Locrian Dominant Mode on Guitar: Notes, Chords & Examples

  • May 21, 2026

Locrian Dominant is a dark, tense, unstable mode with a strong dominant chord sound.

It has the bite of Locrian because of the b2, b5, and b6, but it also has a major 3rd and b7, giving it a dominant 7th quality. That combination makes it sound mysterious, aggressive, and exotic.

For guitarists, this mode works especially well over:

  • Dominant 7b5 chords
  • Dark fusion vamps
  • Progressive metal riffs
  • Cinematic tension sections
  • Exotic rock and metal songwriting

It is not a “happy” or “resolved” sound. Locrian Dominant wants to lean, grind, and create tension.

What Is Locrian Dominant?

Locrian Dominant is the 5th mode of Neapolitan Minor.

But you do not need to think about the parent scale to use it musically.

The important sound is this:

A dominant chord with a flat 5, surrounded by dark altered color tones.

Compared to C Mixolydian, C Locrian Dominant changes several notes:

C Mixolydian:

C D E F G A Bb

C Locrian Dominant:

C Db E F Gb Ab Bb

So you still get the dominant core:

C E Bb

But the surrounding notes are much darker:

  • Db = b2 / b9
  • Gb = b5
  • Ab = b6 / b13

That gives the mode its tense, sinister sound.

Formula

The interval formula for C Locrian Dominant is:

1 b2 3 4 b5 b6 b7

Using interval names:

P1 m2 M3 P4 d5 m6 m7

This is the key to the mode’s personality.

The major 3rd gives it a dominant flavor, while the b2, b5, and b6 make it feel unstable and dark.

Notes in C

C Locrian Dominant contains the notes:

C Db E F Gb Ab Bb

Or spelled as scale degrees:

C  Db  E  F  Gb  Ab  Bb
1  b2  3  4  b5  b6  b7

On guitar, pay special attention to these notes:

  • C = root
  • E = major 3rd
  • Gb = flat 5
  • Bb = flat 7
  • Db = flat 2 / b9

Those are the strongest notes for creating the mode’s identity.

The Chord That Defines the Mode

The defining chord of C Locrian Dominant is:

C7b5

The notes are:

C E Gb Bb

This chord captures the mode because it includes:

  • C = root
  • E = major 3rd
  • Gb = b5
  • Bb = b7

That gives you a dominant chord, but with an unstable tritone-based color from the b5.

A practical guitar voicing:

C7b5

e|---x---
B|---5---  E
G|---3---  Bb
D|---4---  Gb
A|---3---  C
E|---x---

You can also think of the full modal color as:

C7b5(b9, b13, add11)

That comes from adding the other notes of the mode:

Db = b9
F  = 11
Ab = b13

But for practical guitar use, C7b5 is the clearest home base.

Chord Progressions

Because C Locrian Dominant is unstable, it often works best with vamps, pedals, and riffs rather than traditional functional progressions.

Keep returning to C7b5 or a C pedal tone so the ear understands C as the center.

Progression 1: Dark bII Vamp

Roman numerals:
I7b5 - bIImaj7 - I7b5 - I7b5

In C:
C7b5 - Dbmaj7 - C7b5 - C7b5

This is one of the clearest ways to hear the mode.

The Dbmaj7 chord emphasizes the b2 sound, which is one of the darkest colors in the scale. Moving from Dbmaj7 back to C7b5 creates a tight half-step pull.

Mood:

  • Dark
  • Suspenseful
  • Exotic
  • Great for fusion or prog intros

Try playing a low C drone underneath the whole progression for extra tension.

Progression 2: Progressive Metal Movement

Roman numerals:
I7b5 - ivm - bV - bII

In C:
C7b5 - Fm - Gb - Db

This progression leans into the mode’s heavy guitar potential.

The move from C7b5 to Fm gives a dark minor sound, while Gb highlights the b5 as a full chord root. The Db chord brings back the b2 color.

Mood:

  • Heavy
  • Cinematic
  • Tense
  • Good for progressive metal or dark rock sections

For a riff version, try using low-string power chord shapes but replace normal fifths with tritones when you want more Locrian Dominant bite.

Progression 3: Exotic Fusion Vamp

Roman numerals:
I7b5 - bVI+ - bVIIm - I7b5

In C:
C7b5 - Ab+ - Bbm - C7b5

The Ab+ chord is especially colorful because it contains:

Ab C E

That chord brings out the b6 while still keeping the major 3rd of C in the harmony.

The Bbm chord gives a darker minor movement before resolving back into C7b5.

Mood:

  • Exotic
  • Fusion-oriented
  • Slightly disorienting
  • Great for odd-meter vamps

This one works well with clean delay guitar, legato phrasing, or atmospheric production.

Famous Songs and Guitarists Using C Locrian Dominant

C Locrian Dominant is an advanced synthetic/modal sound, and there are not many famous guitar songs that are clearly and universally identified as being written in this exact mode.

So it is better not to force fake examples.

