Carnatic music is a system of music commonly associated with the southern part of the Indian subcontinent, with its area roughly confined to five modern states of India: Andhra Pradesh, Karnataka, Kerala, Telangana and Tamil Nadu.
The basic elements of śruti (the relative musical pitch), swara (the musical sound of a single note), rāga (the mode or melodic formulæ), and tala (the rhythmic cycles) form the foundation of improvisation and composition in Carnatic music.
Trinity of Carnatic music
The contemporaries Tyagaraja , Muthuswami Dikshitar and Syama Sastri are regarded as the Trinity of Carnatic music because of the quality of Syama Sastri’s compositions, the varieties of compositions of Muthuswami Dikshitar, and Tyagaraja’s prolific output in composing kritis.
Today, Carnatic music is presented by musicians in concerts or recordings, either vocally or through instruments. Carnatic music itself developed around musical works or compositions of phenomenal composers
