Locrian #2 Mode on Guitar: Notes, Chords & Examples

  • May 21, 2026

The Locrian #2 mode is a dark, tense, and sophisticated guitar mode. It has the unstable bite of Locrian because of the b5, but it sounds smoother and less claustrophobic than regular Locrian because it uses a natural 2 instead of a b2.

You can think of it as a half-diminished sound with a more open, melodic color.

For guitarists, Locrian #2 is especially useful over m7b5, ø7, and minor ii-V-i progressions. It works beautifully in jazz fusion, progressive rock, progressive metal, film-score-style writing, and darker modal songwriting.

It is known as:

  • Locrian natural 2
  • Locrian #2
  • The half-diminished scale
  • The 6th mode of Eb melodic minor

Formula

The interval formula for C Locrian #2 is:

1 2 b3 4 b5 b6 b7

Compared to the natural minor scale:

C natural minor: 1 2 b3 4 5 b6 b7

C Locrian #2: 1 2 b3 4 b5 b6 b7

The big difference is the b5.

Compared to regular Locrian:

C Locrian: 1 b2 b3 4 b5 b6 b7

C Locrian #2: 1 2 b3 4 b5 b6 b7

The natural 2 gives the mode a more spacious, less “crushed” sound than regular Locrian.

Notes in C

The notes of C Locrian #2 are:

C D Eb F Gb Ab Bb

Scale degrees:

  • C = 1
  • D = 2
  • Eb = b3
  • F = 4
  • Gb = b5
  • Ab = b6
  • Bb = b7

The two notes that really define the sound are:

  • D, the natural 2
  • Gb, the b5

That combination gives the mode its strange mix of openness and instability.

The Chord That Defines the Mode

The defining chord of C Locrian #2 is:

Cm7b5(add9) or Cø9

Notes:

C Eb Gb Bb D

This chord captures the mode perfectly because it contains both of the most important color tones:

  • Gb, the b5, gives the chord its half-diminished tension.
  • D, the natural 9, separates it from regular Locrian.

A plain Cm7b5 chord gives you the basic Locrian-family sound:

C Eb Gb Bb

But when you add the D, the chord becomes much more clearly Locrian #2.

That natural 9 is what makes the mode feel smoother, more modern, and more fusion-friendly.

On guitar, try this voicing:

Cm7b5(add9)

E|---10---
B|---11---
G|---11---
D|---10---
A|--------
E|---8----

Notes from low to high:

C Bb Eb Gb D

It sounds dark, but not muddy. The D on top gives it a mysterious, floating quality.

Chord Progressions

Because C Locrian #2 is unstable by nature, it often works best with a C pedal tone, repeated riff, or vamp. If you move through too many chords too quickly, the ear may stop hearing C as the center.

Here are three useful progressions.

Progression 1

Roman numerals:

iø9 – ivm7 – bVII7 – iø9

Chords in C:

Cm7b5(add9) – Fm7 – Bb7 – Cm7b5(add9)

This is a strong fusion-style progression.

The Cm7b5(add9) gives you the modal center. The Fm7 adds a darker minor color, while Bb7 gives the progression some movement without fully resolving to a normal major or minor tonic.

Mood:

  • Dark
  • Smooth
  • Fusion-friendly
  • Great for melodic lead playing

Try soloing with C Locrian #2 over the whole progression, especially if the bass keeps returning to C.

Progression 2

Roman numerals:

iø9 – bVI7 – bVII7 – iø9

Chords in C:

Cm7b5(add9) – Ab7 – Bb7 – Cm7b5(add9)

This one has a bigger, more dramatic sound.

The Ab7 and Bb7 chords are both diatonic to C Locrian #2. They create a dark dominant-chord movement that feels almost cinematic.

Mood:

  • Dramatic
  • Progressive
  • Slightly exotic
  • Good for heavy riffs or soundtrack-style writing

For a heavier guitar approach, try using power-chord shapes with altered bass notes, or keep a low C pedal under the changes.

Progression 3

Roman numerals:

iø9 – bIIIminMaj7 – iiø7 – iø9

Chords in C:

Cm7b5(add9) – Ebm(maj7) – Dm7b5 – Cm7b5(add9)

This is the most “modern” sounding progression of the three.

The Ebm(maj7) chord strongly reveals the melodic minor parent scale color. Since C Locrian #2 comes from Eb melodic minor, this chord sounds very natural inside the mode.

Mood:

  • Mysterious
  • Jazzy
  • Progressive
  • Great for fusion and darker clean-tone sections

This progression works well with extended chords, volume swells, delay, and legato lead lines.

Famous Songs and Guitarists Using C Locrian #2

C Locrian #2 is not a mode with many famous rock or metal songs clearly written in it from start to finish.

That is important to say honestly.

