Product information
Overview
Music Mouse is an algorithmic composition tool that helps users create music through interactive performance rather than traditional note-by-note editing. Originally created by composer Laurie Spiegel, it generates harmonically coherent musical ideas based on simple mouse movements and keyboard input. The browser-based version brings this classic concept to modern platforms, making it easy to explore generative music without installing dedicated software.
Algorithmic Composition
Instead of composing every note manually, Music Mouse continuously generates melodies and harmonic progressions that follow the selected musical scale and tonal rules. Users influence the performance in real time, allowing ideas to evolve naturally while maintaining musical consistency. This interactive approach makes Music Mouse an accessible introduction to algorithmic composition and a creative tool for musicians, educators and anyone interested in exploring generative music techniques.
