For the experienced callers in the group, two quick questions on mouth calling. First, on grunts: are you building up pressure to a high note quickly, then dropping it all of a sudden to end it (think almost a bugle packed into a half second) or are you starting on a high note immediately and then dropping it? I've been listening to Corey and it sounds like he does the former- I can almost hear multiple notes building very very quickly in each grunt. The latter is much easier since all you need to do is blast some air and then drop the pressure... but is sounds one dimensional when I listen to Corey make the grunts. Second, I can bugle okay, but my mews are off. I would think a cow call would be easier than a bugle, but it isn't for me. I seem to be off key or something. I've tried a few different calls, varied my pressure, tongue position, etc but I can't seem to get the mews to sound buttery and smooth. Mine sound kind of shrill and annoying, like I'm tone deaf. Any ideas?
