Well, don't know if this is exactly what you are asking, but:
In INTO THE WOODS, one of Sondheim's many motifs is the 'Bean Theme' (D-flat, G-flat, A-flat, F-natural, E-flat). It is used quite often throughout the show in songs and, particulary, in underscoring.
But what I love about it is that in 'No One in Alone' the motif shows up inverted.
The "People make mistakes" lyric is an inversion (D-flat, A-flat, G-flat, B-flat, C-natural) of the 'Bean Theme' that is planted thorughout the score.
I find it so exciting.
But maybe that's just 'cause I'm different.

The opposite of creation isn't war, it's stagnation.
