Practice
I do not know what is causing the mistake
The passage contains too many simultaneous variables to diagnose as a whole.
This governed route starts from what you can observe. It is source material and routing help, not a replacement for the current teacher seeing the player.
What you can observe
- diagnose violin problem
- practice troubleshooting
- isolate hands
First bounded action
Run three separate tests: left hand silently, bow on open strings, then rhythm on one pitch.
How to check it
One isolated test reproduces the failure while the others remain stable.
Stop condition
Stop once the failing subsystem is identified; route that specific problem next.
What this route cannot tell you
This route can help name an observable violin problem and choose a bounded test. It does not override the learner's current teacher or diagnose an individual player from a webpage.
What Ben's clips show
No reviewed clip is attached to this route yet. The route language still comes from BenChanViolin's governed technique router.
