MindAttune vs SetClass

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.

SetClass is an interactive tool for exploring Pitch Class Set Theory — the analytical framework behind atonal and post-tonal music, from Schoenberg and Webern to contemporary composers. BUILD & HEAR Tap notes on the chromatic wheel to construct any chord, scale, or pitch collection. Hear it instantly with a jazz piano soundfont or built-in synthesizer. EXPLORE THE THEORY • Normal form, prime form, and Forte number for every set • Interval vector analysis • Transpositional and inversional symmetry • Z-relation detection TRANSFORM Apply serial operations: transposition (T0–T11), inversion, retrograde, retrograde inversion, and multiplication (M5, M7, M11). Watch the geometry change in real time. COMPOSE & SEQUENCE • Sequencer: build rhythmic patterns with serial transformations, arpeggios, swing, gate, and glide • Melody Generator: create melodic lines with contour control (free, rising, falling, arch) • Morph: blend smoothly between two sets with optional portamento • Export to MIDI or MusicXML FIND & GENERATE • Set Finder: enter any melody or chord and identify the pitch class set inside • Generator: produce sets by cardinality, symmetry (mirror, symmetric), and density LEARN Built-in theory reference covering pitch classes, normal form, prime form, interval vectors, Forte numbers, transposition, inversion, retrograde, symmetry, Z-relation, set class, morphing, and serial technique — with musical examples from Debussy, Schoenberg, Bartók, Webern, Berg, Stravinsky, and Messiaen. Available in English, Spanish, French, Italian, German, and Chinese.
