This project seeks to explore and further develop the concept of "Symbiotic Virtuosity," where artificial intelligence (AI) and human musicians collaborate in real-time as an augmented creative process. In collaboration with GRAMMY-winning keyboardist and technologist Jordan Rudess, we are developing a novel AI-augmented musical instrument that can enhance live performances. By developing personalized generative AI models to reflect the artist's unique style and enabling responsive, real-time musical interaction, we aim to redefine the boundaries of human creativity and live performance. This project addresses a critical gap in the current state-of-the-art by focusing on controllable AI systems that artists can dynamically interact with during live performances and how these augmented musicians are presented to audiences onstage.
