Looping and stasis in Medúlla

Malawey, Victoria. Harmonic Stasis and Oscillation in Björk’s Medúlla. Music Theory Online, Volume 16, Number 1, January 2010.

The fundamental unit of electronic popular music is the loop. This puts it at odds with the Western art music tradition, which typically favors linear structures with a narrative arc. Repetition has mostly appeared in classical music at the macro level of phrases and sections. While shorter repetitive cells do appear in classical music, they are not always welcome. The term ostinato, from the Italian “obstinate,” does not connote approval. Popular music (and some minimalist classical) of the twentieth century has been significantly more repetitive, deriving its harmony from western Europe but its rhythms and circular loop-based structures from Africa and the Caribbean. The advent of synthesizers, drum machines and computers has strongly encouraged the trend toward cyclic repetition, since the default output of such devices is the endless loop.

Björk produced relatively conventional dance music early in her solo career, but her use of loops has become more sophisticated and complex over the course of her career. Her 2004 album Medúlla is comprised entirely from vocals, aside from the occasional synthesizer. Some of the songs are traditional songs and choral works, but most are built from vocals that have been heavily edited, sampled and looped in Pro Tools.

Malawey’s article analyzes three songs from Medúlla in depth: “Öll Birtan,” “Who Is It” and “Triumph of a Heart.” Malawey is primarily interested in the circularity of these songs’ chord progressions. She explains their two-chord or one-chord structures as creating a sense of oscillation or stasis, rather than the source-path-destination schema of western classical tradition. While Björk’s harmonies are colorful, they are hardly groundbreaking. What makes Malawey’s analysis valuable for my purposes is that her vocabulary for harmonic analysis is also applicable to the sonic and emotional quality of looped samples.

“Öll Birtan” is built from layers of Björk’s voice singing highly repetitive figures on a single mixolydian scale. There is no beat per se, but there is an implicit pulse. The piece is less a pop song, and more an art piece reminiscent of Steve Reich. “Who Is It” and “Triumph of a Heart” are closer to dance music convention in form, but they use sampled beatboxing and mouth sounds in place of drum machines and breakbeats. Similarly, sampled vocal tones fill the role of basslines and keyboards. These videos use different mixes than the ones on the album, but they’re so delightful you should watch them anyway.

Malaway’s central thesis is that harmonic stasis creates a feeling of timelessness. She quotes Kofi Agawu:

Repetition enables and stabilizes; it facilitates adventure while guaranteeing, not the outcomes as such, but the meaningfulness of adventure. If repetition of a harmonic progression seventy-five times can keep listeners and dancers interested, then there is a power to repetition that suggests not mindlessness or a false sense of security (as some critics have proposed) but a fascination with grounded musical adventures. Repetition, in short, is the lifeblood of music.

Despite the fact that Agawu is dealing primarily with repetition in African music, much of what he says in this passage applies directly to all kinds of music that are based in repetitive processes. Furthermore, his quote explains the appeal of the more literal sonic repetition of looped samples.

When you listen to repetitive music, time is progressing in its usual linear way, but the cyclic sounds evoke timelessness and eternity. Malawey describes harmonic ostinatos as having a feeling of alternating repose and tension. I’ve found this to be true of looped samples as well; the first and third repetitions will have a “call” feeling that is “answered” by repetitions two and four. The continuing reversal of call and response, of front and back halves of a phrase, can evoke other image schemas as well. Malawey lists swinging, fluttering, quivering, jiggling, hovering and flickering as appropriate image schemas for repetitive music.

In other songs not discussed by Malawey, the feeling of stasis brought on by sampled vocals is even more prominent. The atmospheric haze that dominates “Desired Constellation” was created from a sample of Björk singing the phrase “I’m not sure what to do with it” from “Hidden Place” on her previous album, Vespertine. The vocal loop that opens “Mouth’s Cradle” is so severely processed as to be unrecognizable as a voice; it sounds more like a synthesizer sequenced using MIDI, and the bass notes are pitch-shifted to an unearthly depth. Together with the animalistic backing vocals forming the “percussion,” the collective effect is otherworldly.

Malawey does point out the connection between Björk’s radically simple chord progressions and her unearthly timbres. “[N]on-teleological harmonic processes make room for the vocal textures to carry the music forward.” By building a predictable musical foundation under her sonic experiments, Björk leaves the listener with enough attentional bandwidth to absorb the complexities of her vocal manipulation and looping. The familiarity of the voice combined with the “future shock” of radical digital editing challenges the listener, but the repetition makes the challenge a surmountable one, eventually leading to deep musical gratification.
