Ebmadd9 is Eb, Gb, Bb and F — Ebm with the ninth added, and no seventh.
It sounds sharp-edged. The ninth grinding a whole step under the minor third is the edge an m9 softens.

| 1 | ♭3 | 5 | 9 |
Minor tonic — a triad with one colour on it.
Also written Ebm(add9), Ebmin(add9) or Eb-add9. The same chord either way; which spelling you meet depends on who wrote the chart.
Ebmadd9 in 1st inversion puts Gb in the bass instead of Eb, the 3rd of the chord. The notes are the same; what changes is what the bass line does, which is most of why you would reach for it — it lets the lowest voice move by step where the root would have jumped.
