An invisible wall of force springs into existence at a point you choose within range. The wall projects the cords played in magical rays. The wall appears in any orientation you choose, as a horizontal or vertical barrier or at an angle. It can be free floating or resting on a solid surface. You can form it into a hemispherical dome or a sphere with a radius of up to 10 feet, or you can shape a flat surface made up of ten 10-foot-by-10-foot panels. Each panel must be contiguous with another panel. In any form, the wall is 1/4 inch thick. It lasts for the duration. If the wall cuts through a creature's space when it appears, the creature is pushed to one side of the wall (your choice which side). 

Creatures on the offensive side of the wall must make a dexterity saving throw, or take 5d8 psychic damage. Half damage on a successful save. 

Upon hearing the music of the wall, unless a creature is immune to being charmed they must make a wisdom saving throw. If they fall, they have disadvantage on all ability checks as long as the wall is up. 

Nothing can physically pass through the wall. It is immune to all damage and can't be dispelled by dispel magic.
