Today we’re focusing on “What Becomes of the Broken Hearted” (1966) by Jimmy Ruffin. The website Overthinking It has a great writeup on the tune, which we won’t even try to improve on:
The tune “goes from Bb major to C major when it moves from the verse to the chorus, which is as cheesy a modulation as you could hope for. But damn if the songwriters don’t work for it.
The basic structure of the verse is ingenious enough to begin with: I->iii->vi->IV->V->I (notice how much time it spends hanging out on the minor chords of iii and vi. This is one of the saddest songs ever written in a major key.) As it moves towards the chorus, the pattern changes ever so slightly. After landing on vi, instead of going down a third to the subdominant, the harmony just reverses course and moves back to iii. This is a totally orthodox harmonic move (root motion by a fifth is pretty much always allowed) but it destabilizes the harmony enough for the new key in the chorus to seem like an arrival, and not merely an extravagance.”

In addition, quite a few of the chords have inverted voicings, only adding to the ambiguity. The track went top 10 in the US, UK, and France and has since been covered by a range of artists including The Supremes, Joan Osborne, Boy George, and Joe Cocker.
