Music and math are highly intertwined. By understanding beat, rhythm, and scales, children are learning how to divide, create fractions, and recognize patterns. It seems that music wires a child's brain to help him better understand other areas of math, says Lynn Kleiner, founder of Music Rhapsody in Redondo Beach, CA. As kids get older, they'll start reciting songs, calling on their short-term memory and eventually their long-term memory. Using a mnemonic device to do this is a method that can later be applied to other memory skills, says Mary Larew, Suzuki violin teacher at the Neighborhood Music School in New Haven, Connecticut. Musical instrument classes also introduce young children to basic physics. For instance, plucking the strings on a guitar or violin teaches children about harmonic and sympathetic vibrations. Even non-string instruments, such as drums and the vibraphone, give big kids the opportunity to explore these scientific principles.
