"Murmur,a little sadly,how Love fled" "Murmur" means to whisper quietly in a very soft or gentle voice. The best example probably is how you whisper soft or gentle words to a baby to sooth it. Here, the speaker is saying in a very soft, gentle and sad voice (probably to themselves) how love has escaped them. It seems the speaker is upset at a broken relationship and is saying to themselves very softly and sadly how love has gone from their life. The writing is very poetic. It is not what you would usually say or express in your usual writing or conversation.
