Tutorial on Sor's B minor Etude

A tutorial/ lesson on Fernando Sor's B minor Etude. This tutorial is meant as a aid aimed at helping my students. However, I hope that it is of help to anyone standing to benefit from it.
As usual, my first advice is to get help from a great teacher. You may find great tutorials on youtube. Yet, such tutorials will never replace the detail a great one-on-one instructor may provide you.
Enjoy!
