Using any instrument, you create a sequence of perfectly normal sounds that becomes an affront to one’s auditory senses, yet somehow flows perfectly as ‘music’, severely distracting those who listen to it. Any creature that hears this ‘song’, the caster excluded, rolls disadvantage on everything. This includes damage rolls, unless they are made against the caster in which case the damage rolls are made with advantage. This spell cannot be shortened or extended, but can be canceled as per usual concentration rules. If the spell reaches the natural end of its duration, all affected creatures are stunned for one round.
