Caleb Hyles has the low end richness or a Baritone, but the range of a Tenor. What singing voice type is this, and if I'm correct that he's a Baritone, how does he sing so damn high with ease?
I guess you'd call this style 'Contemporary Music Theatre'. Free from opera's requirement to match orchestral volume unamplified, singers often manage to integrate chest, head and falsetto into one 'voice'. Good, isn't he!
