The air you use to get the correct sound from the call is the same air you would use to fog your glasses, or the air a quarter back says hut hut with. As already been stated, it needs to come from your diaphram. I would suggest spending the money on a Buck Gardner instructional cd. He makes it very easy to understand. I sucked for years until I got Buck's tape and it changed evrything almost overnight. After learning duck calling from his tape, it made learning a short reed goose call a piece of cake!

Good Luck!!!
