Slash Chords
Chord-over-bass notation, explained: how to read it, when it is just an inversion, how to play it, and why it shows up everywhere from hymns to pop to jazz.
What is a slash chord?
A slash chord is a chord symbol written as two parts separated by a slash — for example C/E. The part before the slash is the chord. The part after the slash is the bass note: the lowest note you play. So C/E is a C major chord with E at the bottom, and you say it out loud as “C over E” or “C slash E.”
That is the whole idea: the chord symbol tells you the harmony, and the slash tells you which note sits underneath it. Everything else about slash chords follows from that one rule.
How to read a slash chord
Read it right-to-left, bass first:
- The letter after the slash is a single note — the bass.
- The symbol before the slash is the full chord, stacked above that bass.
G/B → bass note B, chord G major (G–B–D) on top. Dm7/G → bass note G, chord D minor 7th (D–F–A–C) on top. The bass note is the only thing the slash changes — the chord above it is read exactly as you always would.
Two kinds: inversions vs. added bass
The single most useful question to ask about any slash chord is: is the bass note already part of the chord?
1. It’s an inversion
If the bass note is a chord tone, the slash chord is just an inversion — the same notes, rearranged so a different one is on the bottom.
C/E = C major, 1st inversion. C/G = C major, 2nd inversion. Nothing new is added; the chord is simply turned over.
2. It adds a new bass tone
If the bass note is not in the chord, you get a “true” slash chord — a fuller, often suspended or extended colour.
C/D, F/G and Dm7/G all drop a note underneath the chord that was not there before, creating a richer harmony than an inversion would.
How to play slash chords on piano
The hands split cleanly along the slash:
- Left hand plays the bass note (after the slash).
- Right hand plays the chord (before the slash).
For G/B: left hand plays B, right hand plays G–B–D. For D/F♯: left hand plays F♯, right hand plays D–F♯–A. The bass note is always the lowest sound — if your left hand drifts above the right, you have lost the slash chord and you are back to a plain inversion.

| Symbol | Chord | Bass | Type | What it does |
|---|---|---|---|---|
| C/E | C major | E | Inversion (1st) | C major with its 3rd in the bass. |
| C/G | C major | G | Inversion (2nd) | C major with its 5th in the bass. |
| G/B | G major | B | Inversion (1st) | Very common — gives a rising bass G → B. |
| D/F♯ | D major | F♯ | Inversion (1st) | The classic stepwise-bass slash chord. |
| F/A | F major | A | Inversion (1st) | Smooths a IV chord into a walking bass. |
| C/D | C major | D | Added bass | D is NOT in C major — a bright, suspended sound (often a D9sus voicing). |
| F/G | F major | G | Added bass | A G11/dominant-sus colour — common pop pre-chorus chord. |
| Dm7/G | D minor 7th | G | Added bass | A compact way to voice a G13sus / ii–V sound. |
| Am/G | A minor | G | Added bass | A minor over a descending bass (Am → Am/G → …). |
| C/B♭ | C major | B♭ | Added bass | A C7-flavoured colour with B♭ underneath. |
Why musicians use slash chords
Almost every reason comes back to the bass line:
- Smooth, stepwise bass. Writing G → D/F♯ → Em lets the bass walk down G–F♯–E instead of leaping around, which is why D/F♯ is one of the most common chords in pop and worship music.
- Pedal points. Holding one bass note under changing chords (C/G, F/G, G) builds tension over a steady foundation.
- Voice leading. A specified bass keeps the lowest voice moving by small steps from chord to chord — the heart of good harmony.
- Colour. Added-bass slash chords (C/D, Dm7/G) deliver suspended and extended sounds with a symbol that is far easier to read than the “correct” stacked name.
Frequently asked questions
What does C/E mean?
C/E means a C major chord with E as the lowest (bass) note. The part before the slash is the chord; the part after the slash is the bass. Because E is already a note of C major, C/E is simply C major in first inversion.
Is a slash chord the same as an inversion?
Sometimes. Every inversion can be written as a slash chord (C/E, C/G), but not every slash chord is an inversion. When the bass note is NOT part of the chord — like C/D or Dm7/G — you get a true slash chord that adds a new tone underneath rather than rearranging the existing ones.
How do you play a slash chord on piano?
Play the bass note (after the slash) with your left hand and the chord (before the slash) with your right hand. For G/B: left hand plays B, right hand plays G–B–D. The bass note is always the lowest sound.
Why do musicians use slash chords?
Mostly to control the bass line. Specifying the bass note lets you build smooth stepwise bass movement, hold a pedal point, voice-lead between chords, or add colour — all while keeping the chord symbol easy to read. It is a clearer shorthand than figured bass for modern lead sheets.
What is the difference between C/D and Cadd9?
They share notes but stack them differently. Cadd9 places D inside the chord above the root C. C/D puts D underneath as the bass, so D is the lowest note and the harmony reads as a suspended/9 sound over D. Same ingredients, different bass — and the bass changes the feel.
How do I find the bass note of a slash chord quickly?
Read right to left: the letter after the slash is always the single bass note, and the symbol before the slash is the full chord stacked above it. If the bass letter already appears in the chord, it is an inversion; if it does not, it is an added-bass slash chord.
