Having dedicated almost forty years of scholarship to exploring the rich and varied music of Sumatran provinces, Margaret Kartomi provides a fascinating ethnographic record of vanishing musical genres, traditions, and practices that have become deeply compromised by the pressures of urbanization, rural poverty, and government policy. This deeply informed collection showcases the complex diversity of Indonesian music and includes field observations from six different provinces: Aceh, North Sumatra, Riau, West Sumatra, South Sumatra, and Bangka-Belitung. Featuring photographs and original drawings from Kartomi's field observations of instruments and performances, Musical Journeys in Sumatra provides a comprehensive musical introduction to this neglected, very large island, with its hundreds of ethno-linguistic-musical groups.
