Chords are the harmonic vocabulary of music. On piano, chords are uniquely powerful: one hand can play rich three- or four-note harmony while the other plays melody — creating a complete musical texture from a single instrument. This guide gives you the 20 most essential piano chords with keyboard diagrams, the formula to build any chord from scratch, and the progressions used in hundreds of songs.
The Chord Formula
Every chord is built from intervals — distances between notes measured in semitones (gap between any two adjacent piano keys including black). Learn the formula and you can build any chord without memorising each individually:
- Major chord: Root + 4 semitones (major third) + 3 semitones above that
- Minor chord: Root + 3 semitones (minor third) + 4 semitones above that
- Dominant 7th: Major chord + minor seventh (10 semitones from root)
- Major 7th: Major chord + major seventh (11 semitones from root)
Essential Major Chords
C Major — C E G
Keys: [C] D [E] F [G]

Essential Minor Chords
A Minor — A C E
Keys: [A] B [C] D [E] Finger: 1 3 5 C natural (vs C# in A major) creates the minor quality.

Keys: [G] A [B] C [D] Eb [F] Finger: 1 2 3 5 Use: resolves powerfully to C major. Essential in jazz and Bollywood.
Cmaj7 — C E G B
Keys: [C] D [E] F [G] A [B] Finger: 1 2 3 5 Use: lush, sophisticated. Jazz, bossa nova, film scores.
Am7 — A C E G
Keys: [A] B [C] D [E] F [G] Finger: 1 2 3 5 Use: soul, jazz, contemporary Bollywood.
Chord Inversions
Inversions rearrange chord notes so a note other than the root is lowest. C major root position = C-E-G. First inversion = E-G-C. Second inversion = G-C-E. Same harmony, minimal hand movement between chord changes. Instead of jumping from C root (C-E-G) to F root (F-A-C), play C second inversion (G-C-E) to F root — the hand barely moves. This is professional voice leading.
Essential Chord Progressions
| Progression | In C Major | Common In |
|---|---|---|
| I–IV–V–I | C–F–G–C | Folk, pop, Bollywood, gospel |
| I–V–vi–IV | C–G–Am–F | Contemporary pop (four-chord song) |
| ii–V–I | Dm–G7–C | Jazz standard foundation |
| i–VI–III–VII | Am–F–C–G | Cinematic Bollywood |

Frequently Asked Questions
C major, G major, F major, and A minor are ideal starting chords — all use primarily white keys. These four chords cover hundreds of songs in C major. After these, add D minor and E minor to complete the core beginner vocabulary.
6–8 chords in C major is enough to play hundreds of songs. For broader repertoire, 15–20 chords across multiple keys is practical. Start in C major and expand gradually as confidence grows.
An inversion rearranges chord notes so a note other than the root is lowest. C major root = C-E-G. First inversion = E-G-C. Second inversion = G-C-E. Inversions enable smoother chord transitions by minimising hand movement — professional voice leading technique.
Both have three notes. Major chords use a major third (4 semitones) above the root; minor chords use a minor third (3 semitones). This single semitone difference transforms emotional quality: major sounds bright, minor sounds darker and more expressive.
Practise each chord shape until automatic, then practise transitions: C to G, C to F, G to Am. Track how many smooth transitions per minute and aim to improve weekly. Apply chords in actual progressions and songs as soon as shapes are stable — musical context builds memory faster.
