Tyagaraja began his musical training at an early age under Sonthi Venkata Ramanayya, the chief vidwan in the court of Thanjavur ruler
Thuljaji, where Tyagaraja's father Ramabrahmam also worked. Tyagaraja hero-worshipped the celestial sage
Narada; a reference to this is Tyagaraja's krithi
Vara Nārada (rāga Vijayaśrī, Ādi tāḷam). Legend has it that a hermit taught him a mantra invoking Narada, and Tyagaraja, meditating on this mantra, received a vision of Narada and was blessed with the book
Svarārnavam by the sage. Tyagaraja was said to have mastered the nuances of music from this book. Tyagaraja regarded music as a way to experience divinity. His compositions focused not only on the technicalities of classical music, but also on the expression (bhāva). He composed his first kriti, "Namo Namo Raghavaaya" in Sanskrit, in the Desika Todi
raga and inscribed it on the walls of his house. His compositions are mainly of a devotional (
bhakti) and philosophical nature. His songs feature himself usually either in an appeal to his deity of worship (primarily
Rama), in musings, in narratives, giving a message to the public. He introduced the concept of saṇgati into the sāhityaṃ of a krithi, that was seen as a paradigm shift in Carnatic Classical Music. He is also known for composing kritis that depict ninda stuti (lovingly/flatteringly scolding the divine (also seen in compositions of
Bhadrachala Ramadasu). He has also composed krithis in praise of Krishna, Shiva, Devi, Ganesha, Muruga, Saraswati, and Hanuman. Tyagaraja's musical genius spread all across Thanjavur and its principalities (of which Thiruvarur and Thiruvaiyaru were also a part of) until it reached the king of Thanjavur,
Serfoji II (also called Sarabhoji II). The king sent an invitation, along with many gifts, inviting Tyagaraja to attend the royal court. Tyagaraja, however, was not inclined towards a career at the court, as he felt it would chain his creativity and also his pursuit of the divine and rejected the invitation outright. He was said to have composed the krithi
Nidhi Chala Sukhama (నిధి చాల సుఖమా) ( "Does wealth bring happiness?") on this occasion. Tyagaraja was always immersed in his devotion to Rama and led a spartan way of life. Tyagaraja willingly taught music to anyone who approached him, thus earning him many disciples across various stages of his life. Prominent ones among them include
Venkataramana Bhagavathar and Krishnaswamy Bhagavathar (the father-son duo of
Walajapet), Thanjavur S Ramarao (who also happened to be his cousin; not to be confused with the namesake,
T. Rama Rao (administrator)),
Veena Kuppayyar,
Manambuchavadi Venkatasubbayyar,
Subbaraya Sastri (son of
Shyama Sastri). Some of these disciples carefully codified his compositions on palm leaves and copper plates. Most of Tyagaraja's kritis are in vernacular language and thus gained immense popularity because of the ease with which they could be learnt and sung. Tyagaraja also composed many kritis in Sanskrit. ==Preservation of compositions==
