Slow, slow, fresh fount, keep time with my salt tears; Yet slower yet, oh faintly gentle springs (1-2).
Maestro Echo asks the "fresh fount" to "keep time" with her "tears." Could her tears be making music? Could nature be singing along? It sure seems like it.
List to the heavy part the music bears (3)
The lines tell us that the "heavy part" – the sad part – is borne by the music. What's weird here is that it's not Echo who's sad. It's her song. She's blaming it on the music.
Woe weeps out her division when she sings (4)
The word "sings" rhymes with "springs" in the second line, which draws a connection between the art of singing and rebirth. Maybe, just maybe, singing is the key to ending sadness and other bad things.
