What do people think about the use of vibrato? I mean, I personally prefer a little vibrato, because it gives the tone a certain quality. But I was discussing this with my music teacher the other day and he doesn't really like it and said that I should play the note straight. I can do it both ways, but I prefer vibrato - not a great wide wah wah wha to the note but just a slight oscillation. So I just wondered what others think about vibrato? And what are the best ways of producing a vibrato?
