@Booker T Garvey in terms of those 10 techniques what do you think about these singers:
Tevin Campbell
Jackie Wilson
Sam Cooke
I think Tevin Campbell and Jackie wilson are about the same but they stayed in that tenor lane
Sam cooke is legendary absolutely, but his voice is classic raw gospel which i love, but we're talking about masters here.
This is why I listed will downing - he doesn't have the HITS like other artists, but vocally, he is a master.
His voice goes from tenor, baritone, and bass within a matter of seconds, most singers just stay in one range their entire careers, he just bounces in and out - here is an example (time stamped)

I know you're in character, but beyonce can't even speak clearly, let alone sing with perfect diction.
