Yester-day I learned the vocal melody for the first two verses of "You Never Give Me Your Money," and in doing so I discovered something interesting.
I might be a bit off on the rests, but the melody is something like this:
The song is in A minor (at least this section is), but there's a G# accidental. In the lyrics, this corresponds to "you" in the line "And in the middle of negotiations you break down" in the first verse and "I" in the line "And in the middle of investigation I break down" in the second verse. The note's being an accidental sort of musically represents the "break[ing] down" of both "you" and "I."
