A theory layer for your piano tutorial videos
A MIDI file tells you which notes were played. VoicingFlow helps you show the chord, function, scale relationship, tension structure, harmonic motion, and contextual voicing fit behind those notes.
VoicingFlow is not just a falling-notes MIDI renderer. It shows what the notes mean: chord symbols, chord-scales, guide tones, tensions, upper structures, cadence arrows, theory-aware note labels, Voicing Balance, and contextual Voicing Fit analysis.
A MIDI file tells you which notes were played. VoicingFlow helps you show the chord, function, scale relationship, tension structure, harmonic motion, and contextual voicing fit behind those notes.
A voicing is not just a stack of notes. Its meaning changes depending on the harmonic context.
VoicingFlow 1.2 introduces Voicing Fit, a contextual analysis system that evaluates how well the current voicing works over the chord you provide.
Record, author, preview, export, and combine with your teaching footage.
Record your musical examples with a MIDI keyboard while simultaneously recording video of your hands. Because the MIDI and video are captured at the same time, they stay in sync.
Launch VoicingFlow and open the MIDI performance. The app analyzes the file and moves through each musical moment where harmonic context can be added.
At each frame, play the basic harmonic reference chord — always a root-position seventh chord or triad — using MIDI-IN.
VoicingFlow adds chord symbols, chord-scales, guide tones, tensions, note labels, upper structures, and cadence motion.
Save the original performance plus the harmonic information you added, so the file can be reopened later with all theory displays already prepared.
Render the final theory visualization and combine it with your hand-performance footage and teacher explanation in your video editor.
This demo lesson shows how VoicingFlow can turn a jazz piano example into a clear theory-aware tutorial, with chord symbols, chord-scales, guide tones, tensions, harmonic motion, and voicing analysis visible while the music plays.
Instead of only showing falling notes, the video helps students understand what the notes mean harmonically — the chord, the scale relationship, the upper structures, the musical context, and how the voicing behaves inside that context.
Watch on YouTubeVoicingFlow turns your harmonic analysis into a visual teaching layer.
A MIDI file only knows which notes were played. It does not always know what those notes mean.
The same voicing can function as a stable chord-tone structure, a colorful upper structure, a suspended dominant sound, an altered dominant color, or a risky avoid-tone sonority depending on the harmonic context.
VoicingFlow lets you add the intended analysis by playing simple reference chords. Then the app can show not only the chord symbol and chord-scale, but also how the current voicing fits that context.

Voicing Fit analyzes how well the current voicing works over the harmonic context you provide. It looks at chord tones, guide tones, tensions, avoid tones, register behavior, acoustic density, and overall harmonic usefulness, then gives the voicing a rating such as Risky, Usable, Strong, or Excellent.
No. Voicing Balance describes intrinsic properties of the voicing itself, such as spacing, range, density, and note distribution. Voicing Fit is context-dependent: the same voicing can be Excellent over one chord, Strong over another, and Risky over a different harmonic context.
No. Voicing Fit depends on the harmonic context you provide. You play a simple root-position triad or seventh chord as the reference, and VoicingFlow analyzes the current voicing against that context. This keeps the result musically intentional instead of relying on generic chord guessing.
