In MacFarlane's view, the Beatles "chose to employ an overarching thematic concept in an apparent effort to unify individual tracks". Everett contends that the album's "musical unity results ... from motivic relationships between key areas, particularly involving C, E, and G". Moore argues that the recording's "use of common harmonic patterns and falling melodies" contributes to its overall cohesiveness, which he describes as narrative unity, but not necessarily conceptual unity. MacFarlane agrees, suggesting that with the exception of the reprise, the album lacks the melodic and harmonic continuity that is consistent with cyclic form.
