The spell created a large glowing image of a harp, which floated above the caster. The harp played by itself, continuing whatever song the caster sang or hummed during casting. It emitted twinkling radiance as it sang.
All creatures within 2 ft (0.6 m) of the harp were affected by the spell. Magical or natural pain, nausea, the effects of charms, holds, fear, stunning, and repulsion were eliminated and did not return after the spell expired. The caster could also focus the spell's effects onto a single creature, who was healed when the harp appeared.
The spell was self-sustaining, so the caster was able to cast another spell afterwards or even sleep without any negative affect on the harp. If the caster was killed, the spell continued but the harp turned a blood-red color and the song took on a sad tone.
