## Description

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.
