OG, to get the growl to start the bugle just say GRRRRR or URRRRR then go into the bugle notes. It should come from the throat to get that growling/roaring sound. With a mouth call try sayin URRREEEEEeeeee, that should get you a feel of what is required...don't blow to hard. You want to increase air and tongue pressure when your climbing notes..so it should be low to high and then you can end with the same low or growl, if you like.


Keep at and best of luck on your hunt!!!
