A study done in the United Kingdom concluded that children are able to recognize and even prefer music that they had heard while in the womb up to three months before birth. Although the genera of music made no difference, the babies who were exposed to songs with a faster tempo showed a stronger preference for that song than those who had heard something slower. (”Babies Remember Music Heard in the Womb”) Researchers have also found that the playing of soft background music or a mother’s humming actually helps premature babies. Those who are subjected to the music tend to gain weight faster and are able to leave hospitals earlier than those who aren’t. (Cromie, “Music on the Brain”)
