The chord progression of "Hook" is very similar to the basic structure of
Pachelbel's
Canon in D,
[2][3] (D-A-Bm-F#m-G-D-G-A, or I-V-vi-iii-IV-I-IV-V),
[4] but transposed to the key of A major. This chord progression is very widely used in popular music, often as the hook, leading to other satirical takes on the use of this chord structure.
The song's lyrics, aimed directly at the listener, assert that the lyrical content of any song is effectively meaningless, as the song's musical hook will keep listeners coming back, even if they are unaware of the reason. In the introduction,
John Popper sings:
"It doesn't matter what I say / So long as I sing with
inflection / That makes you feel that I'll convey / Some inner truth or vast reflection."
This is followed by more lyrics about how he has nothing to say. These lyrics are a satirical take on the formulaic way popular music is generated. Further on in the song however, the lyrics become even more blatant, claiming that formulaic music is an easy way to make money "When I’m feeling stuck and need a buck/ I don’t rely on luck, because/ the hook brings you back...”
The musically "lazy" chord structure viewed in combination with the
meta-lyrics reveal the true extent of the song's "genius": "the commentary is a big joke about how listeners will like just about anything laid on top of the chords of the infinitely clichéd
Pachelbel canon, even lyrics that openly mock them for liking it.
