Touch Tonnetz visualizes Neo-Riemannian music theory through the Tonnetz (tonal network) lattice. Tap any chord or note to hear it, see its Neo-Riemannian transformations, and explore harmonic relationships that go beyond traditional tonal progressions. Key Features: Interactive Tonnetz Visualization — Tap any chord or note to hear it and see its Neo-Riemannian transformations highlighted on the lattice Harmonic Analysis — Roman numeral overlays for any tonic, updated in real time Progression Builder — Create, save, and play back melodic progressions Custom Chords — Build and save your own chords for experimentation Three Instrument Sets — Piano, Brass, and Woodwinds, all high-quality samples Six Color Schemes — Three dark, three light Pinch to Zoom — Explore the lattice in detail at up to 4× magnification 7-Day Free Trial — Full access, no restrictions, no nags Perfect For: Composers looking for harmonic paths outside conventional progressions Music theorists studying Neo-Riemannian transformations Musicians experimenting with chord voice-leading Students exploring music theory hands-on What is Neo-Riemannian Theory? Neo-Riemannian theory is a branch of music theory that studies relationships between major and minor triads using transformational geometry. Rather than treating chords as functions within a key (tonic, dominant, etc.), it focuses on the small voice-leading moves — Parallel, Leading-tone exchange, and Relative — that connect one triad to the next. The result is a rich map of chromatic harmony that complements traditional tonal analysis. Why Touch Tonnetz? The Tonnetz lattice makes these relationships spatial: related chords are neighbors, and transformations are visible paths. Touch Tonnetz lets you see the lattice, hear it, and build with it — turning an abstract theoretical framework into something you can explore by ear and by hand.
