Reflex Invisible Score

An original and innovative notation technique used to create Reflexive Music. The Reflex Invisible Score, developed by composer, interdisciplinary artist and performer Keren Rosenbaum since 1992. The original arranging and scoring of events creates a surprising  integration of sound, visual play and physicality. The method also incorporates lighting, video, and interactive mediums in new technology.  The unfolding of the score allows for a simultaneity in multiple events that becomes a completely unique experience and opens up the boundaries of musical expression.

Using outside triggers such as earphone triggers visual triggers, movement triggers and others. The invisible score notation requires from performers an improvisatory freedom in a very strict structural environment.  The performers follow internal inspirations to respond and engage in conversations and at the same time are interrupted by earphone triggers that force them into an invisible structure.


The triggered events are notated and allows a much advance manipulation of the composition and at the same time affects and influences the improvised outcome. This ongoing project has been successfully performed and practiced by Reflex Ensemble members as well as many performers and students around the world.  As a practice, it fascinates with its complexity and immediacy, and as a performance it is constantly surprising as it reveals the human-ness within structure.


The Reflex Invisible Score methodology was published in the book Notations 21 book by Theresa Sauer in 2009. The original notation and music scores became the foundation ALP Approach and the ALP Tools are all based on Reflexive Music Scores originally performed by the Reflex Ensemble. ALP (Active Listening Playground) Approach can be learned and practiced in the Reflexive Music Academy founded under Composing Community Global Organization.
