C. Fingertip + Hand + Forearm The forearm follows the fingertip + hand combination. Notice how the thumb and radius bone are now a part of the motion. (The radius bone is the left bone in the forearm when the left palm faces you.) Warm up: Shake a matchbox, noticing how the motions of the fingertip, hand, and forearm combine. Using the example above, apply the combination of fingertip + hand + forearm to the vibrato motion. Quarter= 60 Play 1, 2, 3, 4, and 6 cycles per heat D. Fingertip+ Hand+ Forearm+ Upper arm The vibrato motion that includes the upper arm is the slowest. The left arm should always feel free and loose, as if hanging. Weight release of the collarbone and shoulder blade are essential, as is release in the elbow. Returning to music example 2 above, apply the fingertip + hand + forearm + upper arm com bination to the vibrato motion. Quarter= 60 Play 1, 2, 3, 4, and 6 cycles per beat Ill. CHANGING VIBRATO SPEED Apply the following exercise to all strings and positions. Play two vibrato cycles per beat at Quarter= 120-192. A. On each finger, play a quarter note (two vibrato cycles) and stop at the beginning of beat two. Be sure to stay exactly with the metronome.
