Lord Anjaneya Swami
Sri Sangeetha Anjaneya Swami Temple, Mandaveli, CHENNAI
At one time Lord Anjaneya judged a Veena competition between Sage Thumburu and Sage Narada. After the competition Lord Anjaneya rendered celestial music on a fretless Veena. The divinity of Lord Anjaneya's music was such that Lord Vishnu Himself appeared before Anjaneya and both Sages Thumburu and Narada felt humbled.
Apart from the temple above which is in Mandaveli, there is an ancient 2000 years old temple in Mappedu (Thiruvellore District, Tamil Nadu) called the Singeeswarar Temple that has Lord Anjaneya's idol playing the Veena. This is a temple for Moola Nakshatra.
