Task Detail: THUMB SPRING
The thumb acts as a spring mechanism and supports bow motions.
Think for a moment about shock absorbers that are used as springs by the wheels on a school bus. Without these shock absorbers, strong bumps on the road would make it difficult to remain seated.
Combining the thumb anchor task, along with the thumb spring feel, makes thumb functions more efficient. Perfecting a loose and springy, but firmly anchored bow-hand thumb is crucial to bow mastery.
The thumb, acting as a spring, helps to absorb and re-direct weight that is placed into motion while bowing.
Springs support shifts in weight caused by motion.
The motions of the bow, combined with the ever-changing resistance of the strings, require a successful thumb spring action. The thumb is the main part of the shock absorbing task of the bow-hand.
As the bow is placed on the string, there is an immediate combination of energy. The weight of the bow, bow-arm and bow- hand is counter weighted by the resistance of the strings.
The Thumb Functions as a Bow-Hand Spring.
When the thumb is located correctly and set-up to feel springy, all bow motions are much smoother and tons easier to perform!
