Reading Chords on the Staff at a Glance
Chords on the staff are easier to read than single notes once you see the shapes. A root position triad is three notes stacked on three lines in a row or three spaces in a row, like a small snowman. Name the bottom note and you know the chord.

Line chords and space chords (treble clef)
- C major: C on the ledger line below, then E and G on the two lowest lines.
- E minor: E, G, B on the three lowest lines.
- G major: G, B, D on lines 2, 3 and 4.
- F major: F, A, C in the three lowest spaces.
- A minor: A, C, E in spaces 2, 3 and 4.
Major or minor? Look at the sharps and flats
D major and D minor look the same on the staff, D F A, except for one sign: D major needs F#. The shape tells you the root, the accidentals (or the key signature) tell you if it is major or minor. In C major with no sharps or flats, D F A is D minor.

Play the demoInversions on the staff
When the snowman breaks, it is an inversion. First inversion has two notes close together at the bottom and a gap at the top (E G C). Second inversion has the gap at the bottom (G C E). Find the note right above the gap: that is the root.
Read chords on a real staff in the game
A ChordRunner sight reading option writes chord symbols above a melody, like a real lead sheet, and prints each chord as stacked notes on a bass staff below. You play along on a MIDI keyboard or a piano near the microphone, and each chord turns green when every note was right.

Common questions
How do you read chords on the staff?
Look at the shape. Three notes on consecutive lines or consecutive spaces form a root position triad, and the bottom note is the root. Then check sharps, flats and the key signature to see if it is major or minor.
How do major and minor chords look different on the staff?
Often they look identical except for one accidental on the middle note. D major is D F# A, D minor is D F A.
How do I find the root of an inverted chord on the staff?
Look for the gap of a 4th between two notes: the upper note of that gap is the root. In E G C, the gap is between G and C, so the root is C.
Which instruments work?
A USB MIDI keyboard, detected automatically, or a piano or guitar through the microphone. Everything runs in Chrome or Edge on a computer, tablet or phone.
How is this different from apps where you tap the screen?
Tapping trains your eyes and fingers on glass. Here you press real keys or fret real strings, and the game hears the actual notes, so what you practise is exactly what you will play on your instrument.
