day 309: miao dao basics

concepts:
  • triangle
  • borrowing
  • percussion point
lessons:
  • miao dao
i should note that i'm going on vacation for several weeks, and so i'm going to miss class for a little time. as a result, there won't be new posts for awhile. i'll be back in early July, so things will resume then. this post will be the last for now.

miao dao

we resumed the miao dao lessons. oddly enough, Viet wasn't here. but we had enough people that we could still partner up for practice.

today was mostly spent on familiarizing ourselves with the weapon and trying some basics. there's a bit of an intimidation factor in learning weapons, particularly ones like the miao dao, which can generate a lot of force off simple movements. this factor is multiplied in the initial stages of learning, when use of the weapon is still clumsy, since minute mistakes are magnified into physically dangerous consequences. as a result, it takes a little time to just get used to the miao dao, particularly in terms of learning how to manipulate its weight and inertia and understand its characteristics in force, direction, and spacing.

Sifu showed us the opening movements of the initial form, and then focused on having us just practice the applications of the movements in pairs. the movements look simple, but they're very precise (simple movements = lots of force, remember?) and require some getting used to.

this was particularly true for today. i had trouble with just about everything we were doing. the movements are all new and so felt unnatural to me. the first application, for example, was most vexing. the idea is to receive an opponent's incoming downward strike without blocking, but instead receiving it so that you use the force of their strike to drive your miao dao down and around to strike in return. essentially, you borrow their energy. it's meant to be a combination deflection and strike, so that you deflect their attack in a safe direction and move yourself into a striking position.

the idea is to receive by forming a triangle between your arms, your miao dao, and the opponent and then borrowing the opponent's energy. i really struggled with this. i think it's going to take some time until i get comfortable with the miao dao and get some intuitive sense of its feel and physical characteristics.

Alex, who stuck around for a little bit, also pointed out that it's important to have an awareness and instinctive feel of the percussion point of the blade. the percussion point is a term from engineering, and it refers to the point where a force vector won't generate a torque or rotation on a body mass but instead produces a lateral translation of the body's location. this is important, because it means the maximum amount of incoming force engages in a reaction with the mass to generate a recoil, so that the reactive force is an inelastic collision rather than an elastic one. an inelastic collision means an efficient transmission of energy, elastic means dissipation and hence inefficient transmission of energy.

for objects like a tennis racquet, the percussion point is often called the "sweet spot" in the center of the racquet head, where the ball won't generate a torque moving the racquet around the player's wrist and hence generate inefficiencies in the player's application of force (and hence dissipate the player's effort), but instead transmit directly into the racquet and generate maximum recoil off the racquet head, thereby maximizing the player's application of force.

for a bladed weapon like the miao dao, the percussion point is somewhere along the blade, usually closer to the handle. if you receive a strike on the percussion point, you maximize the amount of force you can borrow and minimize the amount of effort you have to use. if you don't, you have to expend more effort, wasting your energy.

the thing is, you can't think consciously about the percussion point in the context of actual use. it has to be instinctive and natural. and for that to happen requires an intuitive grasp and comfort level that can only come with time. given my relative lack of exposure to martial arts over my lifetime, i haven't had that time.

which means i have to spend that time now.

so yeah, this is going to take some work.
