Vibrato without Violin V.01

Vibrato practice without a violin.
Hold your phone in the violin left-hand position and move it gently toward and away from your body, about 2 cm: the real violin sound (A=442Hz) rises and falls, and that is your vibrato. (Toward your body = higher pitch.)
Practice the small movements of arm, wrist and fingers anywhere - on the subway, in the car, during a break.
Compare with the sample sound, fit your vibrato width to the sample, or adjust the range (1-2 cm).
