Music of the Spheres

With this spell, the priest creates tones and harmonies of such unearthly beauty and complexity that they entrance the listener, making it difficult for the listener to attack or otherwise harm the priest. The listener receives a normal saving throw against this effect. Failure means that the listener is entranced and is unable to attack the priest for the duration of the spell.
In addition, the music makes the subject gullible and more susceptible to charm magics such as charm person, suggestion, and hypnotism. While the music spell is in effect, the subject saves against charm spells with a -3 penalty.
This spell does not protect other characters in company with the priest; listeners who have fallen prey to the music are free to attack anyone else. The spell effect ends instantly if the priest takes any hostile action against a creature under the influence of the spell.
Music of the spheres can affect one creature per three levels of the priest (one subject at 3rd level, two at 6th level, etc.). Subjects must be within a 20-foot-diameter circle.
Potential victims must have Intelligence of at least 1 (necessary to understand the concept of music) and must be able to hear the music (i.e., they cannot be deaf and there can be nothing obstructing the victim's ears). This also means that the level of background noise must be low enough for the music to be audible. The DM should assume that the music is the same volume as an average human's normal speaking voice. If the potential subject could not hear speech at the appropriate range under prevailing conditions, the spell cannot affect that subject. The spell would be virtually useless in the midst of a full-scale battle or during a hurricane.
The priest strokes the bows (material component) together in an intricate sequence while casting the spell. The bows are not consumed in the casting.
