This 7-note scale is based on E♭ and includes the following notes:
E♭, G, A, B♭, B, C, D♭
Its interval structure is unusual — it contains five consecutive chromatic tones (A to D♭) yet still allows for functional harmony. The scale resembles the Lydian Dominant mode but deviates with extra chromatic motion and reduced triadic clarity.
Chord Analysis
There are only two perfect 5ths in this scale:
- E♭ to B♭
- C to G
In terms of triads:
- E♭ major is the only full major triad
- C minor is the only minor triad
- There are no 1–4–5 suspended chords available
However, the scale still supports meaningful harmony through 7th chords with no 5th — a useful voicing technique in jazz and modern composition. These omit the 5th (which is often implied) and highlight tensions between the root, 3rd, and 7th.
Chords present in this system include:
- Am7(no 5)
- A7(no 5)
- Bmaj7(no 5)
- Cm7
Audio Example
In the sound clip below, I use a jazzy progression based on this scale:
Cm7 – Bmaj7(no 5) – Cm7/B♭ – A7
This sequence creates a flexible modal base with a tonal center that flirts with Lydian Dominant flavor.

As I’ve explored more complex and obscure scales like this Eb Lydian Dominant variant, I’ve found that a strong understanding of traditional major and minor scale systems is essential. If you’re still developing your theory knowledge, start by learning to spell and memorize the major scales, along with melodic minor and harmonic minor. These three systems form the backbone of most Western music theory.
Even highly altered or chromatic scales — like the one in this article — are typically described in relation to the major scale. Knowing where your scale degrees are coming from (e.g., ♭7, ♯4, ♭6) makes it much easier to analyze harmony and build musical ideas. Without a strong grasp of major and minor functions, it’s easy to feel overwhelmed by the endless options in scale construction. Solid fundamentals give you the tools to explore more freely and with purpose.
