Sound (and Darknes)

THUNK! Yeah, the sound of a hit -- that is, what we love with throwing. This is music!

Beside the joy, sound has technical aspects as well. One can use sound to extract information, the amount almost only limited by the detectors, not by the sound itself.

E.g. analysing the sound of an earthquake, is the only way to find out the interior structure of the earth. Our view of the interior of the earth becomes more and more refined. The mathematical means to do so is the Fourier Analysis. An other example are machines, which detect the defect of an automobile motor, just by analysing the sound of the motor.

The same is true for throwing. You will register the effect especially, if you are throwing in the dark. Do you? You see the target only as a sillouhett, and for judging the distance, you have to know the area from daytime. By listening to the sound of the hit, you can clearly judge the quality of the throw. Better than with the eyes!

Throwing in the dark has the following nice optical side effect: You see the sparks if occationally one steel hits the other.

As you see, sound contains an astonishing plenty of information. One thing is the joy, the sound carries. Another thing is the purpose.

Sound has to do with time. Rotation (of the knife) has to do with rythm. The follow through makes music out of a throw. It connects the moment from the idea to throw with the moment of the hit to one single peace of ongoing without time. (Compare chapter Technique - Follow Through )
