Press Start to begin. A chord appears — play it, then reveal a progression it lives in.
How to use this
This is a free, ad-free, fully client-side tool for internalizing chord shapes through spaced repetition. A chord name appears, you play it, and a new one follows — by timer or by pressing Next.
Beyond the chord itself, every card gives you context:
- A fitting progression — the chord shown in a real harmonic setting (with roman numerals), so you learn where it actually gets used.
- Why it works — the harmonic logic behind that progression in plain language.
- An example run — the arpeggio notes for each chord plus a common playing pattern (Alberti bass, line clichés, ↑↓ arpeggios, guide-tones…). Hit Play to hear the progression as block chords or the run as arpeggios.
Turn on inversions to drill voicings, show piano for a color-coded diagram, or speak name for hands-free practice.
A tip: start with triads at ~15–20 seconds in manual mode, hide the notes, and only peek when stuck. Play the suggested progression a few times before moving on — chords stick faster when you hear them in motion than in isolation.
