Hoe speel je piano?

Links to the website videos didn't work. He says to go slow, 2 bars at a time, and then keeps talking about the next ones, with no indication where to actually find the bars I was supposed to be practicing before moving on. Finally found the sheet music at the end but that wasn't clear....maybe this works better as a physical book? The sheet music image was also super tiny, I had to take screen shots so I can expand enough to read it. There's also a sentence “And bankers.” (To pay attention to) with no definition what bankers are in a musical context. I searched the internet, my piano playing partner looked it up...just confusing.

He says hand placement is super important, which is partly why I wanted to start with a book. But he doesn't really talk about how to identify hand placement for any new pieces. A little orientation to bass clef was helpful but generally all I learned from this was a suggestion of a good piece of music to start my learning.
