This article presents a history of mediated pedagogy in the Suzuki Method, the first widespread approach to learning an instrument in which sound recordings were central. Media are conceptualized as socially constituted: philosophical ideas, pedagogic practices, and cultural values that together form a contingent and changing technological network. Suzuki's early experiments in the 1930s and 1940s established central ideas: the importance of repetition in learning, the recording as teacher, a place for mothers in assisting learning, and the teachability of talent. Suzuki also refined approaches to learning through specialized modes of listening as he examined tens of thousands of student graduation tapes. During the 1960s, Kendall published the first translation of the method in the United States, and his correspondence with Suzuki along with writings for teachers provide a window into evolving pedagogic practices. The method's mediated pedagogy changed radically in the 1970s as cassette tapes allowed students to be easily recorded for the first time. The article also considers cultural values the contingency of media through the vastly different acceptance of recordings in the Japanese and US contexts, including efforts by Kendall during the 1980s to eliminate Suzuki's controversial practice of advanced recitals played to recorded accompaniment.
