To be honest with you the calls can sit differently in anyones mouth. It all has to do with the size and shape of your mouth. You just have to put it in your mouth and get comfortable with it because it wont feel right at first. Then just put your tounge against the read and exhale. It may take time. I know a lot of people that it took them a while to even make a peep but once you get it everything gets easier. It didn't take me long to start to be able to do it though. It just takes time and practice. You can also order tapes or videos of calling tips and techniques to teach you how it is supposed to sound and how to do it. Good luck.
