情歌无言只是爱离歌无言只是伤
[qíng gē wú yán zhĭ shì ài lí gē wú yán zhĭ shì shāng]
'Silent ballads convey nothing but love; silent parting songs leave nothing but wounds.' This implies that music (especially love or farewell songs) can be very expressive, stirring love, or leaving people sorrowful when they part.
