Beats and Grooves: The Engine Room of Music

Tap your finger on your desk at a steady, even pace. Keep going. That tap — regular, unwavering — is what musicians call the beat. Now think about a song you love. Is it easy to nod your head or tap your foot to it? If so, something in that music is locking on to that steady pulse and doing something interesting with it. Here is the puzzle: two songs can share exactly the same tempo (speed) and yet one makes you want to move while the other leaves you cold. Why? That difference is almost entirely about groove — and groove lives in the relationship between the beat and the rhythms layered on top of it.
