This book constitutes the thoroughly refereed post-proceedings of the Third International Computer Music Modeling and Retrieval Symposium, CMMR 2005, held in Pisa, Italy, in September 2005.

The 24 revised full papers presented were carefully selected during two rounds of reviewing and improvement. Due to the interdisciplinary nature of the area, the papers address a broad variety of topics. The papers are organized in topical sections on sound synthesis; music perception and cognition; interactive music: interface, interaction, gestures and sensors, music composition; music retrieval: music performance, music analysis, music representation; as well as interdisciplinarity and computer music.
