　　While listening to music, you might find yourselftapping your foot or bobbing your head to the beat.

　　What you might not have expected is that as youlisten to your favorite tune, the rhythms in yourbrain also follow along.

　　Brain rhythms arise when large groups of neuronsfire together.

　　Previous studies have shown that listening to someone talk can elicit such activity.

　　Now research reveals that brain rhythms also synchronize with musical sequences.

　　And musical training can enhance this ability.

　　The study is in the Proceedings of the National Academy of Sciences.

　　Magnetoencelphalography, or MEG, is a technique that measures the tiny magnetic fieldsgenerated by brain activity.

　　Researchers used MEG to compare the brains of musicians and non-musicians while thesubjects tried to detect small changes in pitch during short clips of classical piano music bycomposers like Bach, Beethoven and Brahms.

　　The trained musicians, not surprisingly, tracked the pitch changes better.

　　When it came to tempo, musicans and nonmusicians alike synched their brains to the music—when the music had more than one note per second.

　　But when faced with slower tempos, only the brains of musicians synched up.

　　Because speech and music share similar brain networks, it's possible that musical training thuscould also improve linguistic abilities.

　　So pick up your instrument of choice and play away you might not feel it, but your brainwaveswill dance along to your favorite song.
