Abstract: This method and system is primarily implemented for multiple computers-guided performance by an ensemble of musicians utilizing the Internet/Intranet network. Different parts (“sheet music”), accompanying sounds, instructions, etc., of a larger, multi-layer composition are individually controlled and automatically displayed at appropriate times onto the respective monitors of multiple computers. These multiple parts are loaded without user input, individually timed and retrieved for each computer. Different elements of the composition are separately displayed for each of the performers, in such a way that when executed together they create a unified totality of the composition/presentation. This system has a number of possible configurations, such as controlling contemporaneous, multicontent classroom instructions and/or artistic presentations.
