What is the blues scale on guitar?

The blues scale is a six-note scale built from the minor pentatonic with one added note — the "blue note" (♭5 or #4). In A blues, the notes are A, C, D, E♭, E, G. That extra chromatic passing tone creates the signature bluesy, gritty sound heard in blues, rock, and jazz.

What is the difference between the blues scale and the pentatonic scale?

The minor pentatonic has five notes (1, ♭3, 4, 5, ♭7). The blues scale adds one extra note — the ♭5 (blue note) — between the 4th and 5th, giving it six notes. That single chromatic addition creates the characteristic tension and release of blues music.

Can you play the blues scale over major chords?

Yes! The minor blues scale works over both minor AND major/dominant chords in a blues context. For example, A minor blues scale sounds great over A7 in a 12-bar blues. The clash between the minor ♭3 in the scale and major 3rd in the chord is a defining feature of the blues sound.

What are the 5 positions of the blues scale?

The blues scale has 5 positions (boxes) that span the entire fretboard, just like the pentatonic. Position 1 starts from the root on the 6th string, and each subsequent position shifts up the neck. Learning all 5 lets you solo freely anywhere on the fretboard.

What is the blue note?

The "blue note" is the ♭5 (diminished 5th) added to the minor pentatonic scale. In the key of A, that's E♭ (Eb). It creates a strong dissonance that resolves naturally to either the 4th or 5th, producing the tense, emotional quality that defines blues music.

Is the blues scale the same in every key?

The pattern (intervals) stays the same in every key — only the starting note changes. The formula is always: Root, ♭3, 4, ♭5, 5, ♭7. So in E blues it's E, G, A, B♭, B, D, and in G blues it's G, B♭, C, D♭, D, F.

Should I learn the blues scale or pentatonic first?

Learn the minor pentatonic first. The blues scale is simply the pentatonic with one added note, so once you know the pentatonic shapes, adding the blue note is easy. Most guitarists learn pentatonic box 1, then immediately add the blue note.

How do I make the blues scale sound good?

Don't just run up and down the scale. Use bends (especially bending the ♭3 toward the major 3rd), vibrato on sustained notes, slides into the blue note, and call-and-response phrasing. The blues is about feel and expression, not speed.

Blues Scale Guitar - The Complete Guide

The blues scale is arguably the most important scale for any guitarist who wants to solo. It's the secret weapon behind every great blues lick, rock riff, and soulful bend you've ever heard. The good news? It's just the minor pentatonic with one extra note — the legendary "blue note."

In this guide, you'll learn exactly what the blues scale is, how it differs from the pentatonic, all 5 fretboard positions, and — most importantly — how to make it sound like the blues.

What Is the Blues Scale?

The blues scale is a six-note scale that adds one chromatic "blue note" to the minor pentatonic. Here's the formula:

Degree	Interval	In Key of A	In Key of E
1 (Root)	Unison	A	E
♭3	Minor 3rd	C	G
4	Perfect 4th	D	A
♭5 (Blue Note)	Diminished 5th	E♭	B♭
5	Perfect 5th	E	B
♭7	Minor 7th	G	D

That ♭5 — the blue note — is what gives the scale its distinctive tension. It sits right between the 4th and 5th, creating a chromatic passage that yearns to resolve.

Blues Scale vs Minor Pentatonic

If you already know the minor pentatonic, you're 90% of the way there. Here's the side-by-side comparison:

Scale	Notes	Formula	In A
Minor Pentatonic	5	1 ♭3 4 5 ♭7	A C D E G
Blues Scale	6	1 ♭3 4 ♭5 5 ♭7	A C D E♭ E G

The only difference is that single ♭5 note. In practice, you play the same pentatonic shapes and simply add one extra fret in each position.

Position 1 — The Essential Blues Box

This is the most commonly used blues scale shape. Every blues guitarist starts here. In the key of A, it begins at the 5th fret:

e|--5-----------8--|
B|--5-----------8--|
G|--5----6--7------|
D|--5----6--7------|
A|--5-----------8--|
E|--5-----------8--|
   ↑           ↑
  Root(A)    ♭7(G)

Blue notes (♭5) are on frets 6 of G and D strings

Notice frets 6 on the G and D strings — those are your blue notes. Don't camp on them; slide through them or bend into them for maximum effect.

