Most scholars writing on the use of samplers express anxiety over the dissolution of boundaries between human-generated and automated musical expression, and focus on the copyright infringement issues surrounding sampling practices without adequately exploring samplists' musical and political goals. Drawing on musical examples from various underground electronic music genres and on interviews with electronic musicians, this essay addresses such questions as: What is a sampler, and how does the sampling process resonate with or diverge from other traditions of instrument-playing? How do electronic musicians use the ‘automated’ mechanisms of digital instruments to achieve nuanced musical expression and cultural commentary? What are some political implications of presenting sampled and processed sounds in a reconfigured compositional environment? By exploring these issues, I hope to counter the over-simplified, uninformed critical claims that sampling is a process of ‘theft’ and ‘automation’, and instead offer insight into the myriad and complex musical and political dimensions of sampling in electronic music production.
