We investigate the use of interactive sound feedback for dance pedagogy based on the practice of vocalizing while moving. Our goal is to allow dancers to access a greater range of expressive movement qualities through vocalization. We propose a methodology for the sonification of Effort Factors, as defined in Laban Movement Analysis, based on vocalizations performed by movement experts. Based on the experiential outcomes of an exploratory workshop, we propose a set of design guidelines that can be applied to interactive sonification systems for learning to perform Laban Effort Factors in a dance pedagogy context.
