Manu Dibango released “Soul Makossa” in 1972. He wrote it as the B-side to “Mouvement Ewondo,” a praise song for the Cameroonian football team on the occasion of the 1972 Tropics Cup. Language Log explains the chant-like lyrics:

The story behind these seemingly nonsensical syllables is a fascinating one, originating in the Cameroonian language Duala.

Duala is spoken in Douala, Cameroon’s largest city, which has long been a musical hotbed. Since the 1960s, Cameroonian pop music has been dominated by a rhythmic style of dance music from Douala known as makossa. The Duala word makossa is often glossed as “(I) dance” (as in this article by Cameroonian linguist George Echu). The entry for makossa in the Oxford English Dictionary further explains that makossa is “derivative of kosa ‘to peel or remove the skin of (a fruit or vegetable)’; the name refers to the twisting and shaking movements of the dancer.”

Language Log quotes this excerpt of Dibango’s autobiography, Three Kilos of Coffee:

On one side of the 45 I recorded the hymn [praise song]; on the other I recorded “Soul Makossa,” written using a traditional makossa rhythm with a little soul thrown in. In my Douala neighborhood, at my parents’ house, I rehearsed this second piece. The house had no air-conditioning, and the windows were wide open. All the kids flocked around. Hearing me rehearse, they fell over laughing. Unbelievable — how on earth had I concocted that mishmash? Poor makossa really took a blow. My father was astonished: “Can’t you pronounce ‘makossa’ like everyone else? You stutter: ‘mamako mamasa.’ You think they’re going to accept that in Yaoundé?” The Cup organizing committee reacted the same way. The march on side one they found “impeccable.” But the other side… “Really, Manu has gone nuts. What possesses him to stutter like that?”

The New York DJ and party promoter David Mancuso got his hands on “Soul Makossa” and played it incessantly at his loft parties. The song became an underground hit, especially when it started getting airplay on WBLS. The few copies floating around New York were quickly snapped up by other DJs. Several bands rushed out their own covers to fill the gap, most notably Baba Olatunji and the Lafayette Afro-Rock Band. Their versions are fun, but nowhere near as funky as the original. Finally, Atlantic Records released Manu Dibango’s version on one of their sub-labels, and it went so far as to crack the top 40 in 1973.

Soul Makossa quotes, samples and remixes

Quoting “Soul Makossa” became something of a trope in the early eighties, ranging from subtle references to the beat or bassline or horn line to full-blown quotation. My favorite example is by Nairobi featuring the Awesome Foursome.

This song just screams 1982, especially with those 808 cowbells. This song was itself sampled in many other songs, including Schoolly D’s “Mama Feel Good.”

Kool Moe Dee’s “Pump Your Fist” draws on “Soul Makossa” for percussion, the wah guitar stab and part of the main sax riff.

A more recent example: “Latinhead” by Dirty Beatniks.

Soul Makossa has also been sampled by Jay-Z, Geto Boys, Poor Righteous Teachers and A Tribe Called Quest, among many others. See a full list of samples.

Michael Jackson and “Wanna Be Startin’ Something”

By far the most famous musical descendant of “Soul Makossa” is Michael Jackson’s first single from Thriller, the best song on that album and a strong contender for the best song of the eighties, period.

I was at a hippie-ish wedding this past summer. People were having a good time, but not really dancing. Then “Wanna Be Startin’ Something” came up on the iPod and the party suddenly jumped off. Little kids, old folks, everyone in between, people were getting down. Say what you want about Michael Jackson as a human being, but there’s no denying the power of this song. It never fails to get people shaking their butts, across all ages, races, classes and cultural backgrounds.

