I don't think I mentioned this here, but one of my musical projects for 2018 is to figured out at least one part for every song on Alone in the Universe. Yester-day I figured out some parts for "Dirty to the Bone" and discovered an interesting feature.
There's a repeating guitar phrase that's something like:
And so on.
The title phrase ("dirty to the bone") is sung to this musical phrase:
These two parts consist of the same three pitches (G, B, and C), which gives the song some cohesion.
That the title phrase descends also gives a musical impression of going to the very core or - as the song puts it - "to the bone."
