Question for the advanced students (RCM 8+)

Or teachers who've taught advanced students. What do you expect from your lessons to entail other than just notes, finger numbers, and rhythm (basic stuff)? I'm sure that once you've reached this level, it's more focused on musicality. But the possibilities seems so broad.

I'm coming from the r/pianoteachers but want to gain the perspective from those still learning. I graduated all of RCM and finished my bachelors for classical piano but have very little experience teaching advanced students. I've taught intermediate and below but that is my only reference. And honestly, I don't remember how my own lessons went while studying RCM lol.

If I were to focus on interpretation and musicality, is this really enough to fill a whole lesson? Because the content sounds very short on paper. What else can I do to make the lesson more fulfilling?
