Music has always been an important part of Indian life. The range of musical phenomenon in India extends from simple melodies to what is one of the most well-developed "systems" of classical music in the world. There are references to various string and wind instruments, as well as several kinds of drums and cymbals, in the Vedas. Some date the advent of the system of classical Indian music to Amir Khusro. Muslim rulers and noblemen freely extended their patronage to music. In the courts of the Mughal emperors, music is said to have flourished, and the Tansen was one of the jewels of Akbar's court.
