Prayer ?

How does prayer work?
Does it work in the same way as Pheromones do for bees?
Or is it the perfect resonance of one's voice(s)?
As in the case of the Tacoma Narrows Bridge (or an opera singer's voice breaking a glass), resonance has power beyond what is visible to the naked eye (although the effects of it can be seen).

Everyone has had an experience with a song that inspires, be it - the Theme From Rocky, a Wagner arrangement or a primitive war chant.
Music is also said to soothe the savage beast.
Is it the melody or the perfect pitch that creates this effect?
Is it a prayer to one's inner self?
