The sound of silence is also called "the sound of silence". What kind of connotation does it express, love, friendship, or?

What is the song Silence? Apart from the landlord's opinion, I understand it this way: music begins with the singing of birds. I think the composer wants to leave the complicated world and come to this mountain forest to enjoy the natural peace and breathe the pure air. My opinion is gone.
