It’s easy to see why three-year-old aggressive and streaking behaviors would prompt a well-timed response in others (especially parents). Another common category of human behavior that elicits a behavioral response in others, in fact one of the most common, is expressive behavior. Human expressions are for other humans to see or hear or smell, precisely in order to prompt them to modulate their behavior. Sometimes another person’s response may be a complex whole-body behavior (I give my wife my come-hither look, she responds by going thither), and sometimes the other person’s behavioral response may simply be an expression of emotion (I grimace and rub my newly minted bruise, and my son responds by smiling). If music is good at getting us to move, then, in this light, one suspects that music must usually sound not merely like movement that kicks (literally, in my son’s case) listeners into moving in response, but, more specifically, like human emotional or expressive behaviors.

Sound triggering movement. That’s starting to sound a bit like dance. To more fully understand dance, we must grasp one further thing: contagious behaviors—behavioral expressions that tend to spread. For example, if I smile, you may smile back; and if I scowl, you’ll likely scowl back. Even yawns are catching. And contagious behavior is not confined to the face. Nervous behavior can spread, and angry bodily stances are likely to be reciprocated. If you raise your hands high into the air, a typical toddler will also do so, at which point you have a clear tickle shot. Even complex whole-body behaviors are contagious, accounting for why, for example, people in a crowd often remain passive bystanders when someone is being attacked (other people’s inaction spreads), and how a group of people can become a riotous mob (other people’s violent behavior spreads). By the way, have you yawned yet?

Music, then, may elicit movement for the same reasons that a cartoon smiley face can elicit smiles in us: music can often sound like contagious expressive human behavior and movement, and trigger a similar expressive movement in us. Music may not be marching orders from our commander, but it can sometimes cue our emotional system so precisely that we feel almost compelled to march in lockstep with music’s fictional mover. And this is true whether we are adults or toddlers. When music is effective at getting us to mimic the movement it mimics, we call it dance music, be it a Strauss waltz or a Grateful Dead flail.

The music-sounds-like-movement theory can, then, explain why music provokes us to dance—the third of the four hurdles a theory of music must leap over. The fourth and final hurdle concerns the structure of music, and it will take the upcoming chapter and the Encore chapter to make the case that music has the signature structure of humans moving.
