music is played in a setting where other sounds and noises interfere and disrupt it, the music is not valued or appreciated properly. People may overlook its goodness and beauty.
When Lorenzo and Jessica greet Portia, the lady still keeps up the pretence that she and Nerissa were in a convent all of that time and were praying for the success of her husband’s venture. However, Portia also warns Lorenzo and Jessica not to mention her absence to Bassanio and Graziano.
When Bassanio and Graziano return home, Bassanio praises the beauty of his wifebytelling her that she is as radiant as the sun (impliedbythe suggestion that when the sun is on the other side of the world – “the Antipodes” – Portia can take the place of it and turn the night into day: lines 126-27). The witty Portia uses the mention of sunlight as a means to begin the fun and the teasing of her husband:
Let me give light, but let me not be light; For a light wife doth make a heavy husband, And never be Bassanio so for me.(128-30)
By the expression “a light wife,” Portia means a wife who is light or not serious in her faithfulness to her husband. A light wife is an unfaithfulwife.
