Now if only that would have an Irish flute or Irish Low D whistle hole layout it would be perfect for me.
We’re so similar in this. I had a combination of wrist and hand pain, with a touch of shoulder pain thrown in for fun, that ended my transverse Irish flute days.
But luckily anything vertical, like bagpipe chanters and whistles, are fine.
There is/was a maker in France (as I recall) making “Irish Kenas” out of aluminium. It ought to have been perfect for me, I got my hands on one, and unfortunately the Kena voicing wasn’t optimal IMHO, probably something to do with the cut of the notch.
Getting the “cut” of the Kena notch just right is so tricky! I played through piles of Kenas until I found one with super easy high notes. Even when out of practice I could pick it up and play up to the highest note effortlessly. I never found another Kena that played that well.
My Quenacho wasn’t as good as that amazing Kena, but it was pretty good, So that was my model for my attempts and my own PVC “Irish Kena”. I made a few of them and never got the notch quite right.
Interestingly, North American Native flutes originally had no notch, but were simple open tubes quite like the Kaval.
I’ve told the story of walking around in the reconstructed Miwok village in Yosemite valley, and finding several Miwok flutes for sale in the gift shop afterwards. Picking one up, I saw it was like Kaval, and began playing it.
A Native American guy ran up and said “you’re the only white guy who has ever been able to play that!” Turned out he was the maker.
I explained that I played Bulgarian Kaval, that it was similar. He’d never heard of Kavals.
Anyhow this led to more experiments with PVC flutes, and I made a pretty good Kaval with a Native American hole layout.