Unlike modes such as Dorian, Phrygian, Lydian, or Mixolydian, C Locrian Dominant does not have a large list of well-known rock songs built directly around it.

However, the sound is commonly associated with musical areas such as:

  • Jazz fusion dominant chord vocabulary
  • Altered dominant improvisation
  • Progressive metal tension riffs
  • Exotic film-score harmony
  • Modern modal composition

Guitarists who explore related altered dominant and exotic modal sounds include players such as:

  • Allan Holdsworth
  • John McLaughlin
  • Frank Zappa
  • Steve Vai
  • Joe Satriani
  • Guthrie Govan

That does not mean a specific famous song by these players is “in C Locrian Dominant.” Rather, their music often uses the kind of advanced harmonic tension where this mode can fit naturally.

A very practical use is improvising over chords like:

C7b5
C7b5(b9)
C7b5(b13)
C7b5(b9, b13)

In that context, C Locrian Dominant becomes a strong choice.

Guitar Fretboard Shape

Here is a practical C Locrian Dominant shape around the 8th position.

Notes:

C Db E F Gb Ab Bb

Tab-style fretboard diagram:

e|-------------------------8-9-12-13-|
B|------------------9-11-13----------|
G|------------9-10-11----------------|
D|------8-10-11----------------------|
A|-8-9-11----------------------------|
E|-8-9-12----------------------------|

Root notes C are found at:

E string: 8th fret
D string: 10th fret
B string: 13th fret
e string: 8th fret

Start by resolving your phrases to C, E, Gb, or Bb.

Those notes outline the defining C7b5 sound.

Why Guitarists Love This Mode

C Locrian Dominant is not a basic “campfire chord” mode. It is a tension machine.

That is exactly why creative guitarists love it.

Emotional Flavor

The mode sounds:

  • Dark
  • Dangerous
  • Exotic
  • Unresolved
  • Mysterious
  • Aggressive

The b2 gives it a Phrygian-like darkness, while the b5 creates instability. The major 3rd keeps it from sounding purely minor, which makes the mode feel more unusual.

It is neither standard major nor standard minor.

That ambiguity is powerful.

Riff Potential

For riffs, the most important intervals are:

C to Db = b2
C to E  = major 3rd
C to Gb = b5
C to Bb = b7

Try building riffs around:

C - Db - C - Gb
C - E - Gb - F
C - Bb - Ab - Gb
C - Db - E - C

On guitar, the half-step between C and Db is great for tight, aggressive riffs.

The tritone between C and Gb gives you an instant metal/fusion edge.

Soloing Applications

C Locrian Dominant is excellent over dominant flat-five chords.

Use it over:

C7b5
C7b5(b9)
C7b5(b13)
C7b5(b9, b13)

For soloing, do not just run the scale up and down.

Instead, target the chord tones:

C E Gb Bb

Then use the color tones for tension:

Db = dark b9
F  = suspended 11
Ab = heavy b13

A simple phrase idea:

C - Db - E - Gb - F - E - C

That phrase clearly shows the b2, major 3rd, and b5.

Genres Where It Works Well

C Locrian Dominant can fit beautifully in:

  • Progressive metal
  • Jazz fusion
  • Experimental rock
  • Dark cinematic scoring
  • Modern metal
  • Instrumental guitar music
  • Avant-garde songwriting
  • Tension-heavy electronic production

It is especially useful when you want a dominant sound that feels more dangerous than Mixolydian.

Tips for Practicing

1. Practice Over a C Drone

Start with a simple C drone.

You can use:

  • A looped low C note
  • A synth drone
  • A clean guitar sustain
  • A bass pedal tone
  • A looper pedal

Then slowly play:

C Db E F Gb Ab Bb C

Listen carefully to each note against the C drone.

Focus on how these intervals feel:

  • Db against C = very tense
  • E against C = dominant/major color
  • Gb against C = unstable tritone
  • Ab against C = dark b6
  • Bb against C = dominant b7

This is the fastest way to internalize the mode.

2. Use Simple Chord Vamps

Do not start with complicated harmony.

Try vamps like:

C7b5 - Dbmaj7
C7b5 - Fm
C7b5 - Gb
C7b5 - Bbm

Loop one vamp for several minutes and improvise only with C Locrian Dominant.

The goal is to make the mode sound intentional, not random.

3. Improvise With Small Cells

Instead of playing the whole scale, create small 3- or 4-note cells.

Examples:

C Db E
C E Gb
E Gb Bb
Bb Db C
Ab Gb E C

Move these around rhythmically.

This works especially well for progressive metal and fusion because the intervals are already tense.

4. Target the Defining Intervals

The most important tones are:

1  3  b5  b7
C  E  Gb  Bb

These outline C7b5.

Then add:

b2 = Db
b6 = Ab

Use Db and Ab as tension notes. Resolve them into chord tones for stronger phrases.

For example:

Db -> C
Ab -> Gb
F -> E

These small resolutions make the mode sound musical instead of just “outside.”

Try This Mode in SLModes
