I am thinking that these are all for advanced students. I would not have that kind of control at this time, even though some of the concepts have been applied loosely here and there during my studies.
And yet I teach them to beginners, too. Certainly if I have a student who isn't practicing, we can't go into this kind of depth. Or if I'm working with someone on technique that never had that in their previous lessons, then the focus has to be undoing bad habits first since the moment they focus on something else they will go back to their old ways of playing.
But I firmly believe music is a human thing, and so we can learn to express even at simple levels, the teacher just has to know what pieces are good ones to approach this with, and when in the student's progress. But I have heard (not just from my own students) from people here who are beginners that play with these expressive techniques naturally. These are nothing "new" and "revolutionary" that will blow your mind, as they are what many people naturally gravitate to.
This is just a way of organizing what you may already do, as well as teaching what you may not yet do so you have more options in your playing
