"Your magic comes from the rhythms and life force of the world"
So how about making our magic reflect that? Any spell cast from the Bard list, instead of doing the standard "Move hand, whispered chant" stuff, have the bard quickly whip out their lute and give it a simple strum. "Ritual spells" involve a longer music session.
While we're at it, how about making spells cast from Clerics/Souls/Paladins involve more prayer and less arcane gestures?
