I'm curious, for those of you that have several years of experience with the trumpet (I'm a newbie), how do you break up your yelps and add inflection, so you aren't a monotone caller? Or can you? With pots, diaphragms and boxes, which I am fairly proficient with, I can add hiccups and a good deal of inflection and excitement into my calling. I know some will say Practice but is there some tidbits of instruction that will help?
