The PinkyHold works with all standard fractional and full-size violin and viola bows, except for full-size Glasser Brooklyn Classic and Bronx bows, which are too thick.
Your little finger can have a tremendous impact on your technique and your tone production. It is light, easy to put on and off, and can help children keep their pinkies curved. The purpose is not only to curve the pinky but to give it its due responsibility in balancing the bow hold between all five fingers. Teachers and parents will no longer need to remind young players to curve their fingers when appropriately used.
BowTrainer is the world-first, ground-breaking device that helps students produce high-quality sound efficiently and accurately by developing the contact point, or straight bow, in string playing.
