Yea, right now i'm looking for resources that at least attempt to describe and teach posture, hand patterns, etc. I may at some point hire a virtual teacher, but that seems difficult to setup. I imagine they'd need cameras, my hands, body, etc - and it sounds like work. So i'm going to pursue some non-live methods i can find, if any.
There's an app for VR on Oculus Quest [1] that the dev is working on live instructor collaboration as well as set learning pieces. He has upgraded the hand tracking for physical keyboards a few times I am not sure it's current state but this maybe of interest to you guys.
It's just not the same. At one point I moved away from the city where my teacher lived. We tried it over skype, with me changing the camera angle a bunch so he could observe properly, but it was slow, frustrating, and he missed so many things that came to light when I went to visit for an in-person lesson.
Music teachers are cheap to hire. Even 1 hour a week for 6 months would do WONDERS, and not cost much. Plus, your teacher will likely be a student as well, or attempting to supplement their music career. Taking lessons is supporting the arts directly.
