What is a chord inversion?
A chord's notes can be stacked in different orders. When the root is the lowest note, the chord is in root position. When another chord tone is at the bottom, the chord is inverted. The notes are exactly the same, so it is still the same chord, but it sounds a little different and sits differently under your fingers.
Here is C major (C E G) in all three positions. The lowest note, shown in purple, decides the inversion:
How to tell the inversion
Ignore the order of the upper notes and look only at the bass note:
| Bass note | Inversion | C major | Slash chord | Figured bass |
|---|---|---|---|---|
| C (root) | Root position | C E G | C | 5/3 |
| E (3rd) | 1st inversion | E G C | C/E | 6 |
| G (5th) | 2nd inversion | G C E | C/G | 6/4 |
Seventh chords have four notes, so they have a fourth position: the seventh in the bass is third inversion (for example Cmaj7/B, or B C E G). The figured bass names for sevenths are 7, 6/5, 4/3 and 4/2.
Slash chords
Chord symbols use a slash to show the bass note: C/E means a C major chord with E in the bass, which is first inversion. C/G is second inversion. A slash can also name a note that is not in the chord (like C/D), but inversions are the most common use. Reading slash chords is a good test of whether you know your inversions, so Heavy lift includes them.
Why inversions matter
- Smooth chord changes. Moving from C to F in root position means every finger jumps. Play F in second inversion (C F A) and the C stays put, so only two fingers move by a step.
- Better sound. Voices that move by small steps sound connected, instead of the whole hand leaping.
- Walking bass lines. First inversions let the bass move by step (C, then C/E, then F) while the harmony stays the same.
- Emotional colour. Root position is solid and stable, first inversion is lighter, and second inversion feels unsettled and pulls toward the next chord.
Want the smoothest hand movement for a whole song? The smooth chord changes tool picks the best inversion for every chord in your progression and shows the fingering.
How to practise inversions
- Start with C major. Play all three positions up the keyboard: C E G, then E G C, then G C E, then C E G an octave higher.
- Name the bass note first. Before you play, say which chord tone is at the bottom. That is the inversion.
- Learn them in a few keys. The Warm-up level uses only white-key chords. Add sharps and flats in the Working set.
- Build them from scratch. The "build" questions ask you to place the notes yourself, which is the real skill at the keyboard.
- Use them in a progression. Try C, F, G, C with inversions so your hand barely moves.
If you are new to the keys, start with the piano key trainer. To spell chords correctly, see the chord finder, and to see every chord in a key, the chord chart.
Frequently asked questions
What is a chord inversion?
An inversion is the same chord with a different note at the bottom. C major is C E G in root position. Moving C to the top gives E G C (first inversion), and moving E up as well gives G C E (second inversion). The notes are the same; only the order changes.
How do I know which inversion a chord is in?
Look only at the lowest note. If it is the root, the chord is in root position. If it is the third, first inversion. If it is the fifth, second inversion. For seventh chords, the seventh in the bass is third inversion.
What does C/E mean?
A slash chord. The letter before the slash is the chord (C major) and the letter after it is the bass note (E). C/E is therefore C major in first inversion.
Why use inversions on piano?
They let you move between chords with very little hand movement. Instead of jumping to the next root-position chord, you pick the inversion whose notes are closest to the chord you are already holding, which sounds smoother and is easier to play.
Which inversion sounds the most stable?
Root position, because the root is in the bass. First inversion sounds lighter and is often used to connect chords or walk the bass. Second inversion has the least stable sound and tends to pull toward the next chord.
How many inversions does a chord have?
A triad has three positions (root and two inversions). A seventh chord has four (root and three inversions).
