The Pearl Part 1

The first question I have about this book is about the motif of the music in Kino's head. What exactly is this music? Is it a reference to the old ways that they talked about in the beginning of the book? It seems as though The Song of Evil plays in his head every time something bad is about to happen. It's dead on too. It plays every single time something bad happens. If they mention the song, you can immediately predict something bad will happen. And the book never fails to prove your prediction right. The first time the Song of Evil was mentuoned was when the Scorpion stung little Coyotito. I don't understand why Coyotito laughed at the scorpion instead of suspecting danger. I understand he was a baby but scorpions dont really look friendly and we humans tend to be able to tell what is friendly and what is scary.
Next, why wouldn't the doctor help Kino if he offered him pearls. Even if they're small pearls, they're still pearls. They have to have some value. Plus he wasn't doing anything anyway and the baby was dying. That's awfully mean. He's only willing to help after Kino finds the Pearl of the World. That makes the doctor's character very greedy and dislikable. And why does the whole village go with them to see the doctor. It doesn't seem like the situation is any of their business. They even crowded into Kino's home when the doctor actually came to visit. That seems very nosey and I know I wouldn't like it.
During the night, what was the movement in the corner of Kino's house? Was it the doctor? Was it someone sent by the doctor to try and get the pearl? It was in the same corner that the pearl was in. And what struck Kino on the head? Did he hit his head or was he hit by whatever was causing the movement? The whole situation seemed very odd to me. And the book offered no explanation.that seemed awfully foolish. Especially because he promised his son would go to school even though Coyotito was right there dying from scorpion poison.
One last thing is why did Kino make all those promises about what he would do with his money?
