When you snap your fingers, the fingertip hits the pad of the thumb in the palm and makes a smacking sound.
If you do it just right, it can be pretty loud.
Count it with me, five six seven eight.
“Snap Your Fingers” is also a song written by Grady Martin and Alex Zanetis, originally recorded by gospel singer Joe Henderson in 1962.
Finger snapping may be used as a substitute for hand clapping, because you can’t clap and hold a beer at the same time.
Snapping is also done at posh speeches and announcements as it is less disruptive than rowdy hand clapping.
