Every chord type from major triads to dominant 13ths — with formulas, voicing tips, and sound character.
9 modes across all 12 keys — diatonic chords, formula, emotional context, and related scales.
From jazz ii–V–I to gospel and pop — theory, examples in C, and practical uses.
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.
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.
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.
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.
When you play a chord, ChordBeam surfaces every relevant piece of information about it.

Every pitch class active in your chord, spelled clearly
The lowest note — tells you if a chord is in root position or inverted