The copyright-minded among you might well ask: did MJ steal the Makossa chant? Manu Dibango certainly thought so, and sued MJ, eventually reaching an out-of-court settlement. The issue isn’t a cut-and-dried one for me, though. Here’s a side-by-side comparison of the two chants:

The most obvious difference is in the syllables, but there are musical differences too. Manu Dibango’s chant is a two-bar phrase sung/chanted entirely on the note G, over an unchanging G7 chord. Michael Jackson’s chant is a four-bar phrase with a call and response structure. He adds a two-note melody harmonized in thirds and a chord progression alternating between D/E and E7. MJ also uses a little more syncopation. I’d say that MJ’s chant is more of an adaptation than a direct theft.

“Wanna Be Startin’ Something” quotes, samples and remixes

Pop and hip-hop musicians quote MJ’s version of the Makossa chant incessantly. Some high-profile examples:

• “No Clause 28” by Boy George
• “Gettin’ Jiggy Wit It” by Will Smith
• “Cowboys” by the Fugees
• “Brooklyn Girls” by Charles Hamilton
• “Lost In The World” by Kanye West

People love to shout out the chant during live performances, too, everyone from Zap Mama to Jamie Foxx. Rihanna goes further than quoting MJ’s chant; she builds an entire dance track around a reharmonized sample of it. MJ’s song is in the key of E, but Rihanna’s producers put it in the key of F# minor. This is hip stuff; the same notes in MJ’s sunny and uplifting coda become melancholy in Rihanna’s track.

People quote other parts of “Wanna Be Startin’ Something” too. Big Daddy Kane quotes the “Yeah yeah” part in “Warm It Up Kane,” listen at 1:32.

Other tracks quoting this phrase include “Vibin’ (The New Flava Remix)” by Boyz II Men and Busta Rhymes featuring Treach, Craig Mack and Method Man, and “Feels So Good” by Mase.

Lord Tariq and Peter Gunz adapt big swaths of MJ’s song in “Startin’ Something.”

Björk has to be different, of course, so she (mis)quotes the opening line of MJ’s song in live versions of “I Go Humble.” And by the way, her MJ fandom was apparently reciprocal, if this radio show transcript is to be believed.

Visualizing the Makossa diaspora

Here’s a complete map of the genealogy of the Makossa chant; click to enlarge.

Putting it all together

Here’s a mashup I made combining several of the tracks mentioned above so you can get your makossa on.

Wanna Be Startin’ Something megamix by ethanhein

Any noteworthy sightings of the Makossa meme that I missed? Let me know in the comments.

Hat tip to Mike Devlin for coining the phrase “Makossa diaspora.”

I was only vaguely aware of Tribe back in the nineties. I knew them as the preferred hip-hop group for my white friends who were put off by the harder edges of Wu-Tang and the west coast gangsta rappers. I encountered “Scenario” and “I Left My Wallet In El Segundo” at parties, and found them entertaining, but didn’t feel compelled to go any deeper.

More recently, when I got into hip-hop scholarship in earnest, I started listening to Tribe for real. I downloaded “Check The Rhime” and was floored by the production.

The beats hit hard and simple; the samples are mysterious without being inaccessible; and the frenetic chorus contrasts excitingly with the buttery-smooth verses.

As I’ve been digging into more Tribe songs, I’ve been consistently impressed by their level of musicality. The tracks are accessible and fun, but on close scrutiny they’re dense with ambitious ideas. I’m particularly fond of the six-bar loop in “Electric Relaxation.”

Anyone can use an unusual phrase length, but it takes real artistry to make it sound so smooth and natural.

As for the movie itself, I enjoyed it and learned a lot. Some longtime Tribe fans of my acquaintance complain that it focuses too much on the present and doesn’t spend enough time on Tribe’s prime back in the 90s. That’s a fair point, and I certainly wouldn’t mind having more context on hip-hop’s golden age. But I thought the movie did a great job digging into the complicated relationship between the members of Tribe. I agree with Rob Fields’ review:

By far the most moving core of the film is the peek that it offers inside the relationship between Jarobi and Phife. It’s rare to see examples on the screen of two black men who have such unconditional love for each other.

