Abstract
This paper explores parallels between esotericism and experimentalism in 20th century music. Following an outline of and argument for the human impulse for esotericism, it offers a broad definition of experimentalism in musical practice. Theosophy is contextualised in relation to the Traditionalist School and the increased flow of eastern teachers, philosophies and practices being introduced to the West during the 20th century. Influences from these three intertwined sources are then traced in relation to a number of artists including Henry Cowell, John Cage, and Stockhausen. Areas of commonality across these spiritual and esoteric traditions are then identified on the basis of motivation, practices and methodologies, principles and perceived goals. Finally, parallels are made with characteristics of certain experimental musical practices to suggest and explore the possibility of links between these artists and their work with spiritually informed thought and practice.
