Oh I agree. I know someone who went from classically trained vocalist in musical theater in college, to national musical theater touring star, to Broadway star, to one of the top agents for TV, Hollywood, and Broadway. If I could tell you who he reps, you'd be amazed.

He has always had super professional performing chops. He told me once that the biggest weakness singing performers have now, as recording artists or in musical theater, is most of them have never been trained classically as vocalists with a voice teacher so they cannot hold notes out for any decent length of time in tune. They never learned to breath correctly while singing or using their ears, nose, throat, respiratory system, and diaphragm correctly. Most of the top performers have been well-trained BTW.

So they learned to compensate with vocal ornamentation so they don't have to. I've seen that SO many times and as a musician, it always irks me when performers overdo vocal ornamentation. Same feeling I get when I hear Kenny G on saxophone. Ugghh...
