I don't count as "knowledgeable" here, but in case helpful: some drones
have "follow me" technology.  I.e. their firmware contains
object-tracking algorithms optimised for locking-on to, and then
following, a selected person.  Earlier drones used a GPS tether.

I realise that drones aren't ideal if your friend is filming her lessons
indoors!  But it's a market segment that has seen a lot of investment in
tracking people with cameras to achieve satisfying cinematography.  And
some drones might be viable indoors, perhaps?  Especially in a large
room such as a performance venue, if available.

For non-aerial solutions, maybe the following would be a starting point?

Good luck to your friend!