Unlike Dorian, Phrygian, or Mixolydian, Locrian #2 is more commonly used as a chord-scale sound than as the main key center of a song.

You will most often hear it used over m7b5 chords, especially in minor ii-V-i progressions.

For example, in jazz and fusion, a guitarist might use Locrian #2 over the iiø7 chord in a minor key progression.

Common context:

Dm7b5 - G7alt - Cm

Over Dm7b5, many players use D Locrian #2.

That same sound transposed to C gives you C Locrian #2.

Guitarists commonly associated with melodic minor and half-diminished vocabulary include:

  • Allan Holdsworth
  • Frank Gambale
  • Scott Henderson
  • John Scofield
  • Pat Metheny

This does not mean every famous solo by these players is “in Locrian #2.” Rather, these players are strongly associated with the kind of melodic minor language where Locrian #2 naturally appears.

In progressive rock and metal, the sound is less often labeled directly, but the mode’s ingredients — minor 3rd, b5, b6, and b7 — fit well with darker riffs and half-diminished harmony.

If you are writing your own music, C Locrian #2 can give you a sound that feels more unusual than natural minor, but less harsh than regular Locrian.

Guitar Fretboard Shape

Here is a practical C Locrian #2 shape around the 8th fret:

C Locrian #2

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

Notes:

C D Eb F Gb Ab Bb

This shape starts on C at the 8th fret of the low E string.

Pay attention to these important intervals:

  • C to Gb = b5 / tritone
  • C to D = natural 2
  • D to Eb = tense half-step
  • Gb to F = b5 resolving down to 4
  • Bb to C = b7 resolving to root

For a strong modal sound, do not just run the scale up and down. Create phrases that highlight D and Gb.

Why Guitarists Love This Mode

C Locrian #2 gives guitarists a dark sound without becoming completely unusable or overly dissonant.

Regular Locrian can be hard to write with because the b2 and b5 make the tonic feel extremely unstable. Locrian #2 keeps the b5 tension but replaces the b2 with a natural 2, which makes the mode more melodic.

Emotional Flavor

C Locrian #2 sounds:

  • Dark
  • Suspended
  • Mysterious
  • Sophisticated
  • Tense but smooth

It is not as aggressive as Phrygian dominant and not as familiar as natural minor. That makes it great when you want something darker and more unusual.

Riff Potential

The b5 gives you instant riff material.

Try building riffs around:

C - Gb - F - Eb

or:

C - D - Eb - Gb

The first idea emphasizes the tritone. The second idea highlights the natural 2 moving into the minor 3rd, then jumping to the b5.

Both sound great with distortion, especially if you keep returning to a low C.

Soloing Applications

C Locrian #2 works best over:

  • Cm7b5
  • Cm7b5(add9)
  • Cø7
  • Cø9
  • Dark modal vamps
  • Minor ii-V-i progressions
  • Fusion-style changes

It is especially useful if you want a more colorful option over a half-diminished chord.

Instead of playing plain C Locrian, use C Locrian #2 to get a more open, modern sound.

Genres Where It Works Well

C Locrian #2 fits naturally in:

  • Jazz fusion
  • Progressive rock
  • Progressive metal
  • Modern jazz
  • Film scoring
  • Dark ambient guitar music
  • Experimental songwriting
  • Technical metal and fusion solos

It can also work in home production if you want a darker harmonic color for synth pads, guitar layers, or cinematic chord loops.

Tips for Practicing

Practice with a Drone

Put on a low C drone and play the scale slowly.

Do not rush.

Listen to how each note feels against C:

  • D sounds open and spacious.
  • Eb sounds minor.
  • Gb sounds tense and unstable.
  • Ab sounds dark.
  • Bb gives a bluesy minor pull back to C.

Spend extra time on D and Gb. Those are the notes that make the mode speak.

Use Simple Chord Vamps

Start with one-chord vamps before using full progressions.

Try looping:

Cm7b5(add9)

Then improvise using only C Locrian #2.

After that, try:

Cm7b5(add9) - Fm7

or:

Cm7b5(add9) - Ab7 - Bb7

Keep the rhythm simple so your ear can focus on the mode.

Improvise with Small Motifs

Instead of shredding the full scale immediately, create short phrases.

Example motif:

C - D - Eb - D

Then answer it with:

C - Gb - F - Eb

This gives you both sides of the mode:

  • The natural 2 color
  • The b5 tension

Repeat the motif in different octaves and positions.

Target Important Intervals

When soloing, target these intervals:

  • Root: C
  • Natural 2 / 9: D
  • b3: Eb
  • b5: Gb
  • b7: Bb

The most important target note is often D over a Cm7b5 chord. That note turns the basic half-diminished sound into the more colorful Cø9 sound.

For heavier riffs, target Gb.

For smoother fusion lines, target D and Bb.
