Supertramp | Dreamer

The UK band Supertramp created material that’s a bit tough to categorize; their tune “Dreamer” is no exception, landing somewhere between pop tune, nursery song, and schoolyard taunt. “Dreamer,” a pop hit in two different decades (the studio version went to UK #13 in 1975; in 1980, a live version hit US #15 and Canada #1).

The tune starts in D major, dips into a gentler section in C major at 1:25, and finally returns boisterously to D major at 3:05. There are several other passing extra-key oddities here and there, as well.

Stevie Wonder | Where Where You When I Needed You

Another gem from Stevie Wonder‘s deep catalog of classics: “Where Were You When I Needed You.” Released as a B-side in 1972, it was one half of a two-part medley (along with “Superwoman”). The sound was truly ahead of its time, featuring multi-layered synths and state-of-the-art production. Key change at 2:06.

Seals + Crofts | Summer Breeze

Seals and Crofts‘ 1972 release “Summer Breeze” features an aural illusion — an apparent modulation where one doesn’t actually exist. The bridge (2:06 to 2:20) is built exclusively on compound/hybrid chords and a soaring vocal line that is unquestionably the high point of the tune. As we arrive back at the final verse at 2:20, it feels as if the tune modulated — all the cues are there. But we are still in the original key of E minor!

Dave Edmunds | Girls Talk

The 1970s post-punk UK songwriting scene brought to light many dynamic songwriters and performers — including Elvis Costello and Dave Edmunds. The original version of “Girls Talk,” written in 1979 by Costello, clocked in at only two minutes in length, as bare-bones as could be. Edmunds’ cover version, released the same year, added plenty of new features, including a fuller sound and three modulations: the first at the end of the intro (0:11); the second for the duration of an instrumental verse (2:07); and third, returning to the main key at the end of that verse (2:22).

The Crusaders feat. Randy Crawford | Street Life

Stacked with compound chords from its very first measure, “Street Life” (vocalist Randy Crawford, along with The Crusaders, featuring Joe Sample) was one of the most harmonically rich hits of the Disco area (1979). Modulating up a half-step at 1:33, the compound chords hit again around the 2:00 mark, dropping us back into the original key — and then up again at 3:32. The track made a strong appearance on the US pop, soul, and disco charts and hit #5 on the UK pop charts.
