SetClass vs WEAR Texture Processor

Explore the building blocks of modern harmony. This app lets you see, hear and manipulate pitch class sets, the foundation of post-tonal and atonal music theory. EXPLORE • Tap notes on the pitch wheel to build any chord or scale. • See the Forte number, prime form, normal form and interval vector. • Check transpositional and inversional symmetry. • Open the K/Kh complex of any set to see which set classes include it or its complement. FIND • Tap notes on a keyboard, or type a Forte number (3-11, 6-Z44) or pitch-class numbers (0 4 7). • Browse all 224 Forte set classes, with Z-relations, filtered by size. TRANSFORM • Transpose, invert and multiply (M5, M7) any set. • Morph smoothly from one set to another. CREATE • Generate sets by cardinality, symmetry and density. • Arrange sets into rhythmic sequences using P, T, I, R and RI operations, with every inversion level. • Build a serial matrix from rows of 2 to 12 notes. • See each set as geometry in tonal space, with symmetry axes. • Export to MIDI and MusicXML. LEARN • A built-in theory guide. • Analysis examples from Debussy, Schoenberg, Stravinsky, Berg, Messiaen and more, with links to scores. Built for students, composers and theorists, from first-time learners to advanced analysis.

WEAR is an AUv3 texture processor designed for making audio feel uncertain. WEAR makes no sound on its own—it is an audio effect designed to be loaded inside a compatible AUv3 host. Place it after pianos, guitars, vocals, drums, synthesizers, field recordings, or other audio sources to introduce filtered, warbled movement and texture. Built around instability, movement, and degradation, WEAR reshapes incoming audio through a collection of processes designed to add character. RATE and DEPTH introduce pitch modulation. GATE responds dynamically to the incoming signal, allowing quieter material to become increasingly unstable while louder sounds push through. FILTER reshapes the frequency range, while GRIME, WASH, and ROOM introduce different forms of texture, space, and degradation. The result can range from subtle movement to extreme transformation depending on what you dial in. WEAR intentionally includes no presets. Its behavior depends heavily on the material being passed through it, so it is designed to be adjusted by ear for each sound rather than treated as a collection of fixed effects. Exploration is encouraged.
