James Taylor | Enough To Be On Your Way

Far removed in time from his early hits, 1997’s Hourglass was a James Taylor album home to wonderfully woven stories, increasingly complex harmonies, and multi-layered textures. The artist described the collection as “spirituals for agnostics.”

“Enough to Be On Your Way,” reported to have been written in the wake of the death of Taylor’s brother Alex, is quietly stunning even before the modulation — but JT adds a key change to the mix at 4:35. The track features cello by Yo-Yo Ma.

Paula Cole feat. Peter Gabriel | Hush, Hush, Hush

“Hush, Hush, Hush,” a supporting track on Paula Cole‘s breakout 1996 album This Fire (the single was something about cowboys), guest features the singer/songwriter’s mentor, Peter Gabriel as well as some gorgeous and unusual instrumental features. Starting in a minor key, a transition to a major-key bridge starts at 2:01; at 2:33, we return to the original key. An unexpected 4-chord repeating harmonic progression loops from 2:50 to the end.

Deborah Cox | Nobody’s Supposed To Be Here

R&B chanteuse Deborah Cox released “Nobody’s Supposed to Be Here,” the track for which she’s perhaps best known, in 1998.

“‘The song crossed my path in early ’98. I had taken a little time off — I got married in Jamaica — and was really searching for a direction for the second album,” (Billboard). “When Anthony ‘Shep’ Crawford and Montell Jordan (the co-writers) played it for me, I immediately knew the song was a smash. I just remember hearing it and going, ‘Oh my God, this speaks to me!’ I had just gone through the same thing: I was caught off guard with the love of my life, so it really resonated.”

This gospel-infused ballad builds to a big modulation at 3:00.

Duncan Sheik | Barely Breathing

Duncan Sheik‘s tunes are full of quirks — harmonic and otherwise — but fewer full modulations. His best-known hit, 1996’s “Barely Breathing,” sticks to fairly straightforward territory through the first two verses and choruses. But then the bridge (2:40) presents several short but compelling key-of-the-moment segments (I major / V minor pairs) that don’t closely relate to the rest of the tune — but then, that’s often true of a good bridge. By 3:09, we’re ready to dive back into the familiarity (and relative simplicity) of the chorus as it reverts to the original key.

Andrea Bocelli | Because We Believe

Bocelli’s “Because We Belive” has a textbook example of a “common tone” modulation: a single note is sustained through key change, thus transforming its harmonic function. And the second, at 4:20, is the rare downward modulation, moving from E to D. David Foster is at the keys (he co-wrote the song with his daughter Amy for the 2006 Turin Olympics).
