“No Good Deed” is one of the last songs on the Wicked soundtrack. In the story, it takes place when Elphaba fears she has lost her love, Fiyero, and faces the realization that all of the good she has tried to do has only turned out badly.
In addition to having great lyrics that explore the “moral ambiguities” that are the main theme of the show, the very beginning of the song contains another nice detail. After two bars or so of instrumental introduction, Elphaba screams Fiyero’s name. But instead of being an unpitched scream, she actually sings a high note that is a minor second above the tonal center of the song. (A minor second is an interval basically the same as a minor ninth, only the two notes are right next to each other instead of an octave removed.) This creates the effect of a scream, as the note is very high and dissonant, but it is much more controlled and musical than an actual scream. A nice touch.
