You won't need form if you just train drills. Your drills may come from your forms but it doesn't have to be. After you have leaned a form, you take it apart, understand it, and then put it back together any way you want as long as it makes sense to you. The best lesson that I have learned in my life is one day my teacher told me that, "Form was designed for teaching and leaning only. It was not designed for training."
You use "partner drill" to develop your skill. You will learn your
- body alignment,
- power generation,
- footwork,
- ...
at this stage.
you then train "solo drill" at home when partner is not available. Since you have already developed your skill, you just use your solo drill to "polish" some minor detail that you may not pay enough attention when you train with partner.
Since your "solo drill" is just your "partner drill without partner", when you have learned the "partner drills", you will get "solo drills" by default. If you link your "solo drills" in a sequence, you will have your form. This form that you have created will truly belong to you.
I had created the following form many years ago. Do I train it? No. Do I ask my students to train it, No. It just serves as a text book, no more and no less. The first 13 moves are the 13 postures. Since the order of those postures are not important, there exist no value to train those 13 moves in sequence. The rest of 24 moves has many combos in it. It makes sense to train
- combo A as move 1, move 2,
- combo B as move 3, move 4, and move 5.
Since combo A and combo B has no logic connection, to train combo A and combo B together as move 1, move 2, move 3, move 4, move 5 is not necessary.
