Orsino, the lovesick duke of Illyria, speaks these lines. He introduces the audience to the theme of love as overpowering and fickle. He calls sweet music the "food of love" and wants "an excess of it" so that he can satisfy his appetite for it. However, when the music is no longer sweet, Orsino compares it to the sea. Like the sea, it engulfs everything and debases its value to a "low price." He concludes that love can change from sweet music to an engulfing sea in a matter of one minute. He also suggests that it shifts shape at whim. The fickleness of love reflects Orsino’s own inconstant nature, casting him as self-indulgent and melodramatic. Finally, because Orsino never names the object of his love in these opening lines, the emotional outpouring indicates that Orsino is consumed more by the idea of love than by love for Olivia.
It describes love as a flowers sweet smell and it makes music be the food of love. They want more music so that love may go on. But when the odor does not smell sweet the love is now over.
