I'm pioneering the field of psychologically humorous rap music. So you pray on chocolate and wish life were dull. I think you get the concept. Actually, all kinds of folks really go for the rap. I can tell when an audience is applauding from relief.
People enjoy and are more receptive to a serious message when it's gift wrapped with humor.
The rap also works for other reasons. But after awhile, almost all appreciate that I'm having a grand time just letting it hang out. I'm not particularly worried about looking and sounding ridiculous. And, in the end, I can even poke good-natured fun at my singing. If I'm not taking myself soooo serious, maybe audience members, too, can be a little less hard on themselves.
