I think what you were trying to say was "...beautifully expressive vibrato...", Jack

I think you mean tremolo. There is a "slight" difference in that vibrato is a modulation of amplitude, not pitch. Call me a pedant, I deserve it.
Edit.
Er... I just looked the two terms up and it seems I am wrong, or at least... not correct. The definitions coming up are varied but I think it is fair to say that this could be a new topic. Look out for a new post entitled; "Are Tremolo and Vibrato not the same thing then?"
