Gammalan is an interactive musical experience that uses music information retrieval techniques in conjunction with game design principles to engage audiences in creative behavior that combines the power of familiar songs with neural entrainment on multiple temporal scales.
A preliminary system analyzes and processes existing recordings, manipulating properties such as rhythm and harmony, while introducing synthesized frequencies in a musically informed manner. The recordings are then presented in an exploratory 3D game-like environment that encourages active and playful engagement with the recorded music.
