Why?Nonmagic? This sounds more like a "Minstrel" archetype for the Rogue class. Or, "Troubadour".
Rogues aren’t inspirational, IMO, nor can they normally affect groups of people into emotional displays, quiet a savage beast, or any number of other things bards one stories can do. Nor should Bards be Sneak Attacking as their primary combat contribution.
IRL, work songs literally make people work harder, and more effectively. It’s easy to imagine a bard giving bonuses to saves against Exhaustion without casting any spell or doing any overt magic.
