“Singing—much like rhyming—is a special form of language that improves children’s memory, and teaches them rhythm and melody. Brain research has shown that when children are sung to, both the left and right sides of their brains are activated, strengthening their neural connections. Singing can also teach children new vocabulary words.
“But children don’t get the same benefits from listening to a CD or musical video. According to Sally Goddard Blythe, director of the Institute for Neuro-Physiological Psychology, the benefits to brain development occurs best when a parent or caregiver sings directly to, and with, a young child.”
