Can you sing Happier by Marshmello?

Bright production, high tessitura: the researched range runs D4 to A5, a 19 semitone span whose floor sits a whole step above middle C and whose ceiling reaches genuine soprano territory. The deciding moment is the final chorus, where the hook returns at the top of the span and asks for ringing, sustained high notes over an electronic pulse. The technique is supported head-voice power: brightness without shriek.

Sopranos fit the whole map, with the A5 peak landing exactly on their ceiling and 2 semitones of room below, so this is natural casting with zero top margin: warm up before attempting it. Mezzos face 4 semitones over the top, making a 4 semitone drop their honest setting, and altos sit 7 over, where a drop that size starts to change the song's character. Tenors and lower voices are an octave or more out of position and should take the melody down an octave rather than chase a transposition. No verified key is stored on this Marshmello entry, so set yours from the final chorus peak and leave a semitone of insurance if you sing at night.

Practice cue: slide up to your highest comfortable note on ng, hold it four counts, and smile slightly. That is the placement the last chorus wants for its entire length.