The movie confirms that Q-Tip is central force behind Tribe, both on the production side and in setting the overall tone. But the other guys must have brought something to the table, even if it was just peer pressure. Tip’s post-Tribe music has been, you know, fine, but there hasn’t been anything remotely like “Check The Rhime.” When he calls himself “the Abstract,” Tip isn’t kidding. Phife and the others seem to have kept Tip’s ideas more down to earth, which helped make them stronger. The conflict between Tip and Phife is as much a part of their story as their creative partnership. Here’s an interview with director Michael Rapaport if you want some background.

One of the high points in the movie is Tip talking about his late father. He talks about getting the beat for “Can I Kick It” from a Dr Lonnie Smith record that he associated with his dad.

I’ve heard other hip-hop artists talk about sampling their parents’ music as a way of connecting to the older generation while still forging a new sound with present-day relevance. I know a lot of lame instrument-playing musicians who imitate the music of their parents out of an anxiety that they might deviate too far from what’s musically acceptable. Taking samples and transforming them makes for a healthier relationship to your ancestors.

Speaking of samples, I heard “Bonita Applebaum” for the first time in the movie.

I was delighted to discover the source of the sitar sample in the Fugees’ version of “Killing Me Softly.” And where did Tribe get that sitar from in the first place? A totally ridiculous song by Rotary Connection called “Memory Band.”

The real art of sampling isn’t just finding some great song and repeating the hook; it’s finding a hook in a terrible song and using it to build a new great song. But here’s the crazy thing. The main groove under the verses in “Check The Rhime” comes from “Baby, This Love I Have” by Minnie Riperton. Guess who the female singer in Rotary Connection was?

Q-tip seems like the exact kind of crate-digging sample geek who would know about the Minnie Riperton connection. A man after my own heart.

The film was also my first exposure to the concept of the pause tape, which is how a lot of hip-hop producers got started back in the day. Before digital samplers became so cheap and accessible, pause tapes were the easiest way to create loops. You’d put your tape recorder on pause and cue up the record to just before the part you wanted to sample. When the downbeat of the sample started, you unpaused the tape, and paused it again when the sample ended. Then you cued the record back up to the same spot, and repeated, and repeated, and repeated. Here’s a video of the process.

Tribe’s influence on present-day music can be felt in unexpected ways. Check out this remix of “I Left My Wallet In El Segundo” around the 0:35 mark.

That little phrase, slowed way down, became the basis for “A Milli” by Lil Wayne. Hear the process at work.

I hope this movie inspires more movies about golden-age hip-hop, and I hope they continue to dig into the nuts and bolts of the creative process. People hear so much hip-hop but know so little about where it comes from, what it means, what the connections are. That ignorance extends to many of the musicians I know. Keep the documentaries coming!

Now that mashups are so common, this track doesn’t sound particularly remarkable. But in seventh grade it was startling to hear a house music track full of random samples. “Pump Up The Volume” was part of the same UK dance music movement that spawned the KLF’s “Doctorin’ The Tardis” and “Rush” by Big Audio Dynamite. I wasn’t enough of a hip-hop head in 1987 to recognize where the phrase in the title comes from, but now I do, it’s from “I Know You Got Soul” by Eric B and Rakim. Listen at 0:43:

It makes sense that I first encountered Rakim Allah in the context of a sample, because he and Eric B pretty much wrote the book on sample-based music. “I Know You Got Soul” is named for the Bobby Byrd song, written and produced by James Brown, that you hear looped throughout the track. Sampling James Brown has become a basic part of the musical toolkit, but it wasn’t such an obvious choice back in 1987. Stetsasonic said it best in their song “Talkin’ All That Jazz:”

Tell the truth, James Brown was old
’til Eric and Ra came out with “I Got Soul.”

Now, thanks to eighties hip-hop, James Brown will be cool forever. Sample-based music is supposed to be “fake,” but paradoxically, sampling made funk authentic again after disco had turned it corny. Michael Krimper observes in his blog post Future Funk: Searching For The Lost Groove that by removing music from its original social context, sampling frees it to be heard and experienced in new and unexpected ways.

