You have to move your hand a lot in this old Dutch Christmas song, sometimes even within a slur. In the third and fourth lines you see a symbol (a flat) in front of the B. That means that you should not play the B, but the B♭. That's he black key left of the B. At the E at the end of the third line you have to step over your thumb. At the end of the fourth line you even make a slightly bigger step with your index finger. But the last line is nice and easy!
