The root left to the bass player. Frees a finger for a tension.
Eb13 is Eb, G, Bb, Db, F and C — Eb9 with the thirteenth added on top.
It sounds big and open. Six notes will not fit under four fingers: the fifth goes first, then the ninth, and the third, flat seventh and thirteenth stay.

| Eb | G | Bb | Db | F | C |
|---|---|---|---|---|---|
| 1 | 3 | 5 | ♭7 | 9 | 13 |
Dominant — the full V chord.
Also written Ebdom13 or Eb dominant 13. The same chord either way; which spelling you meet depends on who wrote the chart.
Leave the root to the bass player. In a band nobody misses it, and the ear supplies it from the guide tones anyway.
The finger it frees goes to a tension, which is why these sound richer than the shape they came from rather than thinner.
Eb13 has 24 of them, on the middle four strings, the top four strings and strings 5-3-2-1, from open position up to the 11th — every inversion the chord has: G in the bass, Bb in the bass, Db in the bass, F in the bass and C in the bass. The one to learn first is the C shape at the 2nd fret, which is the easiest grip here.
8 of them sit on the middle four strings, so you can run the inversions up one set without changing strings — which is the whole reason to learn them as a family rather than as separate grips.
Start with x65688 — no barre and low, at the 5th fret. None of the shapes for Eb13 uses an open string, so every one of them is movable; the lowest sits at the 5th fret. 6 of the 8 need a barre. Together they cover the neck from the 5th fret to the 13th.

Tensions. A shell of Eb13, root, third and seventh, leaves a string free, and the tones that belong over it are the #11 (A).
Eb13 is the V of Ab, and that is where it goes if it goes anywhere: the third and the flat seventh are a tritone apart, and both resolve by a semitone into Ab.
Voice by voice, Eb13 → Ab. 2 voices move by a semitone, and 2 notes are common to both chords.
| In Eb13 | Moves | In Ab |
|---|---|---|
| Eb, the root | stays where it is | Eb, the fifth |
| G, the major third | rises a semitone | Ab, the root |
| Bb, the fifth | falls a whole tone | Ab, the root |
| Db, the flat seventh | falls a semitone | C, the major third |
| F, the ninth | falls a whole tone | Eb, the fifth |
| C, the thirteenth | stays where it is | C, the major third |

On Eb13’s sound and use this page follows Ted Pease & Ken Pullig, Modern Jazz Voicings (Berklee Press, 2001). The shapes and the derived voicings come from different places, and both are explained in where the chords and the theory come from.
