REVIEW: Cello Bow Force - Bow Training Aid from Shar Violin Shop (originally posted on Instagram on June 13, 2019)

I purchased this device specifically for the purpose of reviewing it and have used it for approximately one month. This was not a sponsored review, and the Cello Bow Force was not provided to me by Shar Violin Shop.

PROS: This device does what they say it does: helps the player keep his/her bow straight. It is easy to put on and remove. I know many teachers are against such devices, but I believe that if used in moderation and stimulating critical thinking in the student, the Cello Bow Force is a great tool. The key is to have the student note the results of the better bow arm usage and the narrower rosin spot on the string. 

CONS: The $34.95 price ticket. The Cello Bow Force is a simple concept made out of cheap materials. I believe $15 dollars would be a great price. As far as the cons for bow technique, there are a few. This device doesn't allow the player to go all the way to the frog (because the arch is too tall and wide) or the tip (because on the bow change the tip goes through the loop). Any kind of retakes are bound to get the hair stuck on the arch. This device works best for small, on-the-string strokes. My baroque bow was a total fail with Cello Bow Force. 

CONCLUSION: This is a great concept and I would recommend it for a teacher to have in his/her arsenal. It should be used specifically to show the student how the bow arm and bow placement change for the better. The rest is up to the student to work out with a mirror. The build and materials don't warrant a $35 price ticket. $15 would be the best price in my opinion. 

I hope this review helps teachers of beginners and intermediate students.
