While listening to music, you might find yourself tapping your foot or bobbing your heads

to the beat. What you might not have expected is that as you listen to your favorite tune,

the rhythms in your brain also follow along. Brain rhythms arise when large groups of neurons fire together. Previous

studies have shown that listening to someone talk can elicit such activity. Now, research reveals

that brain rhythms also synchronized with musical sequences, and musical training

can enhance this ability. The study is in the proceedings of the National Academy of Sciences.

Magnetoencephalography, or MEG, is a technique that measures the tiny magnetic fields generated by

brain activity. Researchers used MEG to compare the brains and musicians

and non-musicians while the subjects tried to detect small changes in pitch during short clips of classical piano music by composers like Bach, Beethoven, and Brahms.

The train musicians, not surprisingly, track the pitch changes better.

When it came to tempo, musicians and non-musicians alike, sink their brains to the music,

when the music had more than one note per second.

But when faced with slower tempos, only the brains a musician synced up.

Because speech and music share similar brain networks,
