Maryanne Amacher (1938 – 2009) was a composer of large-scale fixed-duration sound installations and a highly original thinker in the areas of perception, sound spatialization, creative intelligence, and aural architecture. She is frequently cited as a pioneer of what has come to be called “sound art,” although her thought and creative practice consistently challenge key assumptions about the capacities and limitations of this nascent genre.  Often considered to be a part of a post-Cagean lineage, her work anticipates some of the most important developments in network culture, media arts, acoustic ecology, and sound studies.

Amacher was born in 1938 in Kane, Pennsylvania, a small town in the northwestern part of the state, just south of Erie. Her formative years were spent in Philadelphia, where she enrolled in the University of Pennsylvania in 1955. As a music major, she studied with composer and theorist Constant Vauclain, George Rochberg, and the prominent German avant-garde composer Karlheinz Stockhausen during his tenure in Philadelphia in 1964 and 1965.

After her work at University of Pennsylvania, Amacher went on to hold a series of fellowships at the University of Illinois’ Studio for Experimental Music, MIT’s Center for Advanced Visual Studies, SUNY Buffalo, Capp Street Gallery in San Francisco, and many others, also internationally. In the late 1960s, while at SUNY-Buffalo, Amacher pioneered what she called “long distance music,” or telematic, site-related works that would later crystallize into her renowned City Links series. During her time as a fellow at MIT’s Center for Advanced Visual Studies (1972-1976) she began developing her “ear tone” music with the help of Marvin Minsky’s Triadex Muse, a synthesizer and compositional tool utilizing principles of artificial intelligence. Amacher’s “ear tone” music emerged from creative use of combination and difference tones, along with otoacoustic emissions, or sounds produced spontaneously within the cochlea. She followed developments and debates in otological research on OAEs and other psychoacoustic phenomena closely. Such independent scholarship was an important stimulus to Amacher’s career-long research into “ways of hearing” and the creative potentialities of how the ear itself processes sounds both of itself and in situ.

By her own account, Amacher’s work is best represented by three multimedia installation series produced in the United States, Europe, and Japan between the late 1960s and her death in 2009.  In these major works, City Links (1967-1980), Music for Sound Joined Rooms, and the Mini Sound Series, Amacher refashioned composition as a dramatically staged creative undertaking in experimental acoustics. She was fascinated with the physicality of sound, the way it propagated in space, and the unexpected ways that it provoked images and sensations in the “mind’s ear.” Her approach was slow, deliberate, and empirical. She would spend hours listening to seemingly unchanging tones or making minute adjustments to loudspeaker placement. For Amacher, these things were not details or minutiae: they were the very heart of her work, the equivalent to the painstaking working out of themes or harmonic progressions in traditional music.

In City Links, Amacher transmitted live sonic feeds from multiple cities (or multiple sites in the same city) via high-quality telephone lines and mixed these sources live during exhibitions, concert presentations, or radio broadcasts. In City (1967), a 28 hour live mix, connected eight locations around Buffalo via phone lines to WBFO. The program was recognized by the Institute for Education by Radio and Television for its innovative, experimental approach to radio’s role in fostering social community. In City Links, Amacher reflected upon the changing sense of place created by the general public’s access to air travel and telecommunications. Work titles often reflected these themes (e.g. No More Miles and Tone of Place). It was a prescient tremor of the “network culture” thematics to come in recent media art. Through 1979, she realized 21 iterations of her City Links series, many of which were collaborations with visual artists and/or architects. They took the form of installations, performances, and combinations of both.

The second work group is a site-specific series called Music for Sound Joined Rooms.  In these works, Amacher used idiosyncratic speaker placements (facing walls or the floor of her installation space) to send sound through the solid medium of built space before allowing it to circulate in air, creating multiple, overlapping acoustics. Opposed to the usual air-borne transmission of sound waves (the single carrier medium for all traditional Western music), she referred to this practice in her writing as structure-borne transmission. In such works, the architectural site of the installation itself became the physical medium of the work, shaping and coloring the sounds as they propagate through it. The first piece in this series was Living Sound: Patent Pending (1980), presented as part of the Walker Art Center’s New Music America programming. Amacher described it as follows:

The house, on a hill in St. Paul with its panoramic view of Minneapolis, was lit by tall quartz spots, as if a movie set. The time: midnight. [In the] music room, where two grand pianos had been, was now an “emergent music laboratory,” there were 21 petri dishes with something growing in them — the musicians and instruments of the future. DNA photos and biochemical diagrams were placed on music stands. Meanwhile, the entire house was full of a spectacular sound — incredibly loud and unbelievably dense — sound, circulating throughout the rooms, out the doors and windows, down the hill, past sedate Victorian mansions. It seemed to contain the energy of all frequency ranges at once, yet never approached white noise. [Listeners] felt themselves pushed, as if by acoustic pressure, out into the garden, where the entire house was heard, sounding, as a gigantic instrument. 

Finally, Amacher’s Mini Sound Series is comprised of a group of multimedia installations based on the television miniseries format. In the Mini Sound Series, an ensemble of “sound characters” distinguished by unique timbral, gestural, and contour profiles interact and develop in relation to each other over several days or weeks, following dramatic narrative techniques drawn from television and other popular forms in a serial format. Mini Sound Series was an important departure from the conventions of endless-duration sound installation practices, which Amacher found to be asking overly diffuse attention of the listener, as well as from the conventions of fixed-seating concert listening, which she found aggressively disciplinary. Instead, Amacher explains, the Mini Sound Series allows, “people to return and identify certain characters, having gotten to known them in [previous] features.” Uniting all of these works is a holistic concern with the entire network of processes that comprise the ex

perience of music—in her own words, such a set of processes emphasizes that, “how certain sounds are to be perceived in a sonic world becomes as important as the sounds themselves.”

As the spatial “staging” in both Music for Sound Joined Rooms and Mini Sound Series became increasingly critical to the work series’ articulation, Amacher began developing visual components that functioned to both heighten the overall aesthetic experience of a visitor and to also guide visitors through the series of rooms that would frame a given work. These visual components were comprised largely of original videos and slide projections, but also included scrolls, 3D-images, objects, and texts.
