What is Harmony MIDI Visualizer?
Harmony MIDI Visualizer is a MIDI harmony visualizer for creating theory-aware piano tutorial videos.
Open a MIDI file and turn it into a clear visual presentation with piano keyboard animation, chord symbols, chord-scales, voicing labels, guide tones, tensions, upper structures, and harmonic context.
Who is Harmony MIDI Visualizer for?
Harmony MIDI Visualizer is for piano teachers, jazz educators, YouTube creators, online course creators, and musicians who make educational content from MIDI performances.
It is especially useful if you teach harmony, voicings, chord-scales, upper structures, reharmonization, jazz standards, improvisation, or modern piano theory.
Does Harmony MIDI Visualizer automatically know the chords from my MIDI file?
Harmony MIDI Visualizer analyzes the notes in the MIDI performance, but you provide the harmonic context.
When the app reaches a new harmonic moment, you play the basic root-position chord that represents the harmony you want the student to understand. Harmony MIDI Visualizer then analyzes the original MIDI performance against that context.
This is intentional. In teaching, the same notes can often be explained in more than one way, so Harmony MIDI Visualizer lets the educator define the musical meaning.
Do I need to play the full voicing into Harmony MIDI Visualizer?
No. You never need to play the full voicing.
To give Harmony MIDI Visualizer the harmonic context, you always play either a seventh chord or a triad in root position, anywhere on the keyboard.
For example, if the MIDI performance contains a complex C-7b5 voicing with tensions, passing notes, or an upper structure, you simply play C-7b5 in root position. Harmony MIDI Visualizer then analyzes the notes from the original MIDI performance against that harmonic context.
What does Harmony MIDI Visualizer show in the video?
Harmony MIDI Visualizer can display animated piano keyboard visualization, chord symbols, chord-scales, guide tones, tensions, upper structures, Roman numeral upper-structure labels, cadence arrows and brackets, and harmonic context across progressions.
What are guide tones and tensions?
Guide tones are the essential tones that define the chord quality and voice-leading function. In many chords, these are the 3rd and 7th. In sus chords, the suspended 4th may function as the structural guide tone.
Tensions are color tones such as 9ths, 11ths, 13ths, altered tensions, and other extensions. Harmony MIDI Visualizer labels these visually so students can see how each note functions inside the chord.
What are upper structures?
Upper structures are recognizable chord shapes built above a base harmony.
For example, a major triad may appear above a seventh chord to create a specific color. Harmony MIDI Visualizer can detect and display these structures, making it easier to explain advanced jazz voicings visually.
Does Harmony MIDI Visualizer show chord-scales?
Yes. Harmony MIDI Visualizer displays the chord-scale associated with the current harmonic context.
This is useful when connecting voicings, tensions, improvisation, and harmonic function. For example, a dominant chord may show Mixolydian, Lydian dominant, altered, or another appropriate chord-scale depending on the context.
Can Harmony MIDI Visualizer show II–V–I progressions and cadences?
Yes. After you provide the harmonic context, Harmony MIDI Visualizer can analyze how chords connect.
For example, if you enter C-7b5 → F7 → Bbmaj7, the app understands the progression and can display cadence arrows and brackets automatically.
What kinds of cadences can Harmony MIDI Visualizer show?
Harmony MIDI Visualizer is designed to show common harmonic movements such as II–V–I progressions, minor II–V–I progressions, backdoor progressions, tritone substitutions, deceptive resolutions, and other functional chord connections.
What files do I need to create a tutorial with Harmony MIDI Visualizer?
For a complete piano tutorial workflow, you typically need your lesson narration, a video of the piano performance, a MIDI recording of that same piano performance, and a final audio render from your preferred piano sampler or plug-in.
The MIDI file should match the piano performance video so the exported Harmony MIDI Visualizer layer can sync correctly in your video editor.
Does Harmony MIDI Visualizer generate the final finished tutorial video?
Harmony MIDI Visualizer exports the theory-aware visual layer.
You still combine that export with your piano video, narration, camera footage, and final audio in a video editor such as Adobe Premiere, Final Cut Pro, or DaVinci Resolve.
