In Hindustani music (North Indian classical music), a gharānā is a system of social organisation in the Indian subcontinent, linking musicians or dancers by lineage or apprenticeship, and more importantly by adherence to a particular musical style.
The word gharana comes from the Hindi word 'ghar' which is derived from the Sanskrit word Griha, which means 'house'. It typically refers to the place where the musical ideology originated; for example, some of the gharanas well known for singing khyals are: Dilli(Delhi), Agra, Gwalior, Indore, Atrauli-Jaipur, Kirana and Patiala. Four famous kathak gharanas are: Lucknow, Atrauli-Jaipur, Benares and Raigarh.
The gharana system in khyal was rooted in the guru–shishya tradition and was similar to the Dhrupad Bani system. The gharana system was greatly influenced by the gradual fall of the Mughal Empire, which forced musicians to move from Delhi to princely states such as Gwalior, Lucknow, Hyderabad, Patiala and Rampur.
The gharanas have distinct styles of presenting the khyal — how much to emphasize and how to enunciate the words of the composition, when to sing the sthayi and antara, whether to sing an unmetered alap in the beginning, what kinds of improvisations to use, how much importance to give to the rhythmic aspect, and so on. However, an individual performer from a gharana may choose to borrow appealing stylistic aspects of another gharana in his or her gayaki (singing style). There are ten prominent khyal gharanas, and they are:[1]
(Rang Rus) Sheikh Ajmal (Miyan Achpal) Mir Qutub Baksh (Miyan Tanras) Haji Muhammed Siddiq Khan, Muzaffar Khan
Members of this gharana approach raagdari with more freedom than the dhrupad-informed gharanas, like Gwalior, Jaipur, and Agra.[3] Emphasis on bhav and exposition are the hallmarks of this style.[4]
