Build Shapes
Hear a chord and build it on your instrument. The root is given, so the work is hearing the quality — major or minor, and later the tetrad types — and placing the rest: basic shapes first, then the useful ones, then the inversions.

What you're practicing
A chord is several notes at once — a root and the intervals above it — and the way its notes sit on an instrument is a voicing. The major and minor triads are about 80% of the chords in popular music, and they differ by one semitone: the third.
Build Shapes is the app's chord flashcard. A chord sounds, its root is shown, and the work is hearing the quality — major or minor — and placing the rest: the basic shapes first, then the useful spread ones, then the inversions. Any root, or the triads of a key by degree, which connects harmony to melody and lets you find a progression's chords anywhere. Then the loop: a progression plays, each chord's shape lit as it sounds — nothing to answer, play over it.
On the piano: four octaves, C2 to C6. The 5 exercises above are the loop with the chords decided — the panel still offers every setting, and a link carries yours.
