Chordra

NEW Quiz Mode update! Learn chord tones on virtual piano. Master chords through random progressions, not finger patterns. Build skills that work in any situation.

Ever thought "I definitely know how to play this chord..."?

The reason why a chord that felt natural in one song suddenly feels awkward in another is because you didn't truly master the chord itself—you just memorized the finger patterns.

Chordra mixes your selected chords randomly, so you can build real chord skills instead of just pattern memorization.

• Find the chords you need Choose the chords you struggle with most. Quickly select the chords you want to work on with smart filters for root, triad, 7th, extensions, and alt/add.

• Save your favorites Create your own chord presets for tomorrow’s practice, or start with built-in major and minor diatonic sets.

• Learn on the go No piano around? Use the virtual piano quiz mode to test your chord tone knowledge—perfect for the bus, subway, or anywhere.

• Loop Mode for Tough Progressions Loop and repeat any chord progression until it feels natural and effortless.

• Practice Settings Customize beats per chord, BPM, and number of chords displayed on screen.
