BOWING WORLDS20

The thumb acts as a hinge and supports bow-motion adjustments.

Task Detail: THUMB HINGE

Default 3

A hinge is a flexible joining piece that allows the rotation and pivoting of a part, a door, for example.

The thumb’s range of motion includes the action of bending just like a door hinge. 

The last segment of the thumb functions as a hinge, by flexing and extending, as the bow is drawn across the strings.

Change of bow-direction motions requires the ability to perform flexible bow-hand rotation and angle adjustment so that you can change smoothly from down-bow to up-bow.

When the thumb hinge is not free to move, it causes the thumb joints to lock. The unfortunate result will be a chain reaction of locking, continuing to the wrist and the bow-arm. In addition, the other fingers on your bow-hand will become rigid and have extremely limited flexibility. You must keep the thumb flexible while securing a strong, controlled, loose, tactile sense.

The thumb hinge begins in a curved position and then straightens slightly while performing the motions of the down-bow.  The thumb hinge returns to the original position when changing to the up-bow.

Keep the thumb hinge loose, flexible, anchored and springy.
