This video embodies the delicate nature of the lyric along with the resilience of withstanding hardship," She continued "It was very important to me to have the sounds present on the track represented visually as well. The second the strings touched the bow, everyone in the room became remade. It was the moment that the typical rush of a video shoot became still and sobering. I'm deeply grateful to all who were a part."^[13]
