Well, see if I can help ya. It would be best if you could here what it should sound like, but, here goes. First of all, there is no perfect sound from any one call, or caller. I've called with many different people, and even with the same call, not one of them sounds exactly alike, so, with that said, don't worry about sounding just perfect. First, I'd say, try to imagine yourself as the rabbit in the claws of death, something has a hold of you, your lungs are very small, so you can't, shouldn't scream looooonnnngg screams, keep them short, add a quiver, such as you're try to escape and screaming at the same time. Scream for about 10 to 15 seconds at a time, remember, your lungs are small, so if you were the rabbit, you'd have to stop to catch your breath. After screaming 10 to 15 seconds, wait and watch and be ready, they could show up very quickly. After a minute or two goes by, nothing shows, do it again, try to very the pitch and volume some each time. Continue to do this for 15 minutes or so. Try to put alot of excitement into your calling, again, that's why I say to picture YOURSELF as being the rabbit in the claws of death. You don't have to wait 2 to 3 minutes between calling, you can vary this time also, can vary the length of time that you stay put, some stay for 30 minutes, I sometimes stay for only 10 minutes. You can use your calling hand to partially cover the end of the call at times to help vary the volume and pitch, and use how hard you are blwoing to vary the volume and pitch. Some callers like starting a set with low volume, they say in case a predator is close, but I always start loud, but I call very open country. Some say the sound would be kinda like a baby crying, which is a pretty good comparison also. If at first, you don't succeed, don't give up, I think that is why more hunters are predator callers, 'cause they expected success right out of the gate. First off all, a coyote has to be near enough to hear the calling, then the calling has to convince him that dinner is served, and last but not least, the coyote has to be in the mood to come and look. I've seen coyotes that could hear a call, simply turn and walk away, so, just becasue they can hear a call, doesn't mean they are going to come on the run, and if they've been called in and shot a time or two, all bets are off. Good Luck!! Sorry for the long post.
