A lot happens when we press play. To prepare, we select a particular format of sound storage—maybe vinyl, magnetic tape, polyethylene, or an mp3—for the parsing, processing, and amplification of that format's content. Once things start moving, we inaugurate a listening experience that may seem effortless, but which has undergone meticulous social conditioning, and which is informed by our own deep histories of listening, aurality, and attention. In the long term, this process is not as rigid as it sounds: listening has always been flexible, and historians of the concert hall have told us a twisting and turning story about audiences who did not always think it was proper to stay silent, and who did not always feel the need to pay much attention to what took place in front of them. But today, anyone who chooses to play a spoken word compilation instead of a jazz LP (long-playing record) at a cocktail party might not find such a receptive crowd. Facilitated by internet streaming and downloading, this relatively new ability to amass intensely personal sonic archives often clashes with the contextual demands of where, when, and how certain forms of listening are meant to be enacted: the cocktail party often dictates a particular aural accompaniment, one more amenable to music than an audiobook. For such a widely practiced activity, why do the modern activities of storing, distributing, and amplifying sound, which have grown kaleidoscopically complex in the twentieth and twenty-first centuries, remain undertheorized in Slavic studies? What would it mean to think about these questions and their repercussions in east European modernity? And what might listening to east European history and culture tell us that our other senses cannot?
