Ab/Eb Guitar Chord
Ab/Eb is the second inversion of Ab, built from Eb, Ab, C with Eb as the lowest sounding note. It contains the same pitches as Ab. The slash notation specifies that Eb sounds in the bass instead of the root. It places Eb in the bass under Ab major, used in the keys of Ab and Db. The Eb bass connects naturally to the Db or Bb chord, and Ab/Eb appears in gospel and classical progressions where a sustained fifth pedal tone is desired under the Ab harmony.

Notes in the Ab/Eb Chord
Ab/Eb is the second inversion of Ab. It contains 3 notes: Eb, Ab, C. These are the same pitches as Ab, but with Eb as the lowest sounding note. Because the notes are identical to Ab, Ab/Eb carries the same harmonic colour. The distinction lies in the bass: changing which note sits lowest reshapes the voicing and enables smoother bass-line movement between chords.
What Does Ab/Eb Mean?
In chord notation, a slash chord is written as Chord/Bass — the letter before the slash is the chord to play, and the letter after the slash is the specific note that should sound as the lowest pitch. For Ab/Eb, this means: play Ab with Eb in the bass.
Because Eb is the fifth of Ab, Ab/Eb is specifically called the second inversion of Ab. An inversion does not change the notes in the chord. It only changes which note sits at the bottom, which affects how the chord sounds in context and how smoothly it connects to the chords around it.
Guitarists use slash chords primarily for smooth bass-line movement. Instead of the bass jumping from root to root between chords, a well-placed slash chord creates a stepwise (scale-like) bass line that makes a progression feel connected and natural. This technique is borrowed from classical voice leading and is used across every genre of modern music.
