Arunachala Kavi (1711–1779) was a Tamil poet and a composer of Carnatic music. He was born in Tillaiyadi in Thanjavur District in Tamil Nadu. The three Tamil composers Arunachala Kavi, Muthu Thandavar and Marimutthu Pillai are considered the Tamil Trinity, who contributed to the evolution of Carnatic music.
Arunachala Kavi was fluent in Tamil, Telugu and Sanskrit. He wrote Rama Natakam, a musical drama based on the Ramayana. The music for this musical was composed by two of Arunachala Kavi's disciples, Kothandarama Iyer and Venkatarama Iyer. The songs contain many Tamil proverbs and sayings.
This musical drama was first performed at the Srirangam temple and within a short time it became very popular. Kavirayar was honoured by Maharaja Tulaja, the King of Tanjavur, and by several other patrons of that time. He also composed Seergazhi Sthala Puranam (sirkali), Seergazhi Kovai, Hanumar Pillai Tamil, Ajomukhi Natakam and a few Keertanas.
Some of his famous compositions still popular today are Enpalli kondir iyya, Yaro ivar yaro (Bhairavi), Kanden Kanden Sitayai (Vasanta), Ramanai Kannara Kandane (Mohanam).
