I remember Adam Gussow doing a you-tube series and in one of the early ones he works on those tough-for-some draw notes. kudzurunner That's Adam's You-tube channel.
Everything is very easy thus far, except...
When I try to draw on holes 2 and 3, I get this very dull sound, almost as if the air is partially blocked or the reeds aren't vibrating.
I tried the same thing on a few other harps I had laying around and got the same result.
This struck me as odd because all the other holes worked so easily. Why should those two be a problem?
