Chembai Sangeetholsavam is an annual Carnatic Music festival held in Guruvayur by the Guruvayur Devaswom (similar to the Thyagaraja Aradhana at Thiruvaiyaru) as a kind of homage toChembai Vaidyanatha Bhagavatar, one of the titans of Carnatic Classical Music.Chembai had conducted the festival in the temple town on his own for about 60 years. He used to invite all the great Carnatic Musicians to perform in the temple town and in course of time, the scale of the festival rivalled the Thiruvaiyaru Thyagaraja Aradhana, which is recognised as one of the most important festivals of homage paid to Saint Thyagaraja. The Guruvayur Devaswom decided to take charge after his death in 1974, and renamed it as Chembai Sangeetholsavam in his memory.About 2000-2500 musicians participate in this festival every year, and it is held for about 12-15 days culminating on the Guruvayur Ekadashi day, when all the musicians sing 5 favourite songs of Chembai and also the Pancharatna Kritis of Thyagaraja. The festival is getting more popular year after year and its scope has increased from three days in its inception to about 12-15 days now.
