We invite submission of proposals that showcase new interfaces for musical expression in composition and performance. We encourage submissions that expand, reform, and refine our understanding of NIME in the performance, conceptualization, and reception of music. We look forward to receiving submissions that respond to the conference theme of “Mirrored Resonances” in any of the many ways it might be interpreted. For example, one of the topics, “off-the-shelf NIME”, encourages exploration of the presence and use of inexpensive, commercially available NIME as a kind of mirrored resonance of the non-commercial, academic research that often enabled them. Many of the conference thematic areas similarly afford connections with the larger conference theme, and we encourage submissions exploring these implications.
