What was kata originally? A mnemonic – a way to remember, when alone, the two-person drills already learned with a teacher.
.
Those two-person drills would each have had a subject, a concept, to work on. For example: how to escape a clothing grab. We still do that today right?
.
Several more drills would be practiced to cover other concepts – punches, kicks, escapes, throws, locks, cranks, and more. Some of these drills would then be combined to create a kata, all built around a central topic. In this case, it might still have been how to escape a clothing grab.
.
After my article about kata having a central theme, there were a few comments that were dismissive of the idea.
.
So, let’s explore it a bit further.
.
Here’s a question: if kata have a central theme, doesn’t that limit us? What happens when an attack doesn’t fit the supposed theme?
.
First, it helps to look at what a “theme” really means. A kata isn’t a grab-bag of random movements. There is usually a thread running through it. Perhaps a focus on close-range striking, seizing, or controlling. That’s a theme, isn’t it?
.
It’s easy to see how this might feel restrictive. If we think every movement only works in one set way, for one type of attack, then yes, we would be trapped.
.
But in reality, the theme is a guide.
.
It gives us direction, not restriction. Think of it like a school teacher setting a lesson. The lesson may emphasize a certain idea, but the principles within it can be applied in many ways.
.
Here’s an analogy outside of the martial arts. I’ve taught both basic driving and advanced driver training, so I know how complex real-world situations can be.
.
I might set a lesson around a specific maneuver, say a reverse around a corner. That’s the “theme” of the lesson.
.
But before you can get to the safe practice area, the student has to handle everything else on the road: traffic, pedestrians, signals, even weather.
.
The maneuver I want to teach is important, but it exists within the bigger, unpredictable context.
.
Kata works the same way: the theme guides practice, but real attacks rarely arrive in neat, expected packages.
.
Training within the theme builds the ability to adapt.
.
If we see the theme as rigid, that every move only works in one set way, for one type of attack, then yes, we would be trapped and it would be unrealistic.
.
But when we understand the theme as a guiding principle, it opens rather than closes the door. A technique is never just about the surface movement; it’s an example of a principle in action. The punch isn’t only a punch, the block definitely isn’t only a block.
.
And when we face an attack that doesn’t “fit” a theme, it doesn’t matter, because we’re applying the underlying principle, not clinging to choreography. It gives us structure to train, but freedom to apply.
.
For example, in Pinan Shodan, let’s say the theme is preventing and dealing with potential grabs and controlling after contact. That doesn’t prevent us from using any of the movements differently. How? Because we are looking at movement, not technique. Just because a movement is at, say, head level, doesn’t mean it can’t also be applied at middle or lower levels.
.
Do you see?
.
It’s the shape of the movement, combined with the principle, that allows us to adapt and not be stuck in one place.
.
A central theme is to guide us, not restrict us. Without it, well… it’s just a bundle of techniques strung together. Does that make sense?
.
The takeaway is simple: just like a driving lesson teaches a maneuver while forcing the student to handle the unpredictable, kata trains a principle while preparing you for the chaos of real confrontation.
.
If a drill, or even a driving lesson, has a concept running through it, wouldn’t the same be true for kata which is a blend of the drills already practiced? After all, when learning to read, the alphabet is the guiding theme.
