The 3 Must-Know Guitar Scales for Blues

There are plenty of scales you can use for blues, but three stand out as absolutely essential.

1. The Minor Pentatonic Scale (Your Blues Foundation)

The minor pentatonic scale is the foundation of blues soloing. It’s the first scale most guitarists learn—and for good reason. It’s simple, it sounds great, and it just works over a 12-bar blues.

Here’s A minor pentatonic in the 5th position:

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

How to Make It Sound More Bluesy

• Phrasing is key. Don’t just play the notes—bend them, slide into them, and add vibrato.
• Target chord tones. Over an A7 chord, emphasize A (5th fret, high E string) and E (5th fret, B string).
• Leave space. Think like a singer—play a phrase, then let it breathe.

2. The Blues Scale (Pentatonic with a Twist)

The guitar scales for blues is just the minor pentatonic with an added ♭5 (the “blue note”). This one note creates tension and resolution, making your solos sound more expressive.

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

How to Use the Blues Scale Effectively

• Don’t overuse the ♭5. It sounds best when used as a passing tone rather than a landing note.
• Play it with a shuffle feel. Blues is all about the groove—let your phrasing reflect that.
• Combine it with the pentatonic. Mix minor pentatonic and blues scale licks to keep things interesting.

3. The Major Pentatonic Scale (For That Sweet BB King Sound)

Most guitarists stick to the minor pentatonic, but the major pentatonic is equally important. It creates a happier, more melodic blues sound—think BB King’s buttery licks.

Here’s A major pentatonic:

e|----------------4----7----|  
B|------------5----7-------|  
G|--------4----6----------|  
D|--------4----7----------|  
A|--------4----7----------|  
E|----------------5----7--|  

How to Use the Major Pentatonic in Blues

• Use it over the I chord. If you’re in A blues, the A7 chord loves the major pentatonic.
• Blend it with the minor pentatonic. This is where the real magic happens—switching between the two gives your solos depth and contrast.
• Think of it as “sweet” vs “sour.” The major pentatonic sounds smooth, while the minor pentatonic adds grit.

Try this: Start a phrase in major pentatonic, then resolve it in minor pentatonic. This creates a call-and-response effect that makes your solos sing.

Taking Your Blues Soloing to the Next Level

Now that you know the essential scales, here’s how to make them sound musical.

1. Learn the “Blues Boxes”

Instead of memorizing the entire fretboard at once, focus on small, comfortable positions (a.k.a. “blues boxes”).

For example, here’s the classic BB King Box (A Major Pentatonic at the 8th fret):

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

This small area is gold for blues licks.

Try bending B (10th fret, B string) up to C#—that’s the BB King sound!

2. Target Chord Tones (The Pro Secret)

Great blues players don’t just run up and down scales—they target notes that match the chords.

For example, over an A7 chord, strong notes to land on are:
✔ A (Root)
✔ C# (Major 3rd, sweetens the sound)
✔ E (5th, stabilizes the melody)
✔ G (Flat 7, adds bluesy tension)

Instead of randomly playing the scale, aim for these notes. You’ll instantly sound more intentional.

---

3. Add Dynamics (Soft vs. Loud)

Most guitarists play at one volume—which makes their solos sound flat.

Instead, use dynamics:
🔹 Play soft, then hit a loud note for impact.
🔹 Mute some notes for percussive effect.
🔹 Use double stops (playing two notes together) for thickness.

Try playing a soft lick, then suddenly hit a strong bend—you’ll feel the difference immediately.
