Throughout "The Great Gatsby," Daisy's voice often changes. Most often, it changes through emotion. Fitzgerald, through Nick, tells us that Daisy "cried" statements when she's upset, for example. The most extreme change, though, comes from the point when Gatsby speaks of Daisy's voice in the past, when they first met, when he says it was "full of money," to the point when everything falls apart with their relationship, when Tom denounces and exposes Gatsby. At that point, Daisy's voice is commented on several times, and it is said to be "an octave lower," full of scorn, and then cold.
