Bowstopper

The perfect tool to ensure proper bow distribution! For students of all ages. Enables students to learn by feel, not by sight - so they can keep their focus on the instrument itself.The Bowstopper works simply and precisely. Clamp it towards the top of the bow to master upper bow technique, and clamp it towards the frog to isolate the bottom. Use it on the middle of the bow to master such techniques as detache. It's just as easy as that!
