Breh,
You can always tell who in these threads understands the topic, and who doesn't.
Most people who are in here talking on these topics, are clueless about singing.
I posted that Tank is a more "Agile" singer with more range than Tyrese, nobody who knows anything about singing would disagree with that statement.
I also posted that Tyrese has a stronger "Chest Voice" than Tank, also nobody with any knowledge about singing would disagree with that.
Tyrese is a great singer, but he has limited vocal range (compared to Tank), he tries and hit every single note in chest voice, rarely do you ever hear him attempting to go into any other "Vocal Registers".
On the contrary a singer like Tank is always playing with different Vocal registers, via rifts, runs, falsetto, head voice, etc...
