Lead each technique with your head and eyes and visualize your opponent making the attack in your mind. Respond with your own techniques with the same intensity that you would defending and countering the attack in real life. By doing this, observers of your kata can see the battle develop before them. Whether you do your kata slow or fast, remember that each kata has it s own rhythm. The rhythm of the kata is dictated by the battle that it represents.
Some movements are quite fast, while others are slow.
Stay focused throughout the kata. Your Sensei or a judge in tournament can immediately spot it when your mind is diverted. Remember to breathe correctly. When preparing to do a technique, inhale. Upon executing the technique, breathe out sharply.
