Can you sing Poison Poison by Reneé Rapp?

Reneé Rapp writes venom with a smile, and the vocal writing matches: conversational verses that sit low and dry, then a chorus that flips into full throated exasperation. The researched range runs F3 to D#5, a 22 semitone span, and the deciding moment is the first chorus flip, where the melody jumps from speech register to its sustained upper notes almost without warning. The technique is the transition itself: you need a low register that speaks and a belt that arrives with no gear grinding between them.

Altos are the closest casting, with the low note landing exactly on their floor and just one semitone poking over the ceiling. Mezzos keep two semitones of headroom up top but sit four below the floor; a two semitone lift spends their headroom and still leaves the deepest notes slightly under. Sopranos carry six semitones of ceiling room and sit seven below the floor, so a five or six semitone lift gets them close, with the very bottom still a shade low. Tenors clear the bottom by five semitones but face six over the top, making a five or six semitone drop their honest direction. No verified key is stored on this entry; set it from the chorus flip.

Practice cue: siren from your speaking pitch up to the chorus register ten times before singing the flip. The slide teaches the path the leap will take.
