1904 w/ Otto Abraham in Zeitschrift fur Ethnologie  "On the significance of the phonograph for comparative musicology," "Turkish melodies recorded on the phonograph," "Indian melodies recorded on the phonograph."
review of Lach "On an interesting special case of 'color audition.'" 1906 /w Abraham "Indian melodies from British Columbia recorded on the phonograph," "Tunesian melodies recorded on the phonograph."

p. 78 "The cultural data of phonograph records was importantly a matter of representation....In many respects it was their physical quality as standardized, mass-produced goods taht helped to enforce their quality as specific cultural data, even as the culture they representd proved variable and unspecific in the extreme....What I am suggesting is that phonograph records frequently proved transgressive of the very cultural categories that they helped to represent as distinct or specific."

Must see "Local Meetings and Other Notices" for discussion of phonograph.

This was the most popular journal for professional ethnographers publishing text-based research in early 20th c. Between 1890-1935 (yrs of phonograph's most extensive use), 384/485 instances in which full texts are presented as complete, verbatim transcriptions of material collected in the field make no mention of circumstances under which texts taken down. Only 12 articles mention phonograph at all, usually concerned specifically with method and procedure.

By 1908 "Boasians" took over for 30 yrs.  Used phonograph to fulfill Boas's mandate to pursue the "people['s] records of themselves in their own words."
