Organ music 'instils religious feelings'

People who experience a sense of spirituality in church may be reacting to the extreme bass sound produced by some organ pipes.

Many churches and cathedrals have organ pipes that are so long they emit infrasound which at a frequency lower than 20 Hertz is largely inaudible to the human ear.

But in a controlled experiment in which infrasound was pumped into a concert hall, UK scientists found they could instil strange feelings in the audience at will.

These included an extreme sense of sorrow, coldness, anxiety and even shivers down the spine....

...The results showed that odd sensations in the audience increased by an average of 22% when the extreme bass was present.

"It has been suggested that because some organ pipes in churches and cathedrals produce infrasound this could lead to people having weird experiences which they attribute to God," said Professor Richard Wiseman, a psychologist from University of Hertfordshire.

"Some of the experiences in our audience included 'shivering on my wrist', 'an odd feeling in my stomach', 'increased heart rate', 'feeling very anxious', and 'a sudden memory of emotional loss'.

"This was an experiment done under controlled conditions and it shows infrasound does have an impact, and that has implications... in a religious context and some of the unusual experiences people may be having in certain churches." ...
