Thiruvaiyaru (also spelt as Tiruvaiyaru) is a panchayat town in Thanjavur District. It is situated on the banks of the river Kaveri, 13 km from Thanjavur, Thiruvaaiyaru has an old Siva temple dedicated to Panchanatheeswar. Though pilgrims flock to this temple throughout the year, Thiruvaiyaru is more renowned for its association with Saint Thyagaraja. Thyagaraja was one of the greatest composers of Carnatic music. He was a prolific composer and highly influential in the development of the South Indian classical music tradition. Tyagaraja composed thousands of devotional compositions, most in praise of Lord Rama — many of which remain popular today. The cancellation depicts musical instruments 'Veena' and 'Kartal' (Kartal is made of wooden blocks with holes for the fingers and circular copper plates. Pairs of Kartals are played with both hands. Kartals usually accompany religious music in India played during the festivals and even near the holy places.)
