Hey Andrew,
I have a question regarding the discussion on vibrato in the slides lesson. I am a violinist just beginning to learn the uke (thank you so much for your lessons). For me the natural way to do a vibrato is a more side to side motion (finger stays stationary on a single pivot point and moves back and forth over the pivot point not moving the string). You have said specifically to NOT do it this way with uke but instead to use an up and down motion (which to me feels more like moving the string up and down as opposed to pivoting on one point). Right now this motion is new and more difficult that what my many years of violin has in my muscle memory. My question is, am I interpreting this correctly? should I be trying to move the string up and down? Also, is there ever a time when the vibrato I am more use to from violin is appropriate?
