i learned from a movie i bought at walmart H.S Waterfowl Duck Calling 101. Find you a tape or something with duck sounds on it and just mess around with it till you get close to the sound, then get mad a cuss when you lose it and cant get it back. then throw some stuff, practice some more, and some more, and some more and you get it. Also what helped me a lot was talkin to a guy at the sporting goods place i got my call at. He gave me like a little 10 minute lesson which taught me more than the hour long video did. Just dont get discouraged about it if you cant get it.
