“Fall In Line” by Christina Aguilera (featuring Demi Lovato) is the second single from the album Liberation (2018). The New York Times calls the track “a defiant dirge addressed directly to ‘little girls’ … it insists, ‘You do not owe them your body and your soul.’” The key change is at 3:00.

The Apex Project | Home

The Apex Project, featuring vocalist Cheeyang Ng, covered “Home,” a tune made popular through Singapore Day. The event travels to cities worldwide with large numbers of overseas Singaporean nationals with the goal of helping them remain connected to their home country. This beautiful 2016 a capella rendition of the tune, which was also arranged by Cheeyang, modulates at 1:59 and 2:56.

Player | Baby Come Back

“Yacht Rock” royalty, Player’s polished southern California sound was all over the charts in the late 70s. Multiple lead vocalists, complex chords, and tight vocal harmonies were some of the band’s hallmarks.

For “Baby Come Back,” the band’s smash 1977 hit, the modulation lasts for the duration of the bridge (2:23 – 2:48) before reverting to its original key.

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.

Chicago | Hard Habit to Break

“Hard Habit to Break,” a 1984 power ballad, was one of Chicago’s biggest hits and part of the band’s era of increasingly pop-friendly tunes. David Foster, well-known for producing lush songwriting, was one of the song’s co-writers and arrangers at this time, layering the band’s trademark horns with towering strings and synth saturation like there was no tomorrow.

The modulations are everywhere: 0:35, 1:00, 1:32, 1:56, 2:19, several quick pivots during the bridge around 3:12, and 3:18.
