Toni Braxton | Unbreak My Heart

“Unbreak My Heart,” released in 1996 by Toni Braxton, is a Grammy-winning track (Best Female Pop Vocal Performance) written by Diane Warren and produced by David Foster. The tune stayed at #1 on the Pop chart for 11 weeks straight. When Billboard celebrated its 40th anniversary, the track was declared as the most successful song by a solo artist in the Billboard Hot 100 history. The verses are in the key of B minor, with modulations to D minor for the choruses and G# minor for the bridge.

An excerpt from SPIN journalist Charles Aaron’s review: “This exquisitely crafted, heart-pumping l-u-v song has been droning in the produce department of my grocery store for about a year now, but I’d just like to go on record as saying that if it ever stops, I’ll really be heartbroken.”

Tower of Power | So Very Hard to Go

Tower of Power‘s biggest US hit wasn’t one of the powerhouse uptempo funk tracks for which the band is famous. Instead, it was a ballad, “So Very Hard to Go,” which reached #17 on the pop charts in 1973. The verse and pre-chorus are in Bb major, but a modulation to G major hits at the chorus, reverting back to Bb major for the second verse, and so on.

Kelly Rowland | Stole

After gaining fame as part of Destiny’s Child, vocalist Kelly Rowland released “Stole” in 2002. The lyrics detail the anguish of multiple young lives lost to violence. The tune was a smash hit in the UK and Australia, but didn’t perform nearly as well in the US.

The form alternates between an intro and verse built around a Cmajor/Asus2 vamp and a chorus with a repeating Gmin/Dmin/Cmin pattern (first appearing at 0:45).

Mariah Carey | I Don’t Wanna Cry

One of Mariah Carey’s early hits from her debut album, 1991’s “I Dont Wanna Cry” (co-written by Carey and Narada Michael Walden) made it to #1 on the US Billboard Hot 100 charts. Carey’s first four singles performed identically, making her the first female artist and first solo artist to have all four first four singles reach #1 (The Jackson 5 did it first, as a group). After a big bridge, the modulation is at 3:25, made all the more powerful by compound chords at the transition.

Howard Jones | One Last Try

“One Last Try” was a 1992 release by UK New Wave/pop artist Howard Jones, perhaps best known for his 1984 hit “Things Can Only Get Better.” The tune shifts keys quite a few times, including E minor during the first verse, a clear shift to G major during the chorus at 0:38, and some E major during the instrumental bridge at 2:17, which features some lovely arranging for clarinet choir(!) and French horn.

The Fifth Dimension | One Less Bell to Answer

Among the top hits for legendary songwriting team Burt Bacharach and lyricist Hal David, 1970’s “One Less Bell to Answer” helped to cement the career of The Fifth Dimension.

Starting with Bacharach’s trademark torch song melancholy in the first verse, a more hopeful tone is reflected in the long bridge, which starts with a modulation at 1:07. An instrumental verse, beginning at 1:43, returns to the original key.

Elton John | Harmony

Elton John‘s smash 1973 album Goodbye Yellow Brick Road, considered by many to be the peak of his career, featured plenty of well-known tunes. “Harmony,” the humble B-side of the hit “Bennie and the Jets,” utilized Elton’s unique wall-of-sound multi-layered background vocals. It modulates back and forth between Eb minor and Eb major. Starting in minor, it modulates to major just before the first chorus (0:33), then back into minor for the next verse at 1:09, and then back to major at 1:31 through the short balance of this distinctive tune.
