low/ high sounds on a pipe
this is probably to do with the physics of the sound waves so i thought it was best to put it in science.
At cadets, we use a boatswians call to pipe ceremonial occaisions or announcements ie, the ensign has been raised or lowered, or its time for a break.
this is a picture of one. http://ahoy.tk-jk.net...es/BoatswainsCall.jpg
Because there is no ball or anything inside the bouy, you have to cover your hand over the hole, to make a high sound and don't cover it, for a low sound. However when i do it, its the reverse, it doesn't matter which pipe i use, its the same. but why and how?

There appears to be some useful pictures and guide instructions from around page 7 onwards. Have you already seen it Molly?

If you go to page 12, it says how the raised hand makes a low sound and vice versa, but no mtter which pipe i use, i can't do it that way and noone can do it the way i do.
One of the calls, the carry on should go from low to high, but i have to do the hand movements the other way round, to create the right sound.
So can't anyone explain the physics behind what is happening?
