Piano Chord Chart (Chord Notes and Keyboard Diagram)

Find the notes of any chord on the piano. Choose a root and a chord type, or type a symbol such as Bbmaj7, F#m7b5 or C/E, and the chart shows the notes, the intervals, which keys to press (with octave numbers), the inversions and a simple two-hand voicing, plus a keyboard diagram you can download. A table lists every chord type on the same root for quick comparison.

How to use this tool

1. Choose the root note and the chord type, or type a chord symbol.
2. Read the notes and intervals, and the keys to press (middle C is C4).
3. Pick an inversion for the diagram if you want the chord in another position.
4. Try the two-hand voicing, and download the keyboard picture if you like.

Formula

Chord tones = root + intervals: major 0 4 7, minor 0 3 7, 7 = 0 4 7 10, maj7 = 0 4 7 11, m7 = 0 3 7 10 semitones

Notes are spelled by scale step, so every 3rd is two letters above the root: B♭maj7 is B♭ D F A and F♯m7♭5 is F♯ A C E. In root position the tones are stacked upwards from the root; each inversion moves the lowest note up an octave, so C E G becomes E G C (1st inversion) and G C E (2nd). The voicing puts the root and its 5th in the left hand and the other tones close together just above middle C in the right hand.

Example

Dm7 is D F A C (intervals 1, ♭3, 5, ♭7). In root position press D4 F4 A4 C5; for two hands, play D3 A3 with the left hand and C4 F4 A4 with the right. B♭maj7 is B♭ D F A, pressed as B♭3 D4 F4 A4.
