Yes and no.
Yang Cheng Fu style TCC as I have become familiar with it is a large framed form. Wu style as I study it is a small framed (and square to boot) form.
I don't know if you're familiar with frame sizing in TCC, but the way I understand it there are three sizes of "frame". Large, medium and small. These will sometimes correlate to how I described "throw ranges" but don't necessarily have to.
No, it doesn't always make sense.
I don't want to make a big deal out of the idea of a "throw" range, it's not technically important. It's how I and most of my former schoolmates referred to the distance between us and our opponents. I imagine it had a bit of tounge in cheek with it, though I have seen our other resident Wu stylist, Polaris, refer to them this way as well in some of his posts, so it's probably a pretty widely used term in North American Wu style at least.
But don't worry about it, it's not really that important.
A throw is like anything else, the more room you have to work with, the bigger the lever you can apply to the motion, the farther you can move, or in our case throw, something or someone. As the distance between you and your throwable object decreases you have increasingly shorter ranges of motion and shorter levers you can effectively apply to it, so you get a shorter throw. The force of the throw may actually increase, in that while he won't go as far he will likely hit the ground with much greater force.
If you would prefer we could simply call it "range of combat" instead of "throw range". It means the same thing.
The importance of frame size comes into play when you speak of "range of combat", though opinions vary on that as well. How far away are you? If your opponent is a good distance from you, then you can comfortably set up in large frame and apply the types of moves you would use against an opponent that far away from you. If he gets a bit closer and steps into medium range, or you step into his, then you would likely wish to apply a medium frame to your postures to meet his offense. Same for if you get up in each others faces, then you will wish to use a small frame with much smaller circles of movement to counter his offense.
Does this make sense?
The theories differ. You can, of course, use small frame when you're farther away, large frame when you're closer, it's all a matter of application. So it's a general theory, not a rule written in stone.
I have heard differing opinions on the effectiveness of these frame sizes and how they should be trained. The Wu folks seem to feel that large frame is much more difficult to master. The Yang Cheng Fu guys seem to think the opposite.
Some Wu stylists feel that only the square form of Wu Kung Yi with it's small frame size, small circles and small jins, is worth a darn, but then you find out that the Wu families "fast" form is a large framed round form that is nearly identical to old Yang forms with all the fajing, leaps and stamping intact, and they refer to that as their "fighting" form sometimes. There is also, I have found out recently, a medium frame fighting set taught at the Beijing school of the Wu style.
Different Yang family members seem to prefer different frame sizes as well. Yang Jian Hou was said to be the master of the medium frame in his time. He is Yang Cheng Fu's father, who is the recognized master of large frame Yang style.
Wu Chuan Yau trained originally in the large circles with Yang Ban Hou, then learned the small circles from Yang Lu Chan and decided to train his students only in the small circles he thought they were that much more effective.
Yet his son, Wu Chien Chuan, opened the first academy of TCC that taught the public TCC with Yang Shou Hou and Yang Cheng Fu, teaching all the frame sizes together in one place.
So it goes.
I have found the differences in applying the theories of the differing frame sizes to be profound, however the same theories apply, only thier actual application differs.
You can find all kinds of interesting stuff about these things in many different locations on the internet, even right here on this forum in past threads where we've waxed poetic about it and even argued volubly in good clean fun over it, and in the books of the Masters.
Dr. Yang Jwing-Ming has quite a bit to say about these things in his books, for one. There are others with just as much good info on these things as well.
I have learned several large frame forms and a couple of different small frame forms fairly well. I've been holding out and hoping for a chance to train in the medium frame of TCC, but haven't yet met a master with the skill.
Let's let this thread move on, we've bogged down in the frame size issue a few times in the past without much progress made in convincing anyone of anything about them they don't allready feel to be accurate.
There are those, maybe rightly, who feel I'm a bit too obsessed with frame and circle size.
But it does keep me off the streets and give me something better than wine, women and song to think about...
Well, I guess THAT'S not true, but at least it keeps my mind occupied on something other than less than prurient pursuits.
