About Arpeggios, Chords & Triads

Thirds stacked into a chord, and you name what it is. The chord can arrive as a block, all the notes at once, or as an arpeggio running up or down — genuinely different recognition problems: a block chord you hear as a colour, an arpeggio you hear as a shape.

Four levels. Major against minor first, then diminished and augmented join them. Level three adds inversions, so you name the quality and whether it's in root position, first or second. Level four leaves triads behind for seventh chords — major seventh, dominant seventh, minor seventh, half-diminished and fully diminished.

Switch between on staff, where you read the notes, and by ear, where you only hear the chord. The clef is yours — treble, bass, alto or tenor — so the chord shows up where you actually read it.

It's free and needs no account. It runs continuously rather than in rounds, saving your answers to your progress in batches of ten if you're signed in.
