in your free time explore what kinds of crazy noises you can make up, i think actual singers do stuff like this but try to get real freaky with it and surprise yourself with noises you didn't know you could make
Allow yourself and the people around you the grace to squelch, squeal, and make automobile noises. some days you just gotta meow. others you just gotta seagull.
I learned to do this from a very young age for commercials and theater but I don't do it often bc it can get awkward so only a very select group of ppl have experienced this.
