Singing Apt.: what your voice is in for
The numbers announce a duet before the first chord does: the researched range runs C3 to D5, a 26 semitone span that no single voice is meant to wear in one costume. Rose & Bruno Mars split the architecture between them, playful low-middle phrases holding down the floor and answering hooks that spring toward the D5 ceiling. For one singer, the deciding moment is simply choosing a half: this is a choose-which-end-hurts span, and the honest fix is octave strategy, not heroics.
Tenors sit exactly on the C3 floor but face five semitones over the ceiling, so they should own the lower half and flip or drop the brightest hook. Altos are the mirror image: the peak lands exactly on their ceiling while the lowest phrases sit five semitones under their floor, easy to nudge up an octave without anyone noticing. Mezzos clear the top by three semitones but float nine above the written floor. No verified key is stored on this entry, so pick the half you will sing at full voice and adjust in small two or three semitone steps from there.
Practice cue: sing one chorus twice today, once as each voice. The exercise maps exactly where your seam between chest and head voice lives, which is the real prerequisite for this song.
