I think I have been accidentally choking myself trying to bend. I flex the soft pallet to make bends on 2,3,4 and 6. It never sounds right and I get a bunch of mucus in my throat causing me to choke. Also I can hear extremely high pitched squeals from the harmonica if I bend too hard. (Fast vibration of one of the reeds, It sounds like a 10 blow on a C but it is a 2,3,or 4) Is this a bad habit I need to stop or is it a legitimate technique some people use? Also I don't tongue block I just make a small hole and that has worked fine for me so far.
Aceal, do you mean you make a small hole with your tongue, the U method? This would cause a sucking effect when drawing back the tongue. The pucker method is to narrow the lips to encircle one hole then draw back the tongue. You are developing a bad habit to get the choking and mucus complaint. Bending is simply ( ???) changing the shape of the cavity in the mouth. You may be OK without tongue blocking at present but you should develop it as it has many uses for later on.
Jon Gindick has a good technique for bending. He uses Kee and koo sounds articulations. Imagine if you can the Kee is going into the head and Koo is hitting the back of the throat. I started off like this and it worked for me. One thing you shouldn't do is drop your chin.