All 5 Blues Scale Positions

Just like the pentatonic, the blues scale has 5 interlocking positions covering the entire fretboard. Here they are in A blues:

Position 1 (Frets 5–8)

e|--5-----------8--|
B|--5-----------8--|
G|--5----6--7------|
D|--5----6--7------|
A|--5-----------8--|
E|--5-----------8--|

Position 2 (Frets 7–10)

e|--8----9--10-----|
B|--8----9---------|
G|--7----8---------|
D|--7-----------10-|
A|--8----9--10-----|
E|--8----9---------|

Position 3 (Frets 9–13)

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

Position 4 (Frets 12–15)

e|--12---13--------|
B|--13-------------|
G|--12----------14-|
D|--12---13--14----|
A|--12---13--------|
E|--12---13--------|

Position 5 (Frets 14–17 / Frets 2–5)

e|--3----4--5------|
B|--3-----------5--|
G|--2----3---------|
D|--2----3--4------|
A|--3-----------5--|
E|--3-----------5--|

Start by mastering Position 1, then learn Position 2 so you can shift up the neck during solos. Eventually connect all 5 for full fretboard freedom.

Using the Blues Scale Over a 12-Bar Blues

The 12-bar blues is the most common chord progression in blues music. One of the best things about the blues scale is that you can solo over the entire progression with a single key's blues scale.

12-Bar Blues in A

A7A7A7A7D7D7A7A7E7D7A7E7

The classic 12-bar blues. Solo over all 12 bars using the A blues scale.

Yes — the A blues scale works over all three chords (A7, D7, E7). This is one of the unique features of the blues: minor scale over dominant chords creates that raw, expressive tension.

Quick Shuffle in E

12-Bar Blues in E

E7E7E7E7A7A7E7E7B7A7E7B7

Try the E blues scale over this standard blues in E — great for open-string licks.

Minor Blues

A minor blues — the blues scale fits even more naturally over minor chords.

Essential Blues Scale Techniques

The blues isn't about which notes you play — it's about how you play them. These techniques are essential:

1. Bending the ♭3 to the Major 3rd

This is THE blues move. Bend the ♭3 up a half step to the major 3rd. In A blues, that's bending the C (8th fret, high E) up to C#. This ambiguity between major and minor is the heart of the blues sound.

e|--8b9--5---------|
B|--------8--5-----|
G|-------------7---|

Bend 8th fret up a half step, then release into the lick

2. Sliding Through the Blue Note

Don't just fret the ♭5 — slide through it. Approach it from the 4th and slide up to the 5th in one smooth motion. This turns a potentially harsh note into a flowing, expressive phrase.

G|--5--6/7---------|
D|--------5--6/7---|

Slide from 4th through ♭5 to 5th

3. Vibrato

Add vibrato to sustained notes, especially on the root and ♭7. Wide, slow vibrato sounds emotional; fast vibrato sounds intense. B.B. King's "butterfly" vibrato is the gold standard.

4. Call and Response

Play a short phrase (the "call"), then answer it with a complementary phrase (the "response"). This conversational approach is the foundation of blues phrasing — think of your guitar as singing a melody, not running scales.

Blues Scale in All 5 Common Guitar Keys

The pattern is identical in every key — just shift to the root note:

Key	Notes	Pos 1 Starts
A Blues	A C D E♭ E G	5th fret
E Blues	E G A B♭ B D	Open / 12th fret
G Blues	G B♭ C D♭ D F	3rd fret
D Blues	D F G A♭ A C	10th fret
C Blues	C E♭ F G♭ G B♭	8th fret

3 Classic Blues Licks to Learn

Put the scale to work with these essential licks. All are in the key of A blues:

Lick 1: The B.B. King Box

e|--8b10r8--5-----------|
B|-----------8--5-------|
G|----------------7--5--|
D|----------------------|

Classic B.B. King style — bend, release, descend

Lick 2: Blue Note Slide

e|----------------------|
B|----------------------|
G|--5--6/7--5-----------|

A|------------------7-5-|

Slide through the blue note for a smooth, jazzy feel

Lick 3: Turnaround Lick

e|--5--8--5------------|
B|-----------8--5------|
G|----------------7-5--|
D|---------------------|
A|---------------------|
E|-----------------5---|

A classic turnaround phrase for bars 11–12

Bonus: The Major Blues Scale

There's also a major blues scale — less common but equally useful. It adds a ♭3 (or #2) passing tone to the major pentatonic:

Scale	Formula	In A
Major Pentatonic	1 2 3 5 6	A B C# E F#
Major Blues	1 2 ♭3 3 5 6	A B C C# E F#

The major blues scale has a brighter, more uplifting sound. It's perfect over major and dominant chords. Try mixing minor and major blues scales in the same solo for a richer, more dynamic sound — this is what the pros do.
