I'm a newbie to the harp & found draw2 a bit tricky, I hadn't realised that I was drawing air in through my nose which hindered me. I just placed my daughters swimming nose blocker(is that the right word) on & found the right strength almost immediately, feel free to scoff(go on) but, hey it worked for me.
By the way, NO I do not wear it all the time whilst playing
, took it off after an hour as I'd "got" the technique.
I think a great deal of harp technique is hard to grasp, bit like learning to click your fingers, how do you explain that in words, tricky, you just suddenly "get it".
Hope this helps any newbies(like me) & if your a pro then please post if all the above is not the ideal way, I'm here to learn
