upside-down ramp on whistle blades?

Have any whistle makers tried building a whistle with the ramp on the bottom of the blade instead of the top? Would this have any effect on the sound/playability of the whistle? I realize it would be harder to make in most cases.

I think it would force far too much air into the whistle, rather than dividing the inside/outside air stream.

Just as an interesting continuation on the same line of thought, the blade of my Alba Q1 looks like this:

That’s right, the crazy thing doesn’t really have a blade exactly, just a chunk of blue metal with a square end where the blade would be.

The odd thing is this is an oustanding whistle, with a moderately soft, very traditional tone, and is wonderfully responsive through two octaves.

Go figure.

It depends on how the airstream intersects with the ramp.

The complexities of the duct, window and blade interact with each other. One item standing alone cannot be perceived as good or bad.

Very true-- even tiny variations in measurements in this region of a whistle can make HUGE differences in sound.

Regarding blunt blades-- my Overton A has a blade with a nearly vertical edge, with little ramp to speak of, and it plays like a champ. On occasion while voicing a whistle, I’ve tried playing it a bit before filing the ramp and it sounds surprisingly OK.

There are whistles made like that but the end is closed and it has no tone holes. Just plays one note so you need several to play a tune. The notes are more steady and very consistant and you would not be able to raise or lower a note by speeding the air flow or slowing it. Works the same way a pan flute does but you don’t have to shape your mouth to play it.

A good many “regional” bamboo whistles are constructed like this:

The plug need not be slanted, as it’s played in a vertical position, which gives it a de facto slant at the top.

Actually that is a good design which I have used with pretty nice results.

My borrowed computer isn’t letting me input pictures, but I can describe it in an email message if you want.

Native American flutes have that type of ramp, and there are some oriental bamboo ones with the same thing.
