Practice choking the reeds isolated and at different pressure levels.
A good excercise for choking is bending down the lower blow notes while trying to stop the draw reed producing sound.
Once the blowreed reaches the point where it would normaly choke, you can keep it sounding by increasing the pressure. This will most likely also cause the drawreed to respond first.
Working on not letting the drawreed sound will give you a good control of the two seperate parts of the overblow.

Good to hear from you, I play your CD to all my students so that they know there is more that you can do with the harp.
I met you a few years ago in Trossingen.Great site,really valuable information and great playing. Mick.
For the overdraws. If you isoltae the blowreed and play the overblow that way, you will notice that you don't really need a lot of force when playing the overdraw. Again it comes down to setting up the reed properly. If the drawreed chokes it should loose almost no air at all.
- I also have problems with over draws. I can do over blows with a relax toungue but with over draws it is such a high note. How should i do that with my throat? TENSE ? I c an get them to sound some times with my tounge?
