Nataraja Ramakrishna's teacher (Rajamma of the Devadasi tradition from Sri Kalahasti) taught him to attune his voice with the tinkling noise that reverberated in the temple precincts when the temple pillar was struck with a stone.  This helped him in later years to work on the "vibration theory" of sound and its impact on dance.