The aesthetics of the hip-hop beat — one of recycled recorded sounds and reinvented roles for samples clips repeated on loop — spawned a whole new social practice of archiving. A new culture of crate diggers, both collectors and enthusiasts, grew obsessed with finding and archiving dusty, lost vinyl from a previous generation… It’s almost as if these producers began, nearly 20 years later, where the previous musicians had left off. Those funk sounds, once dulled down by over-saturated commercial mediation, became fresh again and pregnant with a wave of creative potential. The early hip-hop generation didn’t grow up during the golden age of the funk era, but they listened and absorbed at home as children. They grew familiar with the sounds without enduring the same forces of marketing as their parents. Maybe that opened up enough free space for them to imagine the music differently.

Eric and Ra have a futuristic electronic sound based almost entirely on samples and turntable scratching, but its futurism is balanced by the rich network of associations they build in with their choice of sampled records. Here’s a map of all the samples on the album Paid In Full – click to see it bigger:

Fittingly, Eric B and Rakim have themselves been a rich source of samples for other artists, starting with Coldcut’s epic remix of “Paid In Full.” Eric and Ra themselves have sampled the songs on Paid In Full many times as well. The phrase “follow the leader” at 1:03 in “I Know You Got Soul” is the basis for, you guessed it, “Follow The Leader.”

Eric and Ra sample “Eric B Is President” in both “Eric B Never Scared” and “Move The Crowd.” This kind of extreme self-reference has been an inspiration for subsequent self-samplers, like Nas on “Nas Is Like” and Fugees on “The Score.” And by the way, “The Score” includes a sample of Eric and Ra’s “My Melody,” which heavily features a sample of itself. How’s that for recursion?

Eric and Ra also inspired the recording of mine that I’m most proud of. “Eric B Never Scared” samples “Those Shoes” by the Eagles. When it came time for my band Revival Revival to work up our arrangement of “Those Shoes” it seemed logical to work in a sample of “Eric B Never Scared.” This is easily the nastiest groove I’ve ever put together.

Revival Revival – Those Shoes Never Scared by ethanhein
I had a teenage guitar student who loves hip-hop, and he asked me for some recommendations. He was underwhelmed when I played him “Follow The Leader” — he thought it sounded old-fashioned and unsophisticated. I was shocked; what could be fresher than Eric B and Rakim? But I’m from a different generation. High school kids now were born into a world where hip-hop is a given. They take it for granted that artists like OutKast and Common and Lauryn Hill will pack their flows with dense internal rhymes and tumbling streams of imagery. Rakim doesn’t sound so groundbreaking now that every halfway decent emcee has absorbed his techniques. It’s like the way the radical innovations of Jimi Hendrix have been turned into standard rock cliches. It takes some historical context to imagine how stunning he must have been back in the sixties.

Rakim came by his connection to the musical past more personally than most, since he’s the nephew of the great R&B singer Ruth Brown. In an interview with Planet Ill, he talks about how his musical upbringing impacted his flow:

I think playing in the bands and learning how to read music; learning the theory of music breaks it down a little more and you get to understand it better. It helped me a lot with my rhythms and my syncopations… I played the sax in school. I play alto all the way up to baritone sax. Coming up in the house my older brother played piano, my middle brother older than me played saxophone, the drums.  I tried to get my hands on whatever I could.

You can clearly hear the bebop in Rakim’s deadpan delivery and his long chains of eighth notes, starting and ending on unexpected beats. His flat affect holds a lot more swagger than if he was yelling and screaming. It lets you focus on the complex musicality of the words. For the first couple of albums, he uses every single song to rap about how awesome he is at rapping, which he proves by being awesome at rapping, even when he’s just rapping about how awesome he is at rapping.

