An inversion is the same chord with a different chord tone in the bass.

A standard C chord has C as its lowest note — that’s root position. Move the chord so E is in the bass and you’ve got first inversion, usually written C/E. Move it so G is in the bass and you’ve got second inversion, usually written C/G.

The notes are still C, E, and G. The chord is still C. What changed is the lowest note.

How to think about it

Take a triad — a three-note chord built from a root, third, and fifth. For C, that's C, E, and G.

For a triad, there are three positions:

• Root position — root is the lowest note. C in the bass.
• 1st inversion — third is the lowest note. E in the bass. Often written C/E.
• 2nd inversion — fifth is the lowest note. G in the bass. Often written C/G.

Larger chords can have more inversions. A seventh chord, for example, can also have the seventh in the bass:

• C7 in root position has C in the bass.
• C7/E has the third in the bass.
• C7/G has the fifth in the bass.
• C7/Bb has the seventh in the bass.

The chord usually keeps the same basic identity in your progression. What changes is the way it sounds, how settled it feels, and the bass note that connects it to the chords before and after.

Inversions vs slash chords

Inversions are often written as slash chords, but not every slash chord is an inversion.

A slash chord tells you which note should be in the bass. For example:

• D/F# means play a D chord with F# in the bass.
• C/G means play a C chord with G in the bass.

Those are inversions because F# belongs to a D major chord, and G belongs to a C major chord.

But some slash chords use a bass note that is not part of the chord. For example, C/D means a C chord over a D bass note. That is still a slash chord, but it is not technically an inversion because D is not one of the notes in a basic C chord.

The simple rule:

• Bass note is part of the chord → inversion.
• Bass note is outside the chord → slash chord, but not an inversion.

Why you'd use one

Three reasons inversions matter:

1. Smoother bass lines. A bass line that walks up or down by step usually sounds better than one that leaps. If you're moving from C to F, putting E in the bass first — C/E — lets the bass move C → E → F instead of jumping straight from C to F.
2. Less hand movement. Sometimes the inverted shape sits closer to the next chord than the root-position version. Fewer position shifts mean smoother changes.
3. A different colour. A C/G with G in the bass can sound more open, more lifted, or less settled than a thick root-position C. That can be useful when you want a progression to feel like it is still moving rather than fully resolved.

You’ll hear inversions everywhere in pop, folk, rock, gospel, classical music, and film music. They are often the difference between a flat-sounding chord chart and a part that feels like it is going somewhere.

Finding inversions in Fretscape

Open the Filters panel and look under Shape & Sound. The Inversions and Bass Note filters are both part of Pro.

• Inversions Inversions lets you filter by chord-position type, such as Root, 1st, and 2nd. For chords with more notes, Fretscape can also understand deeper inversion relationships where the bass note is another chord tone.
• Bass Note lets you choose the exact lowest note you want. This is fully chromatic, so you can pin any bass note — not just notes that are already part of the chord.

Use Inversions when you care about the chord’s internal position: root in the bass, third in the bass, fifth in the bass, and so on.

Use Bass Note when you care about the actual note at the bottom. This is useful for slash chords like D/F#, where you want Fretscape to show voicings of D with F# as the lowest note. It also works for non-inversion slash chords, where the bass note is outside the chord.

For example:

• To find C/E, search for C and set the bass note to E.
• To find D/F#, search for D and set the bass note to F#.
• To explore a non-standard slash sound like C/D, search for C and set the bass note to D.

If you want to compare a chord across inversions, set Difficulty to your level and toggle between inversion options to see how the same chord appears in different places on the neck. Tap the play button on a card to hear it, and you’ll feel why one bass note might fit a particular spot in your progression better than another.
