yeah gotta agree. Don't really think theres really any black magic. You sink it it sharpens, raise it flattens, tape it the note flattens, open it gets harder, pinch it gets easier, wet it sharpens.. I guess its knowledge as to what do when. And training your ear to whats flat and whats sharp.. Our band wants people to learn certain things and teams people up with the ones who know stuff. Last year I was made drone guy. And loved it. This year Im learning chanters and I've been teamed up with a "mentor" He goes off to tune, I go with him. A practice, trial and error. And Im starting to get it.
