New research has found that some people may have a natural ability to distinguish between musical notes.
The babies had to decide which side to look when they heard a sound, and a picture would appear on either the right or left depending on whether it was a major or minor tone scramble. “If they can tell the difference in the tone, over time, when they hear the major notes for example, they’ll make an eye movement to the location for the picture even before the picture appears because they can predict this. This is what we are measuring,” says researcher Scott Adler.
