Hand Independence
Pay special attention to how your left hand moves from note to note especially during wide jumps. All movements should be smooth and limber. The piece is reasonably slow and you can make use of. The wrists should be free to pivot wherever necessary, slow the piece down even further to accommodate these principles.
There is also one instance of a 3 against 2 rhythm towards the end of the piece. Take your time with it. It will be useful to know very well once you get to Opening from Glassworks by Philip Glass a little further into the course.
This piece is relatively short and repetitive, so I recommend learning it in its entirety. You can find the rest of its tutorial parts here.
