Bob,
This a great question to explore, and I will take a stab at it. When describing an Anyo, step by step, the actual physical movement could be described and/or the applications of each movement could be discussed.
For example the first three moves of Anyo Isa are right foot forward, twisting the body to the left, right hand across body to the left, open palm in a blocking motion, left hand comes up over the top of the right hand continuing left, palm open, in a checking motion, simultaneously the right hand retracts to the left dropping down in a circular motion continuing forward in a striking motion, palm open , fist or finger jab.
(whew-get all that? hard to describe in words!)
This also commonly know as "Brush-Grab-Strike" or "Decadena" or "Block-Check-Strike"
Applications might be: Blocking opponents right hand strike on inside with your right hand, then blocking your opponents left hand strike on the outside, then pulling your opponents left hand to your left ribs, stepping to the right and twisting your body left (zoning out to the right 45 degrees) then striking low to the ribs or striking high over your opponents left arm keeping contact with said arm in a shearing manner, hitting the head-neck etc and then an arm-bar is right there.
However, typically, there are infinite applications to any set of motions. Perhaps improved motion descriptions. Maybe some of the other readers here can add more applications and/or describe the next set of motions, and we can keep this going on a continuous basis and complete the form?
What we have here is a study of the "ART" and then applications of the "MARTIAL".
Looking forward to some brainstorming here and input.
