The Bucket System is a new system for computer-mediated ensemble improvisation, designed by improvisers for improvisers. Coming from a tradition of structured free ensemble improvisation practices (comprovisation), influenced by post-WW2 experimental music practices, it is a signaling system implemented with a set of McMillen QuNeo controllers as input and output interfaces, powered by custom s...

This paper presents a novel computational model of jazz improvisation based on n-gram language models. Recent functional neuroimaging studies suggest that the brain processes structural elements of improvised music and conversational language in a similar manner. We hypothesized that if musical improvisation and language share a common cognitive and neurological foundation, then statistical tec...

This paper describes a reactive architecture handling the hybrid temporality of guided human-computer music improvisation. It aims at combining reactivity and anticipation in the music generation processes steered by a “scenario”. The machine improvisation takes advantage of the temporal structure of this scenario to generate short-term anticipations ahead of the performance time, and reacts to...

Improvisation is an articulated multidimensional activity based on an extemporaneous creative performance. Practicing improvisation, participants expand sophisticated skills such as sensory and perceptual encoding, memory storage and recall, motor control, and performance monitoring. Improvisation abilities have been developed following several methodologies mainly with a product-oriented persp...

How do music therapists experience themselves in clinical improvisation in music therapy? The aim of this inter-disciplinary study is to show how music therapists describe and experience the life-world of the self in clinical improvisation through phenomenological investigation. Informed by sociological social psychological theory proposing that the self develops in social discourses, this stud...

This paper describes an experiment of using a variant of the TSP (Traveling Salesman Problem) of ACO (Ant Colony Optimization) and automatic fitness in the evolutionary algorithm to create jazz improvisation solos. It is a subproject of our overall EJI (Evolutionary Jazz Improvisation) project, where we try to explore the inner nature of jazz music and model jazz improvisation solos and jazz ha...

This thesis investigates the cognitive foundations of collaborative musical free improvisation. To explore the cognitive underpinnings of the collaborative process, a series of experimental case studies was undertaken in which expert improvisors performed with an artificial agent. The research connects ecological musicology and subsumption robotics, and builds upon insights from empirical psych...

Improvisation is rapidly becoming an important issue for both scholars and practitioners. Organizations that operate in turbulent environments must learn to swiftly adapt and respond to such instability, especially in areas as innovation and new product development. In such contexts, traditional top-down, carefully-planned approaches to innovative projects may represent an obstacle to effective...

Software development teams are increasingly faced with unanticipated obstacles to effectiveness that require extemporaneous actions. Team improvisation has been identified as an important team situated response to emergent challenges to team effectiveness. However, the efficacy of team improvisation is not well understood in the context of software development teams—which perform complex, knowl...
