Evolution of music by public choice

Music evolves as composers, performers, and consumers favor some musical variants over others. To investigate the role of consumer selection, we constructed a Darwinian music engine consisting of a population of short audio loops that sexually reproduce and mutate. This population evolved for 2,513 generations under the selective influence of 6,931 consumers who rated the loops’ aesthetic qualities. We found that the loops quickly evolved into music attributable, in part, to the evolution of aesthetically pleasing chords and rhythms. Later, however, evolution slowed. Applying the Price equation, a general description of evolutionary processes, we found that this stasis was mostly attributable to a decrease in the fidelity of transmission. Our experiment shows how cultural dynamics can be explained in terms of competing evolutionary forces

Facing the Music

Hemingway had rock-star status (and even impersonators). Steinbeck was Springsteen. Salinger was Kurt Cobain. Dorothy Parker was Courtney Love. James Jones was David Crosby. Mailer was Eminem. This is to say -- and I understand how hard this is to appreciate -- that novelists were iconic for much of the first half of the last century. They set the cultural agenda. They made lots of money. They lived large (and self-medicated). They were the generational voice. For a long time, anybody with any creative ambition wanted to write the Great American Novel.
But starting in the fifties, and then gaining incredible force in the sixties, rock-and-roll performers eclipsed authors as cultural stars. Rock and roll took over fiction's job as the chronicler and romanticizer of American life (that rock and roll became much bigger than fiction relates, I'd argue, more to scalability and distribution than to relative influence), and the music business replaced the book business as the engine of popularculture.
Now, though, another reversal, of similar commercial and metaphysical magnitude, is taking place. Not, of course, that the book business is becoming rock and roll, but that the music industry is becoming, in size andprofit margins and stature, the book business.
In other words, there'll still be big hits (Celine Dion is Stephen King), but even if you're fairly high up on the music-business ladder, most of your time, which you'd previously spent with megastars, will be spent with mid-list stuff. Where before you'd be happy only at gold and platinum levels, soon you'll be grateful if you have a release that sells 30,000 or 40,000 units -- that will be your bread and butter. You'll sweat every sale and dollar. Other aspects of the business will also contract -- most of the perks and largesse and extravagance will dry up completely. The glamour, the influence, the youth, the hipness, the hookers, the drugs -- gone. Instead, it will be a low-margin, consolidated, quaintly anachronistic business, catering to an aging clientele, without much impact on an otherwise thriving culture awash in music that only incidentally will come from the music industry.
This glum (if also quite funny) fate is surely the result of compounded management errors -- the know-nothingness and foolishness and acting-out that, for instance, just recently resulted in what seems to be the final death of Napster.
But it's way larger, too. Management solutions in the music business have, rightly, given way to a pure, no-exit kind of fatalism.
It's all pain. It's all breakdown. Music-business people, heretofore among the most self-satisfied and self-absorbed people of the age, are suddenly interesting, informed, even ennobled, as they become fully engaged in the subject of their own demise. Producers, musicians, marketing people, agents. . . they'll talk you through what's happened to their business -- it's part B-school case study and part Pilgrim's Progress.

Music to our ears

The study reveals that as people age, they may experience changes in their brains that compromise hearing and that may impair a person's ability to interpret speech.
The researchers note that other studies have shown that these changes are not an inevitable effect of aging, as studies of musicians suggest that lifelong musical training may delay or offset such cognitive declines.
For the study, the participants listened to synthesized speech syllables while the researchers measured activity in the auditory brainstem.
The researchers discovered that, despite not having having played an instrument in nearly 40 years, the participants who completed 4-14 years of music training early in life had the fastest response to the speech sound (approximately a millisecond faster than those without music training).
And while a milliseconnd may not sound that impressive, its effects may be accumulative. Prof. Michael Kigard, who studies how the brain processes sound at the University of Texas at Dallas, and who was not involved in the study, explains:
"Being a millisecond faster may not seem like much, but the brain is very sensitive to timing and a millisecond compounded over millions of neurons can make a real difference in the lives of older adults,"
The Northwestern University team found that the more years study participants spent playing instruments as youths, the faster their brains responded to a speech sound.

Is Music the Key to Success?

Multiple studies link music study to academic achievement. But what is it about serious music training that seems to correlate with outsize success in other fields?
The connection isn’t a coincidence. I know because I asked. I put the question to top-flight professionals in industries from tech to finance to media, all of whom had serious (if often little-known) past lives as musicians. Almost all made a connection between their music training and their professional achievements.
The phenomenon extends beyond the math-music association. Strikingly, many high achievers told me music opened up the pathways to creative thinking. And their experiences suggest that music training sharpens other qualities: Collaboration. The ability to listen. A way of thinking that weaves together disparate ideas. The power to focus on the present and the future simultaneously.
Will your school music program turn your kid into a Paul Allen, the billionaire co-founder of Microsoft (guitar)? Or a Woody Allen (clarinet)? Probably not. These are singular achievers. But the way these and other visionaries I spoke to process music is intriguing. As is the way many of them apply music’s lessons of focus and discipline into new ways of thinking and communicating — even problem solving.
Look carefully and you’ll find musicians at the top of almost any industry. Woody Allen performs weekly with a jazz band. The television broadcaster Paula Zahn (cello) and the NBC chief White House correspondent Chuck Todd (French horn) attended college on music scholarships; NBC’s Andrea Mitchell trained to become a professional violinist. Both Microsoft’s Mr. Allen and the venture capitalist Roger McNamee have rock bands. Larry Page, a co-founder of Google, played saxophone in high school. Steven Spielberg is a clarinetist and son of a pianist. The former World Bank president James D. Wolfensohn has played cello at Carnegie Hall.
“It’s not a coincidence,” says Mr. Greenspan, who gave up jazz clarinet but still dabbles at the baby grand in his living room. “I can tell you as a statistician, the probability that that is mere chance is extremely small.” The cautious former Fed chief adds, “That’s all that you can judge about the facts. The crucial question is: why does that connection exist?”
Paul Allen offers an answer. He says music “reinforces your confidence in the ability to create.” Mr. Allen began playing the violin at age 7 and switched to the guitar as a teenager. Even in the early days of Microsoft, he would pick up his guitar at the end of marathon days of programming. The music was the emotional analog to his day job, with each channeling a different type of creative impulse. In both, he says, “something is pushing you to look beyond what currently exists and express yourself in a new way.”
Mr. Todd says there is a connection between years of practice and competition and what he calls the “drive for perfection.” The veteran advertising executive Steve Hayden credits his background as a cellist for his most famous work, the Apple “1984” commercial depicting rebellion against a dictator. “I was thinking of Stravinsky when I came up with that idea,” he says. He adds that his cello performance background helps him work collaboratively: “Ensemble playing trains you, quite literally, to play well with others, to know when to solo and when to follow.”
For many of the high achievers I spoke with, music functions as a “hidden language,” as Mr. Wolfensohn calls it, one that enhances the ability to connect disparate or even contradictory ideas. When he ran the World Bank, Mr. Wolfensohn traveled to more than 100 countries, often taking in local performances (and occasionally joining in on a borrowed cello), which helped him understand “the culture of people, as distinct from their balance sheet.”
