Can you sing Smile by Avril Lavigne?

Smile is Avril Lavigne's pop-punk gratitude anthem, and it runs on her trademark contrast: bratty, conversational verses that sit low, then a chorus that launches into bright, sustained belt with the guitars at full crunch. The researched E3 to F#5 range spans 26 semitones, and the stored key is A major at 94 percent confidence.

The deciding moment is the chorus launch, a leap from the smirking verse register onto sustained top-third notes that must ring with punk brightness, chest-forward, edgy, but never actually shouted. The 66 difficulty score lives in that landing. The technique is pop-punk belt-mix, bright and slightly bratty vowel shapes over genuine support, with the attitude doing half the acoustic work. Mezzos fit everything except one stored ceiling semitone and take the two semitone lift to B major per the page's key math. Altos are one semitone shy at the floor and four over the top; the math gives them a one semitone drop to G# major. Sopranos take the five semitone lift to D major. Tenors face nine semitones of ceiling and start from the six semitone drop to D# major, accepting that the sneer transposes better than the scream.

Practice cue: speak the chorus line in full teenage-eye-roll character, then sing it keeping the exact same face. The attitude tunes the resonance.
