This paper draws on the African–American composer Olly Wilson’s notion of a ‘‘heterogeneous sound ideal’’ in which the author discusses the common preference for certain sound combinations and timbres in African and African–American musical traditions. The purpose of this presentation is to demonstrate, in detail, specific aspects of this concept by drawing on a variety of instrumental and ensemble traditions from sub-Saharan Africa with focus on the manipulation and intentional modulation of timbres that characterize much of the musical traditions of sub-Saharan Africa and which are often overlooked by analysts. The paper argues that this common emphasis on ‘‘unusual’’ timbres constitutes one of the major parameters distinguishing sub-Saharan African musical traditions from those of European art music traditions. A ‘‘heterogeneous sound ideal’’ suggests new approaches to the identification, measurement, evaluation, and appreciation of acoustic phenomena in the contexts of sub-Saharan African musical traditions. Additional demonstrations involving spectral–timbral projections of individual and ensemble instruments will be presented.
