Question

I need to write an interpretation and meaning on the song "embers" by max richter(search it on youtube! :)). Since I also need to choreograph a dance to this song for my dance class, I have decided to rename the song(which is my dance routine's name) as "Swallow". I do not know why I called it "swallow", but somehow it inherently feels right, so I want to know your interpretation of the meaning of the song mentioned above, and possibly connect it to the word swallow(maybe not as in eating) indirectly and metaphorically.
