Adele‘s “Set Fire to the Rain” is a power ballad built on orchestral strings and a programmed drum loop, and it became the third consecutive American chart-topper from her 2011 album “21.”

How Adele’s Demo of “Set Fire to the Rain” Became a Hot 100 No. 1

The song was written by Adele and producer Fraser T. Smith at his MyAudiotonic Studios in London during the “21” sessions. Smith had built his reputation on UK rap and pop, working with acts like Tinchy Stryder and Taio Cruz, and Adele asked him for something more rhythmic than her usual ballad approach. As Songfacts recounts, he answered by programming a tom-tom loop that became the foundation for the entire track. In a production breakdown for Sound on Sound, Smith explained that he cut the rhythm bed on an Akai MPC 4000 and wrote the piano part on a modest Yamaha upright, which he still rates as one of the best purchases he ever made.

Like the rest of “21”, the song comes out of the collapse of Adele’s first serious relationship. She has said the album “broke my heart” to write, according to American Songwriter, and that hearing fans embrace it was part of her recovery. There is also a good what-if in the credits. Adele had planned to record the final version with Rick Rubin, who produced several tracks on the album. Instead, as Stereogum lays out in its Number Ones column, she returned to Smith and kept her original demo vocal. Smith played piano, guitar, and bass himself. Session veteran Ash Soan added drums, and cellist Rosie Danvers arranged the strings. The version you hear on the radio is, in effect, the demo with an orchestra bolted on.

“Set Fire to the Rain” hit number one on the Billboard Hot 100 for the issue dated February 4, 2012, ending the ten-week run of Rihanna‘s “We Found Love” at the top. As Billboard reported, it was the third Hot 100 number one from “21”, making Adele the first solo act to lead the Billboard 200 albums chart while simultaneously scoring three number-one singles from a single album. American Songwriter notes that the sequence of “Rolling in the Deep,” “Someone Like You,” and “Set Fire to the Rain” also made her the first British woman to notch three straight American number ones.

That peak is stranger still because Adele was mostly silent while it happened. In November 2011, Billboard reported that she had undergone laser microsurgery in Boston to repair a recurrent vocal cord hemorrhage, after cancelling her US and UK tour dates. She was recovering from throat surgery as the single climbed. No standard music video was ever filmed. A live performance from her Royal Albert Hall concert film served as the official clip, and that same rendition went on to win the Grammy for Best Pop Solo Performance at the 2013 ceremony, as American Songwriter records.

Inside The Score of “Set Fire To The Rain”

Musically, the track sits in D minor, a single flat in the key signature with F major as its relative. Much of its force comes from how plainly it is assembled. The verse rides a repeating four-chord loop drawn from D minor, F major, C major, and G minor – i, III, ♭VII, and iv – an Aeolian pattern common to anthemic minor-key pop and, usefully, one that holds up in whatever key a sheet-music arrangement transposes it to. The telling chord is the C major. As the diatonic ♭VII of D natural minor rather than a dominant built on a raised seventh, it gives the verse no leading-tone pull, so the loop circles back to D minor without a dominant-to-tonic resolution. The verse stays entirely within the notes of natural D minor, with no raised leading tone pulling toward the tonic, and that circling quality is a big part of why the song stays restless even as it drives.

The rhythm is what Adele asked Smith for, and the official sheet music names that quality outright. Its tempo marking reads “Fast, with a Pop-Rock feel,” at 100 beats per minute (though it’s commonly noted elsewhere as 108bpm), which is not how most listeners remember a track filed under power ballad. Smith’s programmed tom loop holds a steady, near-marching pulse under the verses, pushing them forward where a piano ballad would usually drift. When the chorus arrives, the arrangement opens wide. Danvers’s strings swell in over a fuller drum kit, and Adele digs into the top of her chest voice for the “set fire to the rain” hook, belting near the ceiling of her range rather than slipping into head voice. The written dynamics carry that build, climbing from an opening mp to ff by the choruses, and no gear-change key modulation waits at the end, the stock trick in ballads this size. The song just gets louder and denser, which keeps Adele’s voice at the center. Structurally, it stays conventional, a verse and pre-chorus feeding a big chorus, with nearly all of the lift coming from dynamics and arrangement rather than harmonic complexity.

More than a decade on, the song has found a second life as spectacle. At Adele’s Caesars Palace residency in Las Vegas, which opened in 2022, she performs it in front of a wall of falling water while a piano on stage catches fire and collapses, per Songfacts. The staging leans hard into an image with a very ordinary backstory. By Stereogum’s account, the title came from a night when Adele stormed out of a restaurant mid-argument and struggled to light a cigarette in the pouring rain.
