Invented by a professional violinist and teacher, the Virtuoso Wrist Practice Aid is the first and only left-hand wrist aid made specifically for all string instrument players. It's the ultimate teaching and practice tool, designed to help beginning string students learn and practice proper left-hand wrist position. 

Custom straps adjust around the palm above the thumb, and around the forearm near the wrist. It enables the student player to learn correct “straight wrist” left-hand position, as improper “wrist bent backwards” left-hand position prevents the fingers from efficiently reaching the fingerboard. It also enables the student to understand basic shifting from 1st to 3rd position, as it helps the student keep the wrist and forearm “moving as a unit” during this more complex task.

The Virtuoso Wrist Practice Aid is also a great vibrato teaching tool because it restricts a student from moving the wrist in a funny motion just enough, but has the built-in flexibility to allow the student to learn the motion of rocking the finger back and forth. 

Fits most players using 4/4-1/2 & 1/4-1/16 size instruments.
