ChordFrog: Piano Ear Training
Chord Recognition Quiz Game
Free · Designed for iPad. Not verified for macOS.
ChordFrog trains your ear to recognise chords by sound — no instrument or extra gear required. Play audio quizzes anywhere, then connect a MIDI keyboard (USB or Bluetooth) whenever you want hands-on practice on real keys.
PRACTICE MODES
• Leap Quiz — no keyboard needed. Multiple-choice ear training you can do anywhere — on the bus, in a waiting room, whenever you have a few minutes.
• Travel Chords — no keyboard needed. An audio chord reference library; tap any chord to hear it.
• Lily Pad Drill — with a MIDI keyboard. 10-question scored rounds with up to 100 points. Three tries per chord, so every attempt counts.
• Free Pond — with a MIDI keyboard. Play freely and ChordFrog names every chord in real time, including inversions and slash chords.
A MIDI keyboard is optional: Leap Quiz and Travel Chords work entirely on their own, while Lily Pad Drill and Free Pond add hands-on practice when you connect one.
LEVELS
Progress through five stages from beginner to advanced:
• The Campfire — the most common chords in pop and folk music
• The Session — all 12 major and minor chords
• The Gig — dominant 7th and major 7th chords
• The Studio — minor 7th, sus2, and sus4 chords
• The Abyss — everything: diminished, augmented, 7ths, 6ths, and more
CHORD VOCABULARY
Recognises major, minor, diminished, augmented, sus2, sus4, dominant 7th, major 7th, minor 7th, half-diminished, 6th, add9 chords — including inversions and slash chords.
Optional: connect any USB or Bluetooth MIDI keyboard for hands-on drills. Designed for pianists, guitarists, singers, producers, and songwriters who want sharper ears.
Ratings & Reviews
Two stability fixes. Connecting a MIDI keyboard and playing your first notes could make ChordFrog quit unexpectedly — that's fixed. So is a crash when a phone call or alarm interrupted your practice. The pond stays calm no matter what.
