For ever, we can feel proud of the advent of Thirugnana Sambandha Peruman. The compositions of the myriad composer Sri Annamacharya, Sri Purandaradasa, Sri Bhadrachala Ramadas, Sri Tyagaraja , Sri Muthuswamy Dikshitar , Sri Syama Sastri and Sri Swati Tirunal show the strength of our cultural heritage. Classical Music in dormant state for several years can be attributed to the limitary attitude of the musicians and lack of conveyance which became a deriment for the Classical Music for its pervasion, making ideations met with vain, leading to the proposal of unwanted postulates. The dormancy started breaking after 14th century with the descent of the myriad composer Sri Annamacharya. Sri Tyagaraja made the dormancy completely broken, duly incorporated the rules of music, making the Classical Music pervasive to the maximum extent. The forgotten nuances came to light during the period of Sri Tyagaraja , thus proving renascence .
Later, many vidwans came under the patronage of kings . Some became Samasthana Vidwans. Sangameswara Sastri , the Samasthana (Veena )Vidwan of Pithapuram delighted Rabindranath Tagore with his melodious music and accompanied him to Shantiniketan. When the Classical Music was already reinforced by the divine composers, M.S.Subbulakshmi made people to experience the fullness of melody. The melody, an undisturbed aspect with the clutch of time ,remains the same and you can only see the change in the way of presentation with passing of time.
In India, Classical Music did not spare even the stones . In some temples ,you can find pillars , from which emanate tones. Like the stone pillars , music from the bamboo flute(Venu,Kuzhal)having an age like the stone, created pillars to support our cultural heritage. To give an age for the origin of Sapta Swaras is unwise.
