Open Reeds?
If your reeds are too open – maybe you’re tying them too short.
Always tie the reeds as long as they want to – at the point where they close nicely. But not shorter than that.
If that doesn’t help – try a narrower shape. Especially narrower in the lower part of the reed, near the staple & String.
Opening depends more on shape and tying than it does on gouging.

Know that annoying legato D-G? The one that often cracks?
Well, open your lower jaw as you hit the low G. It will not crack!
And another little trick: lift the first finger of the left hand while you play D, then press it only when you play G.
=========================
Never Cut your reed if…
1. The reed is too resistant
2. The reed is too open
3. The flow of vibrations is not smooth
