Chord Quality Ear Training

Four colours cover most of what you will ever hear: major, minor, diminished, augmented. Add the sevenths and you cover nearly all of the rest. You choose exactly which types are in the pool, so you can drill maj7 against dominant seventh on its own instead of wading through the whole list.

  • Beginner to advanced
  • Any instrument
Start the exercise

A chord sounds, and you name the type. Pick which types come past, then start.

Chord types
After an answer

Got it right? Then it waits for the answer to finish playing and moves on. A miss always waits for you.

Round length

One question per screen, the answer comes with the reason, and nothing is saved anywhere but this browser.

What it asks

You hear a chord and name its type. Not its root, not its inversion, just what kind of chord it is, which is the skill that transfers to listening to actual music.

The question pool

Start with major and minor only. Two answers, and you will be at ninety percent within a week. Then add dominant seventh and major seventh, which is the pair most people confuse for years, and only then the diminished and augmented chords.

How you answer

Buttons with the chord symbols. One chord per screen, always from the same root, so the only thing changing is the quality.

When the round ends

Ten questions, twenty, or no limit at all. The streak counter is there to make you want one more, not to grade you.

When you get it wrong

The correct type lights up with its intervals in semitones. Play it again and listen specifically to the third, which is the note deciding almost everything.
