The tacit knowledge of the actor / singing actor / actor musician comprises complex phenomena. Any attempt to pass these skills on to a student actor requires participation in embodied experiences. Immersive training facilitates the development of technical and expressive skill; physical, intellectual, emotional, and social sensitivity; and the ‘muscle’ required to maintain performance stamina. Dalcroze is a body-based approach to training and pedagogy developed by Emile Jaques-Dalcroze in the early-twentieth century. Originally intended for musicians, its influence on theatre and movement began with Laban and Stanislavsky, and continued through generations of practitioners since. It now has a wide range of applications in the Arts and Education. The core of Dalcroze focuses on experiencing, expressing and understanding music in and through movement; ear training focuses on pitch and pitch relationships, including harmony; improvisation with instruments, voice and movement develops creativity and an ability to match sound and movement. This paper outlines the history of Dalcroze and charts its lineage and influence on actor training.
