The origins of Indian classical music can be found from the oldest of scriptures, part of the Hindu tradition, the Vedas. The Samaveda, one of the four Vedas, describes music at length. The Samaveda was created out of Rigveda so that its hymns could be sung as Samagana; this style evolved into jatis and eventually into ragas. Indian classical music has its origins as a meditation tool for attaining self realization.
Indian classical music has one of the most complex and complete musical systems ever developed. Like Western classical music, it divides the octave into 12 semitones of which the 7 basic notes are Sa Re Ga Ma Pa Dha Ni Sa, in order, replacing Do Re Mi Fa So La Ti Do.
Indian classical music is monophonic in nature and based around a single melody line which is played over a fixed drone. The performance is based melodically on particular ragas and rhythmically on talas
