The song has a decidedly Latin/pop feel.  It's a duet for male/female voices.  The female vocals require a light lyric soprano, in or around the C3 to C6 range (but not necessarily encompassing that entire range, as the music will be adapted to suit the right voice).   That said, I'm looking for a really expressive voice with a rich low end,  which can switch to a  slightly raspy  higher end when needed.  We're looking forward to hearing some of the amazing voices we know are out there.
