Sound-Offs (Ki Hap)

A vocal explosion we refer to as sounding off is a very important element in Tang Soo Do for several reasons. Physiologically, the sudden expulsion of air from the lungs tightens the abdominal muscles against any counter attack and thus lessens it's affect. It also clears the lungs for the new intake of oxygenated air; essential to supplying the blood with burning power for muscle tissue. This will help increase stamina. Psychologically, the shout serves to startle and demoralize ones opponent giving one a momentary advantage. Furthermore shouting a command clarifies in the mind of the shouter what he is doing. It focuses his/her thoughts and so makes him act with greater incisiveness. Exhaling at the point of impact will help to maximize power and accelerate the blow. Students should sound off from the abdomen on any motion out of a chun bee stance, on all turns, on finishing motions in punching or kicking drills and when directed by the instructor. Most of our hyungs contain at least one sound-off at appropriate places in the form.
