I’ve seen a bunch of tutorials for this, but I just can’t do it.
My problem is that I just don’t understand how it works, so I can’t fix my mistakes.
I assume that fingers act as rigid stabilisers to prevent <something> from deforming with increased pressure, but what that something is, I don’t know.
I also don’t get how the air stream works, or the basis for the whistle.
In normal whistling you aim an air stream downwards from your palate, *across* the hole between your lips – like blowing across a coke bottle, but from the inside.
Where does the air go for the two-finger version? Is it the same, it up above the top teeth (as for a *sshhh*), or what?
What am I actually trying to achieve? If I knew that, I think the instructions I’ve seen would make more sense.
In: Physics
Can you whistle without your fingers?
Whistling is about two to three things.
Aperture size- this is how big of a “hole” you make
Air velocity – how fast the air is moving.
Direction of airflow – how the air moves through the aperture
These three things are what you need to adjust.
Typically the louder you want to whistle the more air speed you need.
Consequently the faster the air is moving, the smaller the aperture you want to use.
