Vibrato without Cello V.01

Vibrato practice without a cello.
Hold your phone in the cello left-hand position and tilt it like a wrist rotation: the real cello sound (A=442Hz) rises and falls, and that is your vibrato.
Practice the wrist motion anywhere - on the subway, in the car, during a break.
Compare with the sample sound, or fit your vibrato width to the sample.

• Smartphones only. Open in Chrome (Safari on iPhone) and allow motion sensors. Sensors or sound may not work inside the KakaoTalk or Naver in-app browsers.
