Last night, I figured out the guitar phrase and chords in "Whatever's Right" and noticed a few interesting musical features.
Like the riff in "Last Train to Clarksville," the first two notes of the guitar phrase are Gs an octave apart. Both songs were written by Tommy Boyce and Bobby Hart, so I think this might be an intentional resemblance.
While the song is in G major, there are quite a few chords that contain accidentals: E major (G# accidental), A major (C# accidental), C minor (Eb accidental), and D minor (F natural accidental). This disregard of what notes "should" be in G major musically represents the sentiment of the song: "I know that you'll do whatever's right."
At the end of the line "And even if it doesn't turn out like I planned," the chords change from C major to C minor, which musically demonstrates the feeling of disappointment in that lyric.
