CHRISTOPHER J. TUCKER, while a student at University of Michigan, Ann Arbor, Michigan, received funding in June 2002 to aid research on ''Sowing Ayacucho' on Disc: Music, Media and the Ayacuchano Imaginary,' supervised by Dr. Judith O. Becker. The grantee conducted his dissertation fieldwork on music and media in the Andean city of Ayacucho, Peru, as well as among migrants in Lima. He primarily focused upon the ways in which recorded Ayacuchano music is used by performers, mediators, and listeners in the process of redefining a sense of regional community for both migrants and those in the highlands. During the period of research funded by Wenner-Gren, he interviewed dozens of key composers, performing artists, producers, radio personalities, local intellectuals, and fans whose mediated interactions determine the ways in which the music is formatted and marketed to a group constituted as the 'Ayacuchano community .' These activities were augmented by focused observation at their workplaces and other relevant areas, aimed at elucidating the significance of the interactions that occur at such strategic points as the recording studio, broadcast booth, and sites of reception. He also conducted archival research, examining older newspapers and magazines to determine how such processes have unfolded in the past. By following the music through the media circuit that links the highland area to the capital, broadcast booth, and sites of reception, he determined how musical discourse is helping to reposition ideas about what it means to be Ayacuchano, migrant, indigenous, and mestizo in the changing social context of contemporary Peru. He also explored how this musical style has expanded from its original regional base, to serve as a vehicle for an emerging Andean migrant middle class in the nation's capital.