I’m a member of the first hip-hop-listening generation and I still hear Eric and Ra as hot. All that minimalism and repetition and empty space — I know plenty of musicians who are still catching up with it. The eighties hip-hop sound feels urgent to me, it’s so confident in itself. It becomes timeless by being so unapologetically of its time.

Some of the musicians I work with are very anxious about not being too fresh. There’s this need to imitate the masters of the past, to not stray too far from the territory marked out by the Beatles or Led Zeppelin or John Coltrane or whoever their idols may be. This results in weak music. How can you tell the truth about yourself when you’re too timid to belong to your own time and place? I want to grab any musician now who’s obsessed with sounding like Zeppelin, and ask: would you care about them if they were anxiously imitating the music of thirty or forty years before them? There were plenty of bands in 1975 who only played big band jazz, does anyone care about them now? Led Zeppelin took big risks in 1975. Now that their sound has become acceptable, there’s no risk in sounding like them, and no reward either. It’s 2010, better to play and write and produce like it’s 2010.

That doesn’t mean you have to forget or ignore the past. Far from it. Best to follow Eric and Ra’s example and study the past, incorporate it and transform it. The Biz Markie sampling lawsuit may have thrown a wet blanket onto sample-dense music as a commercial enterprise, but the artistic genie is out of the bottle. I, for one, plan to keep doing as much sampling as I can get away with.

Meanwhile, Eric and Ra continue to make their presence felt. The list of hip-hop and techno artists who sample or quote them is too long to go into, and it runs right up to the present. They’ve even crossed over into video game territory — DJ Hero lets you mash them up with MIA, Tears For Fears and David Axelrod.

Hear my mashup of “I Know You Got Soul” with “Pump Up The Volume” and “Follow The Leader.”

I Know You Got Soul Megamix by ethanhein

Glenn Gould wasn’t necessarily being prophetic. He was just paying attention to the long history of music before the relative eyeblink of the twentieth century. The always perspicacious Wayne Marshall says:

Only in the relatively recent past — within the last century — have songs, in the “fixed” media form of audio recordings, been so strongly regulated as pieces of property whose use by others might be strictly limited. An examination at the level of cultural practice — that is, how songs as audio recordings have been used by people — demonstrates that even in such “fixed” form, songs have continued to serve as a commonplace site of sharing and creative interaction (also known as remixing). This becomes particularly evident in the use of playback technologies such as turntables as creative instruments in their own right (aiding the emergence of hip-hop and disco in the 1970s), an approach powerfully extended by the tools of the digital age.

I’m a child of the cassette era. I loved making mix tapes in high school, for myself and whoever among my friends would listen. It was a pain, but still worth it. I still remember burning my first CD, sequencing the tracks with Toast before the half-hour long burn session during which the computer couldn’t do anything else. I’ve said farewell to albums with little sadness. It’s nice to listen to Graceland or Abbey Road in their original sequence, but for the most part, I do a better job of sequencing tracks for my own needs than anyone else can.

What’s true at the multiple-song level is even more true within a single song. Writing a song is really sequencing together a “mixtape” of licks, scale fragments, chord progressions and beats. When I learned how to play the guitar, I became free to string together whatever song fragments I could get under my fingers. It was fun being able to freely collage songs together, constructing segues and suites. All “new” compositions are really mashups you make in your head. Any creative undertaking is less like conjuring out of thin air and more like making a salad. As a sampler and remixer, my freedom of musical choice is total. Making mashups is a delightful blend of writing songs and putting together mixtapes, except that the pieces of music are shorter and layered simultaneously.

Mashup and remix culture isn’t new. Club DJs have been mashing up songs on the fly for decades, intermixing hot dance tracks with hooks and breaks from other well-known dance tracks. Girl Talk has nothing on “The Adventures Of Grandmaster Flash On The Wheels Of Steel” or Double Dee and Steinski’s “Lesson” mixes. Creating popular music is a ruthless evolutionary process. You sort through idea after idea, looking for the hooks. The best mashups take the Darwinian process to the next level, mating the hooks together into ultrahooks. My favorite mashups of the moment are the United State Of Pop mixes by DJ Earworm. He takes the top twenty-five singles from a given year and boils them down into single, devastating tracks.

