The tongue clop is similar to the block click but, since you don't use any suction to get pressure, can take a while to get used to. It can also tire your tongue out at first, but you'll soon get used to it!

To make the sound

1 - Simply, hit your tongue against the bottom of your mouth - that's all there is to it!
2 - To get the pouring water effect, move your lips from being almost pursed to open wide whilst doing consecutive clops
3 - This can also be used for a waterdrop sound, but that's for another tutorial!

With practice you'll be able to get louder and faster, so keep at it.

Peace, love, and half-full glasses
