Though this is definitely sung in the upper octave, I would have to say that Tahj held his own vocally. With the quick little trills and runs to refresh the vocally straight song, it was cool. His tone is clearly audible with a light nasally sound and a little bit of vibrato. With some vocal lessons, he can strengthen and smooth his vibrato out so it can be less noticeable when she sings. I can hear him on the radio...a mini Ne-Yo or Trey Songz!
