Those who break into tears simply by humming to themselves have no need or concern for musical instruments like the harp and organ.

This couplet captures an emotional depth so raw and delicate that it requires no external orchestra. The poet suggests that someone who weeps simply from their own quiet humming is already tuned to the deepest chords of sorrow. For such deeply sensitive souls, grand instruments like the harp or organ ('chang' and 'arghanun') are completely redundant, as their own tender heart is the truest music.
