Explore the hidden geometry of chromatic harmony through Neo-Riemannian Theory — an elegant mathematical framework for understanding how major and minor chords connect through smooth voice leading. TAP ANY CHORD Touch any of the 24 major and minor triads arranged in the Cube Dance. Watch the chord light up and hear it ring out as a sustained pad. APPLY TRANSFORMATIONS Six Neo-Riemannian operations (L, P, R, N, H, S) connect chords by moving one or two voices by a semitone. Each button shows you the target chord before you tap it. CONTINUOUS VOICE LEADING The audio engine keeps common tones sustained and moves only the voices that change. Choose from five sound presets: Rhodes, Strings, Choir, Organ, or Synth Pad. THEORY REFERENCE The built-in Theory tab explains every operation with voice-movement diagrams, hexatonic cycles, Weitzmann regions, and academic references from Riemann (1893) to Douthett & Steinbach (1998). Perfect for music theory students, composers, and anyone fascinated by the mathematics of harmony.

About

MindAttune

Features
Read full description

MindAttune is a generative artwork for iPhone and iPad — a field of soft, luminous voices that drift endlessly in and out of alignment and never play the same moment twice. Nine sustained tones, each tuned to a calming frequency and given its own slow loop of a slightly different length, are set running together. Because no two loops share a common cycle, the voices slide forever against one another — gathering into chords that bloom, dissolve, and never quite recur. Always different, always the same. Watch bands of warm-to-cool light swell and fade. Turn on the sound and the same system becomes audible: an ever-shifting ambient drone you can sink into. Then simply leave it running — as a focus aid, a calm corner of your day, or something to drift off to. Every frame is generated live on your device. Nothing is pre-recorded and nothing loops; what you see and hear right now has never existed before and won't return. Features A living generative field — never the same twice Ambient sound tuned to nine calming (Solfeggio) frequencies, driven by the same drifting clock as the visuals Hands-on controls: voices, drift rate, sound-to-silence balance, incommensurability, bloom, sway, and a custom color palette Seeded compositions — find a configuration you love and return to any time Immersive full-screen mode Plays through the speaker, earphones, or external speakers Runs entirely offline Plant a few seeds, set the conditions, and watch what grows.

Verdict

The call

The clearest difference is price: MindAttune at $1.99 against Neo's $2.99. MindAttune also leads on iOS requirement (16.0 vs 18.0). On ads, in-app purchases and device support there is nothing between them.
