Ironically, the image and opening paragraphs, which 'sell' the story, go directly against the actual research. The theme to Jaws uses low bass sounds in piano, strings and brass with percussion interjections.
The sounds used in the research are high, screechy sounds made by a marmot in peril. The researcher, Daniel Blumstein, calls these "non-linear" sounds. I think I can sum up this study as follows: some animals make screechy sounds when terrified. Perhaps if similar sounds are inserted into films scores, they might stimulate fear arousal in the audience. For a laugh, go listen to the lame examples at the first link. Film composers come up with much better ways to write ominous, foreboding or scary music. As per the example from Jaws, composed by the ubiquitous John Williams.
Scientists, and, it seems, especially 'evolutionary biologists' seem to have absolutely no understanding whatsoever of music. But, armed with remarkably irrelevant research, they presume to tell us how music works. Give it a rest, guys. You haven't come up with one piece of research so far that hasn't made me laugh out loud.
