Technique for producing sound by pressing the tip of the tongue against the superior alveolar ridge with the mouth open and bringing the tongue down, thus creating a click. Pitch can be varied by adjusting the length of the phonatory tube by pursing the lips, by lifting the palate, and by making other small opening and closing adjustments in the mouth. Recognizable tunes can be clicked. Dynamics can also vary, principally due to the amount of pressure in the tongue tip and the forcefulness with which it is pulled away from the alveolar ridge.
