Eb Half-Whole Diminished Scale

What is the Eb Half-Whole Diminished Scale?

The half-whole diminished scale reverses the diminished pattern, starting with a half step then a whole step. This version is the classic choice for soloing over dominant 7th chords in jazz — it packs in ♭9, #9, #11, and natural 13 tensions, giving you a dense palette of colorful alterations over a single chord. Here's how the Eb Half-Whole Diminished Scale lays out on the fretboard. This scale is enharmonically equivalent to D# Half-Whole Diminished.

Notes and Positions

Dominant-use symmetric scale starting with a half step. On bass, this scale becomes a toolkit for strong roots, passing tones, and melodic fills that still support the groove. Think in root-on-E and root-on-A boxes, then adapt the same notes for 5-string bass when the low B string gives you another root below the pattern. In the key of Eb, the notes are: Eb, Fb, F#, G, A, Bb, C, Db.

How to Use It

You'll often hear it in Jazz, Fusion, and Dominant V chords. A good way to internalize the sound is to sing the root, then sing a few scale degrees before you play them.

Loop a simple drum groove and keep every note locked to the subdivision before adding fills. Use the interactive fretboard above to spot repeats of the same note on different strings and frets.
