Dancing instead of singing? Does your DM allow her to cast spells while dancing?
IF so, BAD DM!!!!!
Why not? The PHB says that the somatic components required for bard spells are relatively simple... specifically in reguards to no arcane spell failure in light armor, but why not expound on it?
A dervish enters a "Dervish Dance" and gets bonuses to attacks... why can't a bard mesh in the "relatively simple" somatic components into an eloborate dance movement? Any verbal components are secondary to the bard's prefered way of releasing the magic from within.
Never punish creativity! It's not just a clever .sig!
Adjust the rules to your game, instead of your game to the rules... you and your players could have a much more rewarding experience.
Have you never been moved by the graceful moves of the ballet dancer, or greatly impressed with water ballet? Have you ever laughed out loud when moved to happiness, or cried when moved to tears by the graceful performance of the dancers in Swan Lake? Can you deny the electricity you feel from watching Stomp? Have you ever felt your heart leap when watching the prima ballerina in River Dance jump and flit her way around those that would suppress her?
Allow bardic dancing for Fascinate, Inspire Courage, Inspire Competence, Inspire Greatness, and Inspire Heroics with no verbal components needed. Instead you can say that the allies must have line of sight to the bard, and maybe even a maximum distance from the bard.
You can even allow Suggestion and Mass Suggestion with dance, but with some verbal components. Heck, one girl danced once, and soon after John the Baptist's head was on a silver platter. If that's not the power of dance, I don't know what is.
