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.

Queen | The Show Must Go On

Released only six weeks before Freddy Mercury‘s passing at the end of a brief battle with HIV/AIDS, “The Show Must Go On” (1991) reminded Queen fans worldwide of this global supergroup’s originality and vision. Mercury’s vocal timbre was changed by the disease, but he still pulled off a beautiful performance. Modulations at 1:32, 2:13 and 2:55.

Marin Mazzie | And the World Goes Round

Marin Mazzie, an incredible actress who starred in Ragtime and Passion (and more recently Bullets Over Broadway and The King and I) on Broadway, performed Kander & Ebb’s “And the World Goes Round” in 1991. Mazzie passed away at age 57 after battling ovarian cancer for three years. Key change at 2:53.

Stone Temple Pilots | Sour Girl

Stone Temple Pilots, fronted by the late Scott Weiland, released “Sour Girl” in 1999. The intro (through 0:19) emphasizes G major as a key area, although it also features a flat 7th. The verse (0:19 – 0:56) flips quickly back and forth from D major to D minor (an F# is featured on the melody line on the word “sour ” — coupled with the restless bassline, often suggesting D minor as it shifts as often as every eighth note — adds to the ambiguity).

A far more detailed and scholarly analysis of the tune can be found on the Aaron Krerowicz site.
