Singing Heart Attack: what your voice is in for
Heart Attack is a two-gear song. The verses sit in a conversational middle register where almost anyone can talk their way through, then the chorus fires the melody up toward the top of the researched range, F3 to F5, and holds it there. The moment that decides whether you can sing this one is the first chorus lift: if that jump lands clean, the rest is stamina, because Demi Lovato keeps returning to the same high shelf, and the post-bridge chorus stacks the longest held notes of the night.
The technique the hard moment demands is a supported belt with a relaxed jaw: the top notes are sustained, not tapped, so pushing from the throat runs out fast. Mezzo-sopranos get the friendliest deal here, with the F5 ceiling landing exactly on the top of the mezzo band. Sopranos will find the tessitura comfortable but the verse lows sit under their floor. For altos the page's key math suggests just one semitone down, to E minor, which softens the chorus without changing the song's character. Tenors and lower voices are fighting the whole architecture, not one note.
Practice cue: loop the pre-chorus into the first chorus line at half volume, gliding rather than belting, until the leap feels like one gesture. Volume comes last.
