This chapter focuses on systems and interfaces for multimodal analysis of expressive gesture as a key element of music performance. Research on expressive gesture became particularly relevant in recent years. Psychological studies have been a fundamental source for automatic analysis of expressive gesture since their contribution in identifying the most significant features to be analysed. A further relevant source has been research in the humanistic tradition, in particular choreography. As a major example, in his Theory of Effort, choreographer Rudolf Laban describes the most significant qualities of movement. Starting from these sources, several models, systems, and techniques for analysis of expressive gesture were developed. This chapter presents an overview of methods for the analysis, modelling, and understanding of expressive gesture in musical performance. It introduces techniques resulted from the research developed over the years by the authors: from early experiments of human-robot interaction in the context of music performance up to recent set-ups of innovative interfaces and systems for active experience of sound and music content. The chapter ends with an overview of possible future research challenges.
