How ChordBeam works

Learn harmony from the keyboard outward

Designed for players who want to understand chords faster. ChordBeam puts theory right next to your playing — so you learn from what your hands are already doing, not from abstract diagrams.

1

Connect your keyboard

Plug in a MIDI-compatible keyboard, open ChordBeam in your browser and choose your input method. The app is designed to get you into playing quickly instead of forcing you through a long setup process.

2

Play a chord or voicing

As soon as you play, ChordBeam analyzes the active notes and shows the chord name, inversion clues, note spellings, Roman numeral function and visual feedback on the piano, staff or chord wheel.

3

Use what you learn immediately

Move from recognition to understanding. You can compare voicings, test progressions, study harmony, strengthen ear training and build better instincts for practice, teaching or songwriting.

Who ChordBeam helps

Whether you are just learning triads or already working with extended voicings, ChordBeam gives you a faster way to connect sound, shape and theory.

Songwriters & producers

Capture harmonic ideas fast, check your chord quality and experiment with progressions when you are building verses, bridges, hooks and intros.

Teachers & students

Beyond the live app

A music learning site, not just a utility screen

ChordBeam also includes content pages for learning. You can move from live chord detection into practical reading material on beginner chords, genre-specific harmony, chord progressions, key detection and common theory concepts that musicians actually use.

Frequently asked questions

Common questions about ChordBeam

Do I need a MIDI keyboard?

Yes — ChordBeam reads live MIDI input to identify chords in real time. Any USB MIDI keyboard that your browser can access will work. Most modern keyboards connect with just a USB cable and no drivers required.

Does ChordBeam work in the browser?

Yes. ChordBeam is entirely browser-based — no installation, no app download. It uses the Web MIDI API to read your keyboard input directly. Chrome and Chromium-based browsers have the best compatibility.

Can it help me learn music theory?

Yes. Beyond chord detection, ChordBeam includes beginner guides, chord library pages, genre-specific harmony articles and a theory wheel. You can read about seventh chords, chord inversions or the circle of fifths, then immediately apply what you learned on your keyboard.

Is it useful for beginners?

Absolutely. Beginners often benefit the most from real-time feedback. Instead of memorizing chord names in isolation, you play a shape and see the chord name, notes and harmonic function right away. ChordBeam also includes dedicated beginner guides to support learning step by step.
