I have just recently started trying to overblow. I started off by taking off the top cover plate and manually stalling the blow reed, then trying to activate the draw reed. I noticed that every time i overblew the note it after i was done my draw reed would be stalled, not reacting to a normal draw. The same held true after replacing the cover plates that every time i eaked out an overblow the draw reed would then stall. Is this normal? am i damaging my harp? Is it a problem with my technique? Any help is greatly appreciated.
Dont laugh, but i am obviosly no pro at overblowing and it did not occur to me that overblowing may be easier using the lip purse method opposed to the tongue block. After practicing with lip pursing not only is it 100 fold easier, but no stalled reeds!
technique is more important than setup. you can blow stock harps. It may be necessary to set up BOTH valves on the required hole. higher key harps overblow easier. Some brands are more difficult than others to blow. A badly set up reed is a recipe for breakage. Trust me...
Personally, I don't have to wallet to keep practicing overblowing. I'm resigned to following the old masters who rarely over blow. For now.
Curious, how often and how many reeds have you broken? ive been overblowing since my last post relatively regularly (mostly on the 6 hole for cross harp) and i havent had any problem with breaking reed.
i dont know if i will be able to offer much assistance because its kind of a dont think just do thing for me, but i do know when i overblow the tip of my tongue is pretty much at the roof of my mouth and is crunched to direct the air in a certain way i cant describe and even know. If you got to the 8 hole and blow bend the note till it doesnt sound, thats that tounge position i use when overblowing. Then its just about putting in the right amount of air.
Overblowing should be no more stressful on a reed than regular playing.
If you are breaking reeds frequently, there is only one reason - you are blowing too hard. Like bends, overblows are not forced from blowing or drawing harder - they are achieved by subtle changes in resonance and angle of airflow caused changing the shape of your mouth.
Gapping helps a great deal, but it's possible to OB stock harps. German made harmonicas are much better for OBing than Japanese or Chinese made ones (it's to do with the reed dimensions)
