I'll try to record a video. It's better to hear.David Cooper wrote: ↑Fri Mar 29, 2024 6:59 pm The photo's there, so that works. I'd love to hear more detail about how it covers the 12 chromatic notes, and about the cool slides. It sounds interesting, and especially the elliptic aspects.
In short... Do you have an Irish flute? How are things going with half-covers? The answer is no. We have bad sound!
- On elliptical holes, we maintain the shape of the hole by reducing it with our finger. Like a recorder's bottom holes
- On the Irish flute we get a thin gap - but the air doesn’t like that! This is a thumb hole recorder effect.
Therefore, on my Irish flute in D, I want to make the lower hole E elliptical as well! Like the top one. It let me the better control on D# and the 2-nd octave (like recorder's thumb hole), when it's necessary.
