Paul Simon once wrote the lyric, “I seem to lean on old familiar ways.” And so it is for most songwriters, Simon included. When it comes to song structure, inertia is strong, and few writers deviate substantially from one of two general song forms: AABA (most jazz songs follow this format, many show tunes, and several pop songs as well. Think “Yesterday” by the Beatles) and, with modest modifications, ABAB (more identifiable as verse, chorus, verse, chorus, often adding a bridge after the second chorus). Composers do it almost without thought, which makes exceptions all the more impressive. Sure, it might not take a genius to write a song with the form ABCDCBA, but it’s not something that occurs to most people, so in that sense, maybe it does take a genius to compose a song in an interesting format, if only because no one else thought to do it.
Which means maybe JamesTaylor is a genius. His 1991 song, “Shed a Little Light,” follows that song form – ABCDCBA - and somehow makes it flow nicely and memorably. You would think after four sections foregoing repetition, the listener would be left to flounder, lost in a sea of unfamiliarity, but JT pulls it off impressively. Most listeners probably aren’t even aware that the song is proceeding to unexplored territory; they’re only aware that the song continues to move forward, to gain momentum, before reversing the momentum and slowing to a halt, as if completing a four-minute train ride.
