Using the Bridle to open or close the mouth aperture
Keeping the mouth in correct adjustment is the one thing you will probably need to do more than anything and the copper Bridle is there to control adjustment of the reed mouth. I use two wraps of wire whereas the more common Bridle is made up of a single wide strip, or ‘collar’, of copper of anything from 3 – 5mm in width. Collar or wire Bridle it really does not matter as long as it performs its intended function, and its sole purpose is to control the mouth aperture. I personally find the wire Bridle easier and less risky to attach and manipulate and so this is my preference. Always exercise extreme caution when making any kind of adjustments to your reed, splitting the reed is easy and very costly.
