7 Concert Violinists Teach Vibrato (Tonebase Violin) 

The difference in views is really interesting here!

We've got many threads on Vibrato, many discussions & videos on the forum, but I still get frustrated with physical problems. 

I'm getting a little better with wrist vibrato, but I would still like to be able to do arm vibrato. 

My problem is no matter how relaxed I get my arm, some muscles (or tendons?) are used that attach to my upper arm/shoulder area that aggravate my bursitis & arthritis (yeah, I got the itis 🥴).  Jeez, it was bad enough when I 1st started playing I'd rest my elbow on a pillow to play - so I could avoid steroid injections! 

Okay, even though I've paid more attention to my overall arm, hand & finger warm up lately - think I'm going to have to start paying MUCH more attention to carefully working my left shoulder/upper arm to free it up more.  Like many other things associated with my playing the Violin/Viola, I have no clue why I've managed to gloss over this... maybe because I thought all arm vibrato was isolated in the forearm.  Not sure if it's tendon or muscle tugging, but once I laid my right hand where my upper arm meets my shoulder, completely relaxed, I could feel what was happening - it's NOT my arm moving at the shoulder, if that makes any sense. 

...this is going to take me awhile.

Just another good reason to try to learn to play these bowed string instruments when younger (if at all possible)!
