When a very large gong is rubbed at the right rate and
pressure it hums and
makes the coolest sound... it can be heard miles away if the temple is
constructed to reflect the sound of it. I remember one such temple
called Wat Nong Bua in Ubon Ratchathani. The gong was large like this
one and could be heard at the other end of town! Enjoy the video - this
girl does a great job of making the gong hum.
