Well, no...it's true that I have not played one of your flutes But your design is quite interesting. However, it's not quite apples to apples, if you know what I mean. The pictured flutes (the bansuri and Erik the Flutemaker's) versions appear to have the more typical round cut, and presumably their undercut is conventional (in degree) but that's impossible to tell. Your pictured flute obviously has some unusual modifications that will have a noticeable effect on it's response. Like the addition of Adler wings to a lip plate (for example).Sedi wrote: ↑Tue Apr 13, 2021 8:42 am You haven't played one of mine then. Obviously, since so far, nobody has, except me. However mine only look round. I drill them at an angle and make the edge very sharp - it's more modeled after a quena, just sideways. Works great. And I did compare them to at least 3 other well known makers. Unfortunately, there's not too many shops around in Germany that actually carry "Irish" flutes. And I can't buy a whole lot, just to compare.
The big question for me is not whether a round hole will give you a decent tone, or whether you can make a playable Irish flute, but rather whether the player's ability to achieve more nuanced execution of traditional ornaments is at all reduced as a result of the shape? Again why do so many of the top modern makers (and historical makers) seem to favor an ellipse over a round shape? And I would genuinely welcome other viewpoints apart from my own. Any other makers care to chime in? And again, we are speaking of ITM oriented playing as per the OP.
