Ghatam, one of the ancient percussion instruments, often heard in Carnatic Music concerts, is a mud pot carefully kneaded and uniformally fired. The mouth of the Ghatam is open and is played with two hands, wrists, fingers and nails. The mouth is pressed against the stomach so that when strokes are given, the air inside is set in vibration and gives a deep tone. The player can elicit various volumes and tonal colours by giving the finger strokes at the neck, centre and bottom of outer surface.
