The FretMotion Engine
Music Intelligence.
FretMotion is powered by a music theory engine built entirely from first principles.
What It Understands
The engine encodes deep knowledge across multiple musical domains, all woven into a single coherent model.
Harmony
How chords relate to keys. What substitutions work and why. How to reharmonize a progression without breaking it. The engine understands harmonic function the way a conservatory-trained musician would.
The Fretboard
Not just note positions, but what's actually playable. Finger reach, string transitions, barre chord shapes, open strings, capo chart optimization, alternate tunings. The full physical map.
Voice Leading
The art of moving between chords with minimal effort and maximum musicality. The engine finds the smoothest path through any chord progression, automatically.
Theory at Scale
Hundreds of chord types, dozens of scales and modes, multiple tuning systems, all interconnected. A guitar chord dictionary and scale reference, computed on the fly.
What It Does
Behind FretMotion tool, the engine is doing the hard work.
- Identifies any chord from fret positions
- Finds the easiest way to play a complex chord
- Optimizes an entire progression for smooth transitions
- Detects which key your song is in
- Transposes to any key and finds the perfect capo position
- Suggests harmonic substitutions
- Converts your progression into different musical styles
- Builds targeted practice routines from your hardest transitions
