of the Agra Gharana is a blend of khayal gayaki and Dhrupad - Dhamar. In training, both the khayal and dhrupad components run hand in hand and are not taught in an isolated fashion. This is obvious from the method of singing notes of the Agra Gharana which demands that the projection of voice be more forceful and voluminous than encountered in khayal gayaki. This is the only Gharana that has still continued to sing Dhrupad-Dhamar along with Nom-Tom Alap, Khayal, Thumri, Tappa, Tarana, Hori, Dadra, Ghazal, Kaul, Rasiya etc.
