How to Do rolling vibrato on the erhu
In this video, we learn how to do rolling vibrato on the erhu. Vibrato is a series of deliberate and controlled finger and hand movements. It is not convulsing or vibrating your hand to create the desired effect. First, you will need to learn finger movement. You will want to roll down and roll up as one nod once you are comfortable. Start with 1 nod per beat, then progress to doing 3 nods per beat as you become more familiar with the instrument. Next, you will need to learn bowing by setting the metronome at 60bpm. Count the number of nods in your head as you bow. Do the same as you did before, starting off slow then going to more nods per beat. Once you have more practice with this, you will be better at playing it in the future.
