I had one of my guide improvisation compositions performed by the SFCCO. Open Ended is a very versatile work that is composed before your eyes. This work has no set instrumentation and can be played by any number of performers. It also has no set length; the piece could last 5 minutes or 24 hours. Based on Rova‘s Radar techniques, Open Ended is less of a composition and more of a color or tool palette. It is an ever-growing collection of rules and games for the performers that are triggered by hand signals by the conductor/composer. The conductor/composer then composes the piece live using these hand signals to guide the performers. Open Ended has been performed several times but every time it is a world première and unique performance that can never be repeated.
