Carnatic Music is one of world's oldest and richest musical traditions. It primarily comprises a monophonic song based on improvised variations. The melody infused ragas called 'alapana' are introduced and developed gradually, with the embellishment much faster and shorter. It begins with 'Varnam' a warm up of sort for the musicians, followed by exchange of ragas and thalas, intermixed with krithis and pallavi. Emphasis is more on the voice than on instrument as it is said to have the ability to bring out the gradation of the composition.
