The third voice from the top lowered an octave. The dropped voice becomes the bass, which is why a string is skipped.
Ebm9 is Eb, Gb, Bb, Db and F — Ebm7 with the ninth stacked above it.
It sounds warm, and considerably richer than an m7. The standard voicing for a ii chord once the plain one has been played enough.
Pre-dominant or minor tonic — an m7’s job with more colour.

| Eb | Gb | Bb | Db | F |
|---|---|---|---|---|
| 1 | ♭3 | 5 | ♭7 | 9 |
Also written Ebmin9, Eb-9 or Eb minor 9. The same chord either way; which spelling you meet depends on who wrote the chart.
The same operation one voice further down: the third voice from the top falls an octave and becomes the bass.
That leaves a bigger hole under the top three notes, so a string gets skipped: the muted string in the middle is the shape, not a mistake.
Ebm9 has 7 of them, on strings 5-3-2-1 and strings 6-4-3-2, from the 2nd fret up to the 11th — every inversion the chord has: Eb in the bass, Gb in the bass, Db in the bass and F in the bass. The one to learn first is the Eb shape at the 2nd fret.
4 of them sit on strings 6-4-3-2, 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.
Five notes and four fingers, so something has to go. Keep Gb and Db (they fix the quality) and F (what the symbol is about). Let Bb and Eb go, in that order — a perfect fifth says nothing the root has not, and in a band the bass has the root.
Play Ebm9 as a shell — root, third and seventh — and the spare string takes the 11 (Ab) or the 13 (C).
All 7 common shapes as fret numbers, lowest string first. Hover or tap one to see it drawn.
How you get to it. The turn that lands on Ebm9 is Fm7♭5 to Bb7♭9: the ii and the V of Eb minor, which is where a minor tonic is usually arrived at rather than simply begun on.
In which keys. Every note of Ebm9 belongs to C# major (the ii, the supertonic), Eb minor (the i, the tonic), F# major (the vi, the submediant) and Bb minor (the iv, the subdominant).
Every note of Ebm9 is in Eb dorian and Eb natural minor.
Change one note of Ebm9 and you have Ebm69 (the flat seventh becomes the sixth), Ebm7 (drop the ninth), Ebm11 (add the eleventh), EbmMaj9 (the flat seventh becomes the major seventh), Ebmadd9 (drop the flat seventh) or Eb9 (the minor third becomes the major third).
Ebm9 is a minor chord — root, minor third, fifth. Minor chords on every root.
The common shapes and the derived voicings come from different places, and both are explained in how this site is built.
