Dumplin's Song of Uncontrollable Footwork

You play any song of your choice on an instrument, weaving magic into the notes and enchanting any creatures within hearing. Creatures within hearing distance must roll a wisdom saving throw (Creatures that are deaf automatically succeed). On a successful save they are not affected, on a failed saving throw they are forced to dance uncontrollably. While dancing creatures cannot attack or move in  any direction, but they are able to cast spells requiring only verbal components.
