[Toossehew]

Your interpretation of the song is pretty much identical to mine: the bell representing her artistic calling (and her desire to "blot it out," though before song's end it comes back out of the sea and tolls for her), the relationship sacrifices she has to make to devote herself to that calling, and the makeshift dove representing the simple life she longs for. My second favorite song on Ys and some of my very favorite lyrics on the record.
