Using a Nelson Riddle trick, I arranged the first chourus, and took a figure from that over a chord progression for the Intro.

I used a little Modal interchange for the Intro progession.

Form

Key of G major, modulating to Ab major.

Standard modulation but works well on this high energy song. Also pushes the vocal to the upper register, more oomph.

Bookends

Using a Nelson Riddle trick, I arranged the first chourus, and took a figure from that over a chord progression for the Intro.

I used a little Modal interchange for the Intro progession, and repeated for the end. The minor chords provide a nice contrast for this very “major” song.
