GEMINA 3D Visualizer
Web app
Interactive 3D views of the double hexagon lattice — move through pitch space, highlight sets and hear harmonic relationships.
Geometric Musical Interface Analyzer
GEMINA
Geometric Musical Interface Analyzer
A visual music system for exploring harmony, symmetry and pitch space.
What is GEMINA?
GEMINA maps the 12-tone chromatic universe into an interactive geometric space built from two interlaced whole-tone hexagons. Chords, scales, modes and interval relationships become visible structures you can rotate, reflect and hear against each other.
It grew out of the same musical imagination that spends nights on Hammond drawbars and trio interplay — a way to think about pitch-class sets, voice-leading and symmetry with the hands and ears, not only on paper.
Below you will find prototypes and research tools; further down, the language becomes more technical for readers who want the structural detail.
GEMINA is not a band or a conventional release project; it is the research and application line where keyboard culture meets mathematics, code and new interfaces.
Apps & prototypes
GEMINA Analyzer
In development
Analysis views for chords and scales as geometric objects — interval vectors, symmetries and common transformations.
GEMINA Sketch
Prototype
Lightweight sketching surface for trying ideas quickly — sequences, transpositions and modal paths in the lattice.
GEMINA XR experiments
Experimental
Early spatial and XR prototypes — walking around harmonic structures instead of only looking at a flat screen.
Core concepts
- Two interlaced whole-tone hexagons as a 12-point chromatic scaffold
- Structural axes and reference directions inside the lattice
- D6 symmetry operations acting on the chromatic aggregate
- Rotations and reflections as musical transformations
- Chords, scales and modes represented as geometric objects
- Interactive listening and simple sequencing tied to the geometry
- Roadmap toward XR and spatial music interfaces
Demos
Video walkthroughs, screen recordings and embeddable demos will appear here as they are published.
No public demo reel yet — follow the journal for the first drops.
Development journal
Build notes, theory sketches and interface experiments — tagged around GEMINA, visual music, music theory, app development and XR.
Research & technical notes
Repositories and longer write-ups for collaborators and curious musicians with a technical side.
Future direction
Education
Workshops and side programmes where students meet harmony through geometry — connecting organ trio vocabulary to the same structures GEMINA visualises.
Composition
New pieces and improvisations that treat the lattice as a score — feeding concert programmes and recordings back into the software.
Immersive interfaces
Spatial audio and XR experiments that let ensembles and audiences inhabit the same geometric space during performance.
