Brown on the blues

He鈥檚 at it again. After setting the world on fire with his groundbreaking research that deconstructed the opening chord to The Beatles鈥 A Hard Days Night, Jason Brown is now out to apply mathematical principles to determine what makes the blues鈥ell, the blues.

In the May edition of the Canadian Mathematical Society鈥檚 journal, CMS Notes, the 麻豆传媒 math professor has published an article 鈥 鈥淒educing the Blues鈥 鈥 that seeks to analyze the blues progression, said to be the 鈥渕ost famous chord progression in modern music.鈥

The significance of this progression is singularly important to the genesis of rock 'n' roll. Dr. Brown cites numerous classic rock songs that owe their structure and their universal appeal to this progression 鈥 Johnny B. Goode, Hound Dog, Rock Around the Clock, Long Tall Sally, Kansas City and聽hundreds more we all know and love 鈥 and looks at a common blues chord progression that links them all together. He suggests the harmonic sequence is 鈥減erfect鈥 and compares the experience of listening to the progression to a roller coaster.

鈥淭he blues chord progression has been used in other genres, such as country music and jazz, perhaps indeed precisely for the thrill it can add to the harmonic underpinning of the songs,鈥 he notes. 鈥淭he research points towards how you might have the pace of any given chord progression ebb and flow to create and release tension along the harmonic path.鈥

Dr. Brown鈥檚 鈥渞oller coaster鈥 concept uses the notion of the excitement one might feel on the amusement park ride: up and down, peak to valley and to peak again. The experience is one of tension and release. He applies the same idea to music, constructing a model that uses twelve bars following a sequence that assigns the most 鈥渆xciting鈥 chords to key places in the sequence, with the biggest 鈥渃limb鈥 at the beginning of the end of the song.

So why the blues? Couldn鈥檛 we apply the same formula to other kinds of music? As it turns out, the blues lends itself to this kind of mathematical modeling in a way other musical genres do not. 鈥淐ountry music has no one fixed chord sequence that permeates its tunes, and jazz has even a greater variety of chord progressions for its songs,鈥 Dr. Brown points out. 鈥淚t is the fixation of blues on essentially one famous chord progression that makes it amenable to mathematical study.鈥

And what would he say to those who might question the notion of trying to demystify a genre of music that perhaps should remain somewhat mysterious, something that should be more about the heart than the head? 鈥淭he heart and brain are not independent 鈥 deep emotions can be stirred by the beauty inherent in the underlying mathematics,鈥 he suggests. 鈥淲hile there are undoubtedly some great blues solos that defy explanation, mathematical principles can explain why we are so moved by blues聽鈥 why it is indeed so external, so right.鈥

So what鈥檚 the next great musical mystery Dr. Brown will take on? Finally deciphering exactly what the heck the Kingsmen鈥檚 Louie Louie is actually about? Establishing the definitive link between the main riff to The Kinks鈥 You Really Got Me and modern-day heavy metal? Figuring out the exact point at which Britney Spears鈥 actual voice gives way to the computerized AutoTune program? He鈥檚 not ready to be specific but the musical/math collective journey continues.

鈥淚 continue to seek a further understanding of the process of writing music, and the connections between mathematics and the aesthetics of music,鈥 he says. 鈥淭he border where the creative, emotional and analytical aspects of great songs meet is one that I want to continue to explore.鈥
