Piano Chords With Finger Numbers for Both Hands
Piano chords with finger numbers use a simple code: 1 is the thumb, 2 the index, 3 the middle, 4 the ring finger and 5 the little finger, in both hands. With that code one short chart covers almost every chord shape you will play.

Piano Chords With Finger Numbers for Both Hands
ChordRunner is a browser game that teaches piano and guitar chords: a chord appears on screen, you play it on a real instrument, and your runner jumps.
Play the demoSeventh chords and when to change
For four-note chords like Cmaj7 the usual fingering is 1 2 3 5 in the right hand and 5 3 2 1 in the left. When the gap between two notes is wide, use 4 instead of 3, whatever feels more even. The rule is simple: fingers that touch neighbouring keys should be neighbouring fingers.
Let the hand learn it
Say the finger numbers the first few times, then stop thinking about them and let repetition do the rest. ChordRunner shows the chord tones on screen in its practice mode, with no lives to lose, so you can settle the fingering before moving on to timed rounds on a MIDI keyboard or a piano near the microphone.
The levels in ChordRunner
- Beginner: major, minor, augmented and diminished chords.
- Intermediate: adds sus2 and sus4.
- Advanced: adds 6th, 7th and 9th chords.

Common questions
What are the finger numbers on piano?
Thumb is 1, index 2, middle 3, ring 4, little finger 5, the same in both hands.
What fingers do you use for a C major chord?
Right hand 1 3 5 (thumb on C, middle on E, little finger on G). Left hand 5 3 1 (little finger on C, middle on E, thumb on G).
Which fingers for chord inversions?
Right hand: first inversion 1 2 5, second inversion 1 3 5. Left hand: first inversion 5 3 1, second inversion 5 2 1.
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.
