Riemann is an advanced harmonic composition and analysis software designed for composers, arrangers, and musicians interested in applying Riemannian theory in a creative and practical way.

Starting from a root chord, Riemann allows users to apply various Riemannian transformations to automatically generate chord progressions, which can be both visualized and exported directly as MIDI files, ready for use in DAWs and music production environments.

The software also enables users to write and develop coherent melodic lines over Riemannian chord progressions, facilitating the integration of harmony and melody in a structured and musical way.

Thanks to a system based on harmonic polygons, users can explore and generate multiple transformations from a single structure, expanding compositional and experimental possibilities. By inputting a chord progression, Riemann can also perform a detailed harmonic analysis, identifying the specific Riemannian operations applied at each step.

Riemann combines theoretical rigor with creative workflow, transforming complex harmonic concepts into an intuitive, powerful, and immediately usable tool for contemporary composition and film scoring.