United State Of Pop 2007

United State Of Pop 2008

There are plenty of other high-concept mashups like these, and some of them work as music, but a lot of them are gimmicky and annoying. In order to work, there has to be some musical resonance between the source tracks. The more unexpected the affinity, the better. My favorite Earworm mashup combines Django Reinhardt’s performance of “Brazil” with Paul Simon’s “Diamonds On The Soles Of Her Shoes.”

Brazilian Diamonds

Who would have guessed that the bouncy rhythms of South African pop as filtered through the mind of a Jewish folksinger from Queens would mesh so well with the bouncy rhythms of samba as filtered through the mind of a Belgian gypsy jazz guitarist? This kind of discovery is only possible via a lot of trial and error. The growing ease and plummeting price of audio editing makes trial and error a lot less onerous than it used to be.

One of the great pleasures of sample-based music is encountering something familiar in a strange context. Sometimes the recontextualization can be jokey, like Ludacris’ ironically grandiose “Coming 2 America” which combines quotes from the Eddie Murphy movie with themes from both Mozartâ’s Requiem and the last movement of Dvorak’s New World symphony. Sometimes it’s playful without being jokey. Mozart’s “Queen of the Night” aria from his opera The Magic Flute shows up in “Like You” by Kelis, and it makes me wonder why every R&B song doesn’t include coloratura soprano.

The mixtape-mashup analogy isn’t perfect. Mixtapes are linear, with each song usually appearing once. If you make a mashup in this linear way, with each sample appearing only once, it will probably be annoying. Within the parameters of a song, repetition is crucial to enjoyment. This is why Girl Talk gets on my nerves. He runs a sample four or eight times and then forgets about it. His tracks are too much like watching someone else flip channels on TV for my tastes.

I’m especially interested in musicians who use samples of themselves as the basis of new works. The first Nas song I heard was his biggest hit, “Nas Is Like.” The chorus is based on samples of his earlier song “It Ain’t Hard To Tell.” When I heard the original, it sounded like it’s full of samples of “Nas Is Like.” This confusion of time sequence is one of the central pleasures of sample-based music for me. The meta-recursive hip-hop prize probably belongs to the Fugees, whose song “The Score” includes samples of every other song on the album of the same name.

The mashup doesn’t belong exclusively to music. The video mashup is coming excitingly into its own. I would have expected that combining two songs in 5/4 time might be too clever, but in this case it works:

The video mashup’s answer to DJ Earworm is Kutiman, who stitches together multiple Youtube videos. Check out “The Mother Of All Funk Chords”:

Jonathan Lethem’s essay on literary mashup culture, “The Ecstasy Of Influence,” is itself an amazing literary mashup. There are visual mashups too, I have a collection of them on Flickr. An intriguing random visual mashup maker is the Ad Generator. Its makers explain: “Words and semantic structures from real corporate slogans are remixed and randomized to generate invented slogans. These slogans are then paired with related images from Flickr, thereby generating fake advertisements on the fly.” It works uncannily well.

The fan-made advertising mashup shows the potential to become an entire new artistic style unto itself. Dig this trailer for an as-yet nonexistent Green Lantern movie made entirely out of pieces of other movie trailers:

Sasha Frere-Jones says in his essay 1 + 1 + 1 = 1:

See mashups as piracy if you insist, but it is more useful, viewing them through the lens of the market, to see them as an expression of consumer dissatisfaction. Armed with free time and the right software, people are rifling through the lesser songs of pop music and, in frustration, choosing to make some of them as good as the great ones.

