Piano Chord Inversions Explained

Chord inversions allow you to play the same chord in different positions on the keyboard.

What Are Chord Inversions?

A chord inversion is simply a rearrangement of the chord notes so that a note other than the root is in the bass (lowest note). The same chord can be played in multiple positions, each with a different note on the bottom.

For a triad (three-note chord), there are three possible positions:

  • Root position — The root note is in the bass
  • First inversion — The third is in the bass
  • Second inversion — The fifth is in the bass

Root Position

In root position, the root note is the lowest note. For example, C major in root position is played as C-E-G, with C at the bottom. This is the most stable and common position.

On our chord diagrams, the root position shows the notes stacked from the root upward.

First Inversion

In first inversion, the third of the chord moves to the bass. For C major, this means playing E-G-C (with E at the bottom). The chord is written as C/E (read as "C over E").

First inversion chords sound slightly less stable than root position but still consonant. They are commonly used to create smooth bass lines that move step by step.

Second Inversion

In second inversion, the fifth of the chord is in the bass. For C major, this means playing G-C-E (with G at the bottom). The chord is written as C/G (read as "C over G").

Second inversion is the least stable triad position and is often used as a passing chord rather than a destination. The 6/4 chord (second inversion) has special rules in classical harmony.

Seventh Chord Inversions

Seventh chords have four possible positions:

  • Root position — Root in bass (e.g., C-E-G-B)
  • First inversion — Third in bass (e.g., E-G-B-C), written Cmaj7/E
  • Second inversion — Fifth in bass (e.g., G-B-C-E), written Cmaj7/G
  • Third inversion — Seventh in bass (e.g., B-C-E-G), written Cmaj7/B

Why Learn Inversions?

Understanding inversions is important for several reasons:

Smoother Voice Leading

When changing between chords, using inversions allows you to minimize the distance each finger moves. Instead of jumping your whole hand, you can keep common notes and move other notes by step.

For example, going from C to F: instead of C-E-G jumping to F-A-C, try C-E-G moving to C-F-A (first inversion of F). The C stays the same, E moves up to F, and G moves up to A.

Better Bass Lines

Inversions allow you to create melodic bass lines that move smoothly. Instead of the bass jumping around, it can move step by step or in small intervals.

More Interesting Arrangements

Using different inversions adds variety to your playing. Playing every chord in root position can sound monotonous, especially when accompanying other musicians.

Slash Chord Notation

Inversions are written using slash notation: the chord name followed by the bass note. For example:

  • C/E = C major, first inversion (E in bass)
  • C/G = C major, second inversion (G in bass)
  • Dm/F = D minor, first inversion (F in bass)
  • G7/D = G dominant 7, second inversion (D in bass)

Practice Tips

  1. Play each chord in all inversions, going up and down the keyboard.
  2. Practice common progressions using inversions for smoother voice leading.
  3. Try playing a melody in the right hand while using inversions in the left hand accompaniment.
  4. Listen to recordings and identify when inversions are used.
