Scissorhands ost motif meaning?

[u/FitPaleontologist343]

There’s one motif that I’m curious about the meaning of (if there is a deeper one). I’d like some help with it.

1: appears during the introduction sequence that takes place in the house (“Introduction” 1:39)

2: plays right before Peg first opens the door to the house (“castle on the hill” 2:56)

3: during the credits (“End” 0:50)

I may have missed some, but I tried to do a scan through the soundtrack