This very blog post is a mashup of Glenn Gould and Wayne Marshall and DJ Earworm and Grandmaster Flash and Kutiman and uncountable others. I know there are plenty of copyright holders out there that regard any kind of derivative work as stealing. I think it’s a misplaced form of anxiety. I think mashups are natural, healthy, and the best vector to get your ideas circulating through the memepool long after you’re gone. As I was writing this post, I discovered someone did a version of my Michael Jackson sample map with Michael Jackson on it, and I couldn’t be more flattered.

Long live DJ culture, across whatever media!

Self-reference and looping in computer programs

When I was in fifth grade, we did some programming on Apple IIe computers using Sprite Logo, a student-friendly version of the venerable programming language Lisp. In Sprite Logo, you write commands that move a cartoon turtle around the screen (back in the eighties, it was more just an abstract triangle.) The turtle has a pen attached to its tail, and by specifying its path around the screen, you can make it draw shapes. By default, the turtle begins in the center of the screen, pointed up. Here’s how you tell the turtle to draw a box one hundred pixels on a side, in Logo-like pseudocode:

go forward 100 pixels
turn left 90 degrees
go forward 100 pixels
turn left 90 degrees
go forward 100 pixels
turn left 90 degrees
go forward 100 pixels
end

Here’s how you make the turtle draw an equilateral triangle:

go forward 100 pixels
turn right 120 degrees
go forward 100 pixels
turn right 120 degrees
go forward 100 pixels
end

You can tell Sprite Logo to repeat parts of the program by having it repeat parts of itself, using notation very similar to repeat markers in music. You might draw your square by defining a procedure to draw a single side, and then tell the program to repeat this procedure four times:

repeat 4 times: (go forward 100 pixels, turn left 90 degrees)
end

Here’s how you’d draw the triangle using repeats:

repeat 3 times: (go forward 100 pixels, turn right 120 degrees)
end

You could draw five triangles spaced two hundred pixels apart like so:

repeat 5 times: (repeat 3 times: (go forward 100 pixels, turn right 120 degrees)), go forward 200 pixels)
end

A more modern way to draw five triangles is to create procedures called “square side” and “triangle side,” and then have the program run them a certain number of times:

define 'triangle side' as (go forward 100 pixels, turn right 120 degrees)
define 'triangle' as (repeat 3 ('triangle side'))
repeat 5 ('triangle', go forward 200 pixels)
end

This kind of nested self-reference is so common in computer programming that it’s easy to forget how weird it is. Computer programs use the same code for both programs and the data that the programs are acting on. In other words, programs can use themselves as data. They can take their own code as input, and can output code too. You can nest layers of self-reference within self-reference in your programs to whatever depth you want. Such self-referential nesting is considered good programming technique, and most of the software we use every day is full of it.

Self-reference and looping in music

Music is full of self-referential loops. No form of music is more self-referential than hip-hop. In “My Melody” by Eric B and Rakim, Eric B takes the line “Check out my melody” and re-sequences its DNA, live on tape, using a sample of the song itself:

Ch-ch-ch-ch-check out, check out check out my melody.
Ch-ch-ch-ch-check out, check out check out my melody.

Digital audio supports effortless and endless recursion. You lose a little signal quality duing the encoding process, but once you have your list of ones and zeros, you can copy it flawlessly across any different medium, as many times as you you want. It’s not uncommon for DJs and producers to heavily sample themselves, or their own projects, and it’s not uncommon to use samples of samples of samples.

Any song that samples the ubiquitous “Funky Drummer” remix is already a remix of a remix. This is before we come to the uncountable thousands of samples of tracks based on samples of the remix, or samples of those tracks.

A particularly remarkable knot of self-reference is “The Score” by The Fugees, from their album of the same name.

“The Score” is based on samples of “My Melody,” “Dove” by Cymande and “Planet Rock” by Afrika Bambaataa, itself based on interlocking excerpts of other tracks. “The Score” also includes samples from every other song on the album “The Score”, and those songs mostly contain samples of still other songs:

Douglas Hofstadter thinks that self-reference is the key to consciousness. That could explain why it’s such a source of fascination for me: I’m seeing a reflection of myself.
