Bill, throughout my life I have had an interest in acquiring skills that some people can't do while other people can do quite easily. With some effort, I have managed to gain a lot of these skills, but there are still more (currently trying to learn pen tricks). My question: Which of these things can and can't you do: snap, whistle, finger-whistle (the loud high-pitched one used to call horses), and roll your r's. (no shame here. you are already immensely talented)
can snap just fine, whistling will work but i don't really have any range, probably less than an octave (B to Bb or maybe less, and not reliable at all). finger whistle i wouldn't even know how to attempt. rolling r yes. cannot do the back of the throat roll, as heard in roy orbison's pretty woman
