India is a land of cultural diversities—and as such, every region in India has its own form of folk music. This rich tradition of folk music is very much alive in not just rural India, but also in metropolitan India. 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. The two major traditions of Indian music are Hindustani and Carnatic. These two major forms have their roots in the Vedic literature of Hinduism. Carnatic music can be traced to the 14th - 15th centuries and thereafter. It has served as the foundation for most music in South India, including folk music, festival music, and social celebrations. Like Hindustani music, it is melodic with improvised variations, but it tends to have more fixed compositions. Hindustani music is the other main Indian classical music tradition. It originated in North India around 13th and 14th centuries. The tradition of Hindustani music dates back to Vedic times where the hymns in the Sama Veda, an ancient religious text, were sung as Samagana and not chanted. In contrast to Carnatic music, the Hindustani classical music was not only influenced by ancient Hindu musical traditions and Vedic philosophy but also by Persian and Islamic elements. Traditional Indian music does not incorporate Western concepts of music such as harmony, counterpoint, chords, or modulation. Instead it relies on two foundational musical elements referred to as raga and tala. The raga forms the fabric of a melodic structure, while the tala measures the time cycle. The raga gives an artist a palette to build the melody from sounds, while the tala provides them with a creative framework for rhythmic improvisation using time. There are references to various string and wind instruments, as well as several kinds of drums and cymbals, in the Vedas. The Sitar is one of the most popular music instruments of North India. It has a long neck with twenty metal frets and six to seven main cords. Below the frets of Sitar are thirteen sympathetic strings which are tuned to the notes of the Raga. A gourd, which acts as a resonator for the strings is at the lower end of the neck of the Sitar.
