Piano Chord, Scale, Progression Companion for PC

Do you find yourself forgetting chord names or struggling to recall which scales fit together? Piano Chord, Scale, Progression Companion turns your computer into a reference desk for music theory, letting you look up chords by the keys you play, explore thousands of scales, and build progressions without leaving your desk. The app houses over 1500 chords and 10,000 scales (from major and minor to blues and pentatonic) each with fingering diagrams, note layouts, and audio playback so you hear exactly how they sound.

Running Piano Chord, Scale, Progression Companion on a full computer means keeping your reference library open in one window while your DAW, notation software, or practice charts live in others. You stay logged into one machine, access your saved chord charts and custom libraries instantly, and use an external MIDI keyboard to trigger reverse-mode lookups without switching apps. The desktop version eliminates the friction of phone-sized screens and fiddly touch navigation: your real keyboard becomes the input method.

Building Progressions at Your Own Pace

1. Select a starting chord or scale using the Chord Progression Builder
2. View compatible chords within that scale or compatible scales for your chosen chord
3. Experiment with different sequences using relative or common chord patterns
4. Listen to each progression in loop or arpeggiated mode to hear the flow
5. Save successful progressions to your user library for later reference or performance

Reverse Lookup and Custom Chords

The reverse mode solves a common frustration: you play three notes on your MIDI keyboard and the app immediately identifies the chord name and all its variants. If the app doesn't have a chord you need, you can define custom chords and add them to your personal library. This flexibility means Piano Chord, Scale, Progression Companion adapts to your playing style rather than forcing you to match pre-set definitions. Users report that the custom library feature and ability to contribute fingerings make the app feel less like a rigid reference and more like a living tool that grows with your practice.

Theory at Your Fingertips

The Circle of Fifths visualization, available on your larger monitor, helps you understand harmonic relationships without memorizing abstract rules. Piano Chord, Scale, Progression Companion displays each chord and scale on staff notation in both treble and bass clefs, shows analytical labels like Secondary Dominant, and lists relative or similar scales side by side. For beginners and intermediate players returning to music, this built-in tutoring cuts down time spent hunting across multiple websites or textbooks.

One Application, Endless Reference

Piano Chord, Scale, Progression Companion supports external MIDI keyboards, MIDI output for DAW integration, and multiple key notations (English, Italian, German, Japanese, Russian, and others) so musicians worldwide can work in their native harmonic language. The app includes no ads and no forced subscriptions for core features, letting you use the chord and scale reference, fingering diagrams, and progression builder without interruption. Users working within the Chordana piano practice tool space or similar learning environments often pair Piano Chord, Scale, Progression Companion with their main study apps to verify chord names and test progressions before committing them to performance or arrangement.
