Cue No. 17

At this point in the story, the trio heads into uncharted territory. This is not Hogwarts, London, or any location known in the series so far. The music centers around a single pitch for most of the cue; non-chord tones circle the hypnotic note as the montage shows all of the places the trio wander from location to location, staying hidden from Death Eaters. 

The key center does not change at all until the establishing shot of the mountains. The orchestra fills out at the end of the cue, complimenting the vastness of the landscapes seen in these shots. An absence of themes or familiar material is an intentional decision, as this is the first true unknown direction the trio has ever gone in.
