The Four Principles of Representation

If I couldn't play or say if I'd injured myself today before and I had to do a lesson I mightn't be able to make the practice tasks very representative because I can't really play but what I would do is I'd make sure that I respect the other four principles as much as possible. functional variability or represent or reputation without repetition is one and then manipulate attention and focus is one so like that's having an external focus of attention. In private lessons it doesn't necessarily always have to be representative but you want to keep it as representative as possible.
