Lesson IX. The "Wiper" - A Bow Grip Exercise
This is a simple exercise you can do away from the cello to improve your bow hold and in turn your sound.
Notes about the video:
"As with all bow exercises make sure to watch the thumb on your bow hand. It should be relaxed and flexible through the first knucle of your thumb. Also be careful of your bow--that bow tip is very delicate so be sure you have a clear area before you start "wiping."
