Act 5, Scene 1: As Portia approaches, what is her comment on music and how does that comment fit in with the comment about the brightly shining candle?

Portia comments on how both light and music can have different emotional reactions depending on the context they are seen and heard through. Light from a king is shines brighter than light from a lower ranking man. Similarly, Portia points out that music at night sounds much better than during the day.
