The Thumb acts as the Bow-Hand’s
Anchor, Spring and Hinge.
THUMB BOW-LOCATION
A comfortable bow-hand set-up begins with learning the exact location the Tip of the Thumb makes with the bow. The contact location of the Tip of the Thumb centers your bow-hand. From this central location, your hand will be set-up correctly and ready to perform varied tasks in the bow factory.
Often, students notice the curve in the frog and assume that the thumb is placed in this slot. The thumb is not placed in this location. This error locks the wrist and inhibits natural bowing motions, resulting in rigid and harsh sounding changes of bow direction.
Hi, Scroll! Tell us, please: Why does the bow’s frog have a curve?
Well, the reason that the curve in the frog exists has to do with the origins and then the evolution of the bow’s functions.
Before a screw mechanism was invented and became standard, the hair was affixed to a curved piece of metal, or carved wood that the player then wrapped around their thumb.
The Bow Hair was pulled into tension by tucking the thumb into the palm. This motion placed the angle of the hand towards the strings and allowed the arm’s weight to be placed into the strings simply by turning the hand.
V made me promise to mention that this, turning of the hand (thumb curved towards the palm) is the most beneficial leverage concept to hone in your bow-hand set-up.
Now, let’s learn the specific Tip of the Thumb Contact-Point References.
