Read an interesting article on MSNBC about newborns’ ability to follow a rhythm. “Infants as young as 2 days old can process pitch and tell if a series of notes are rising or falling in scale. And it is now known they have rhythm, too.”. A study last year found that babies as young as 5 months can distinguish an upbeat tune, such as “Ode to Joy” from Beethoven’s Ninth Symphony, from other gloomy tunes.
