I always assumed I did not have a vibrato. But I know people have control over it, and can choose to sing with or without vibrato? Are there techniques to learn to control it? I just realized yesterday that when I goof around and sing like a lounge singer, I have a vibrato!
I have been singing my own originals for years, and since I am not yet famous, I figure it has a lot to do with my voice, although for now I would like to know if others have taught themselves to use vibrato.
