Damaru
Many say that the sound produced by beating the dramaru was passed onto lord Ganesha, who added more sound and thus—music was born. Some even suggest that it stands for words of the Vedas.
Damaru, which looks like a small drum appearing in the form similar to that of an hour-glass is often attributed to the lord's famous dancing posture—the Nataraja.
It is believed by many that the damaru produced the first dhwani (sound) also known as 'nada' in the universe. It was born in the void and Shiva danced to the rhythm of damaru, which led to the creation of this universe.
