Can you sing Un Poco Loco by Miguel (Coco)?

Un Poco Loco, the festival number Miguel (Coco) delivers in the film, is sneakier than its party face: the researched range runs G3 to E5, a 21 semitone span, and the deciding moment is the closing climb, where the melody whips upward to E5 in the final celebratory push. Before that it bounces through syncopated middle register phrases that reward rhythmic play more than power. The technique is a bright, forward mix that can flip to an exhilarated top without weight; carry chest voice up that last run and the moderate difficulty turns punishing fast.

Mezzos come closest: one semitone of headroom above the top, with the G3 low dipping two under their floor, brief enough to sketch. Altos face two semitones over the ceiling on that final ascent. Sopranos keep five semitones of ceiling but lose five at the bottom, so a two or three semitone lift centers it nicely for them. Tenors sit seven over the top, beyond honest transposing range, and should either restyle the climax down an octave or hand this one to a higher voice. No verified key is stored on this entry, so all of that stays directional.

Practice cue: sing the final run on a rolled r or a lip trill five times before you ever add words. The trill forces the release the top note needs, and it makes the wildness feel easy, which is the whole charm of the song.
