Kenny Loggins | This is It

This 1979 release by Kenny Loggins, with co-writing, keyboards, and back-up vocals by Michael McDonald, features the harmonic complexity for which both artists are known. The bridge starts at 2:43, shows signs of a big change on the way at 2:57, and wraps up at 3:06 as the modulation hits.

According to Loggins, the melodic and harmonic ideas for the tune were finished long before the lyrics. The songwriting team had initially focused on a crossroads moment in a troubled romantic relationship. But the topic shifted to an adult son encouraging his ailing elderly father to fight hard for his health in the face of a worsening medical condition — a slice from Loggins’ own life. An unlikely hit, for sure, but it reached #11 and won a Grammy.

Hall + Oates | Method of Modern Love

By the mid-80s, Hall and Oates had scored a huge number of hits — more than any other duo in history. While 1984’s “Method of Modern Love” isn’t among the band’s top layer of major hits, it features a fun, goofy video concept, a shimmery modulation at 3:50, and a document of what might have arguably been pop music’s “peak mullet” moment.

Genesis | Turn It On Again

One of the singles from Duke, Genesis‘ 1980 album, “Turn It On Again” features plenty of modulations — as well as mixed meters! This album marked the band’s biggest departure from its “prog” rock origins towards its later pop-friendly material — all the while never losing its infectious harmonies. Phil Collins serves yeoman’s duty on both vocals and drums.

0:48 transitions up a half step, then back to the original key at 1:03; back up at 1:17, then back to the original key at 1:26. We start the cycle again with verse two at 1:34. Plenty of pedal point on this track, with the bass note remaining static while chords change above.
