What changes does the flute film have in rainy days and sunny days?

Relevant, because in the past two days, my flute has also encountered such a problem. The weather changes and the flute membrane is not so tight and suitable. If it is loose, you can put some water on both sides of the flute membrane. , like wiping it on both sides, if it’s tight, just press it gently on the flute film. In order to protect the diaphragm, you can wrap a layer of paper around the hole of the diaphragm and tie it with a rubber band. If you often encounter such problems, you can choose a reed flute membrane. This kind of flute membrane is easy to use and its tightness is relatively better than other types of flute membranes. Having said that, I hope it can be helpful to you.
