Chord Inversions & Slash Chords

The same three notes can sound completely different depending on which one sits at the bottom. That's the whole idea behind chord inversions.

What is a chord inversion?

A triad has three notes: root, 3rd, and 5th. Normally the root sits at the bottom — that's called root position. An inversion reorders those same three notes so a different one is the lowest, or "bass," note.

Reading slash chords

A slash chord spells out an inversion directly in the chord symbol: C/E means "play a C major chord, but put E in the bass." That's exactly C major in first inversion. Slash chords are the fastest way to notate an inversion on a lead sheet or chord chart.

💡 Why bother? Inversions smooth out bass lines. Moving from a C chord to an F chord sounds more connected as C → F/A → G than jumping straight between root-position chords — the bass note steps gradually instead of leaping around.

Common questions

What is a chord inversion?

A voicing where a note other than the root is in the bass — the same three notes, reordered.

What is first inversion vs second inversion?

First inversion puts the 3rd in the bass; second inversion puts the 5th in the bass. Root position has the root in the bass.

What does a slash chord like C/E mean?

The letter before the slash is the chord; after is the bass note. C/E means C major with E in the bass — first inversion.

Why use chord inversions?

They create smoother bass lines and more varied voicings, letting chords connect naturally instead of always jumping to the root.
