Ignoring Noise

Jonathan L. Friedmann, Ph.D.

As a rule, musical sounds are more clearly distinguished from non-musical sounds (the sounds of “reality”) than visual arts are distinguished from the shapes and colors of the visible world. What makes a photograph, abstract painting, or found object distinct from non-art is more difficult to pinpoint than what makes music sound like music. Satirist Ambrose Bierce addressed this in The Devil’s Dictionary, which defines painting as “The art of protecting flat surfaces from the weather and exposing them to the critic.” The viewing venue, in other words, plays a central role in the creation and perception of visual arts. (Marcel Duchamp’s Fountain, a porcelain urinal signed “R. Mutt,” is an extreme example.) Contrastingly, music is invisible, and thus cannot be confused with visible forms; it has no direct analog in the physical world.

Music is a culturally defined sonic phenomenon that, while impossible to define universally, is immediately recognized when heard in its cultural setting. Historically in the West, this has included a division between “pure” tones and “disordered” or “unwanted” sounds, generally called “noise.” Physics seems to support this bifurcation. While the various sound waves produced by music can be isolated into individual frequencies, with some being more dominant than others, noise contains jumbled frequencies of sound without a dominant frequency. However, ambiguity lurks beneath this observation. Despite Western music’s self-perception of “noiselessness,” such sounds do exist within the organized matrix of frequencies.

Performers, scholars, and aficionados have long understood Western music (esp. concert music) as purified of noise. This assumption surfaces in descriptions of non-European musics. As Dena J. Epstein chronicles in her article “The Folk Banjo: A Documentary History,” European travelers and missionaries regularly described the timbres of African vocals and instruments as “crude,” “wild,” “peculiar,” strange,” “weird,” or “noise.” Contemporary ethnomusicologists credit “ethnic” musics for retaining noisy elements, and eschewing—or never developing—the Western affinity for “pure” tones. The African mbira, or thumb piano, is a favorite example. Bottle caps and snail shells are attached to the soundboard and resonator, creating a buzz that muddies the otherwise focused timbre of the plucked idiophone. Efforts to reintroduce “noisiness” into Western music, notably with fuzz and overdrive guitar distortion, is sometimes heard as an aspirational return to naturalistic sound, albeit through electronic means.

All of this overlooks the presence of noise in even the most cleaned-up Western musical forms. The scraping of the bow against a violin string; the clacking of the keys on a clarinet; the sliding on the fingerboard of an acoustic guitar. According to filmmaker and composer Michel Chion, author of Sound: An Acoulogical Treatise, the Western listener tends to “scotomize,” or mentally delete, these sounds. Moreover, studio recordings tend to minimize or mute out such idiosyncrasies. “On the other hand,” writes Chion, “recordings of so-called traditional musics are often made by and for people who find something charming about such noises, and such documentations strive to preserve them and even to emphasize them in the recording process.”

Chion’s compositional medium, musique concrète, places all sorts of sounds into a musically organized framework. Compositions consist of multifarious field recordings, which are modified by altering pitch and intensity, extending or cutting off, adding echo effects, playing backwards, and so on. [Listen to Chion’s Requiem]. The finished piece is an artistic unity that challenges standard ideas about music. It can also train us to hear assembled noises as musical, and to listen for noise elements in conventional music.