Does the exported video include audio?
No. Harmony MIDI Visualizer exports a silent video.
The export is designed to be used as a visual explanation layer in your video editor. You can then sync it with your final piano audio, narration, overhead piano video, and any teacher camera footage.
Why does the exported video leave space at the bottom?
Harmony MIDI Visualizer leaves space at the bottom of the frame so you can place your real piano footage there in your video editor.
This lets you align the real keyboard footage with the animated keyboard visualization and create a polished piano tutorial layout.
What video quality does Harmony MIDI Visualizer export?
Harmony MIDI Visualizer exports a 4K video layer suitable for professional tutorial production.
Can I have a white background?
Yes. Harmony MIDI Visualizer includes a white background option.
You can change the background and other visual options from the Settings menu inside the app.
This is useful when you want a cleaner, brighter tutorial look, or when your final video layout works better with a light background instead of the default dark visual style.
Can I use Harmony MIDI Visualizer without filming my hands?
Yes. You can use the exported visualization by itself, especially for theory explanations, analysis videos, MIDI demonstrations, or course materials.
However, the strongest workflow is to combine it with real piano footage, narration, and high-quality piano audio.
Do I need a MIDI keyboard?
A MIDI keyboard is strongly recommended because the workflow is built around playing harmonic reference chords into the app.
The main source is the MIDI file, but the fastest and most musical way to provide harmonic context is by playing the reference chord on a MIDI keyboard.
What happens if I make a mistake while entering chords?
You can go back and correct the harmonic context.
Use Space or Next to advance. Use Shift–Space or Previous to go back and re-enter a chord if needed.
What happens if the harmony does not change?
Just click Next or press Space without entering a new chord.
Harmony MIDI Visualizer will continue using the previous harmonic context until you provide a new one.
What is an Enhanced MIDI file?
An Enhanced MIDI file is the original MIDI performance with the harmonic context saved inside it.
This lets you preserve the analysis work you added in Harmony MIDI Visualizer and reopen or reuse it later.
Do I have to save the Enhanced MIDI file?
No. Saving the Enhanced MIDI file is optional.
You can save it if you want to keep the harmonic analysis embedded in the file, or cancel if you only need the current export.
Can Harmony MIDI Visualizer fix wrong notes in my performance?
No. Harmony MIDI Visualizer is not designed as a MIDI editor or performance-correction tool.
It analyzes the MIDI notes against the harmonic context you provide. Passing notes, embellishments, and occasional wrong notes can still be shown in context, but the app does not automatically rewrite or correct the performance.
Is Harmony MIDI Visualizer only for jazz?
No, but it is especially powerful for jazz and advanced harmony.
Because it understands chord symbols, chord-scales, tensions, upper structures, and cadential function, it is ideal for jazz piano, reharmonization, standards, film harmony, gospel-influenced harmony, and modern keyboard voicings.
Can I use Harmony MIDI Visualizer for classical music?
Yes, especially if you want to explain harmony, cadences, voice leading, or chord function from a MIDI performance.
The app’s strongest current language is jazz and chord-symbol-based theory, so it is most natural for chord-based educational content.
Can Harmony MIDI Visualizer replace my video editor?
No. Harmony MIDI Visualizer creates the theory-aware visual layer.
You still use a video editor to assemble the final tutorial with narration, camera footage, piano audio, and any additional graphics.
Can I use my own piano sound?
Yes. Harmony MIDI Visualizer’s export is visual only.
For the final tutorial, you can render your MIDI through any piano sampler, virtual instrument, DAW, or plug-in you prefer.
Is Harmony MIDI Visualizer available for Windows or iPad?
Harmony MIDI Visualizer is currently designed for macOS.
We may consider additional platforms in the future depending on demand.
What should I prepare before using Harmony MIDI Visualizer?
The most important step is having a clear lesson plan.
Harmony MIDI Visualizer works best when you already know what you want to teach: the progression, the harmonic concept, the voicings, the chord-scales, or the cadence you want students to understand.
