I have Shaw, Overton & Howard Low Ds.

I do the reverse of Bob Bolton's suggestion, which involves dropping the elbows to the sides of your ribcage.

I discovered the position from the 'Flautist' position. Hold the whistle out to the right, with your hands on the outside of the whistle as if playing a 'Flauto Traverso' (modern flute or fife).

I mention this because in the Movie "The Great Escape" the fife is shown being played with the right hand reversed, a position I am not familiar with.

Place your finger tips over the holes, then rotate the whistle into the normal playing position out front and down. This will cause the hands to rotate into a position with the elbows tucked in. The side part of the pads of some fingers come into play, and the fingers become curved, compensating for the differences in distance between the fingers. I find it a very relaxed position.

I had a picture a friend took somewhere, but I can't find it.
