The Thumb Stop can help improve Birls, Taorluaths, B strikes and grace notes. By keeping the thumb of your right hand directly behind the middle finger, you will train your thumb to stay in position. Once the thumb is trained to stay in place, the Thumb Stop can be removed. It can be used on both Polypenco practice and pipe chanters.
Caution: It is highly recommend that the Thumb Stops be used only on Polypenco (plastic) pipe and practice chanters, as they could damage wood chanters.
