what is the question you are trying to ask here, or are you just telling us that
I'd say that the technique of satire used by Wilde in The Importance of Being Earnest is b. ridiculously exaggerating the importance people such as Gwendolen place on a name.

They needed to "draw level" with the others.
My best answer would be that out brain makes connections. Music can make a conection to what ever we're seeing/feeling in the moment. That's why certain songs might make us sad or happy, or any other emotion. Music can also help you concentrate, depending on the person.
