She also credited Epworth for her increased vocal confidence, stating, "He brought a lot out of me . He brought my voice out as well--there's notes that I hit in that song (" Rolling in the Deep ") that I never even knew I could hit ." According to reviewer Bill Lamb, "Rolling in the Deep" features "martial beats, pounding piano keys and chanting backing singers". Adele's vocals have been described as having a "hint of Wanda Jackson's dirty - blues growl". According to Nadine Cheung from AOL Radio Blog the song is "sung from the perspective of a scorned lover, who is finally able to see the light, but despite regretful sentiments, reconciliation is not an option here ." "Rolling in the Deep" is written in the key of C minor (B minor for live performances), in common time with a tempo of 105 beats per minute . The accompaniment uses open fifths, in a progression of C--G--B ♭--G--B ♭ . Adele's voice spans from B ♭ to D, the highest note sung using the head voice . </P> <P> The song was reportedly inspired by a Nashville - schooled US tour bus driver, and composed by Epworth and Adele in a single afternoon following Adele's breakup with her boyfriend . It was "her reaction to,' being told that my life was going to be boring and lonely and rubbish, and that I was a weak person if I didn't stay in the relationship . I was very insulted, and wrote that as a sort of "fuck you"."' </P> <P> Rolling in the Deep received widespread critical acclaim and was cited by various critics and publications as the best song of the year . The Sun called the song "an epic, foot - stomper of a pop anthem with thumping piano and a vocal you would expect from a veteran of 20 years on the road ." Lamb gave it a score of 5 out of 5, saying: "' Rolling In the Deep' (...) wastes no time in presenting the stunning bluesy authority of her voice...Here is a voice that can raise chills up the spine, and, when she is in a mood like this, the sense of foreboding will rivet your attention ." Jason Lipshutz of Billboard magazine complimented the song's "sweeping chorus" and felt that the song "places a similar emphasis on its refrain but its multilayered instrumentation gives the English singer's wail a previously unheard depth". Lipshutz said, "Adele's noticeable leap in vocal confidence highlights the track . She gracefully lingers on the last line of the verses and attacks the sorrowful chorus' first words,' We could have had it all,' head on ." Rolling Stone magazine's Barry Walters stated, "' Rolling in the Deep' finds the 22 - year - old in bluesy gospel mode, sounding powerful but not particularly pop . Starting with a stroked acoustic guitar, this breakup - mourning track builds to a stomping, hand - clapping climax that affirms the British knack for rejiggering the sound of American roots music ." </P>
