Eb7(b9) — dominant flat ninth

Also written D#7(b9) — the same chord, spelled the other way.

Notes in Eb7(b9): Eb – G – Bb – Db – FbFormula: 1 – 3 – 5 – b7 – b9

In the formula, the numbers count steps of the major scale starting from the note that names the chord; "b" lowers a half step, "#" raises one — and a slash names the bass note.

The 7(b9) is a dramatic dominant. The minor ninth intensifies the resolution, especially when the target chord is minor.
