Playing the Blues Scale on Guitar
The blues guitar scale is often used in blues, country, rock, and even jazz guitar!
It is just like your regular minor pentatonic scale, but the blues scale has an extra note that is used to create tension in a song.
The Blues Scale Formula
The blues scale has six notes/intervals.
The blues scale formula is: 1 – b3 – 4 – b5 – 5 – b7
You can use this formula to make any blues scale. Just choose a root note for your 1, and follow the rest of the blues formula from there!
Notes in the Blues Scale (The Blues Note)
You’re going to be working with the A minor blues scale.
These are the 6 notes in the A minor blues scale:
A – C – D – D# – E – G
The Blues Note
The blues note is the flattened fifth in the blues scale. This is the note that gives the blues scale its name, and separates the scale from minor pentatonic.
The D# note is the blues note in the A minor blues scale.
A minor pentatonic compared to A Minor blues
With the exception of the b5 (D#), the A Minor Pentatonic scale has the same notes as the A Minor Blues scale. This is the same for any blues scale.
Here they are compared:

A Minor Pentatonic Scale Positions PDF
If you don’t already know your A minor pentatonic scale positions, then here’s a PDF with the tabs for all 5 positions!
You’ll want to learn these before you learn the blues scale.
From there you can incorporate the blues note by learning where the b5 (the blues note) is in each shape.
Blues scale positions
These scale position diagrams will help you to understand the intervallic structure of the blues scale.
Make sure you know your 5 minor pentatonic scale positions first, as shown in the section above. Learning their positions will make the blues positions much easier to memorize.
Position 1 is our root position. This is the most commonly used blues position.
The blues note, the b5, is indicated by the blue dot in all five of these positions.
Position 2 represents our major blues shape.
This scale is oftentimes started at the root note on the D string, and played without the Low E and A strings.
You’ll sometimes see this scale referred to as the D shaped blues position because of this.
Position 3 is the only position where you’ll see the blues note in 3 places.
It is also one of the easiest positions to memorize because the blues note is played in the same location on the Low E and High E Strings.
Because of this, you’ll just need to focus on remembering the blues note at the 13th fret of the D string.
Position 4 is actually quite similar to position 1.
Practice this position starting from the root note on the A string. This will help you to see the similarities between this position and position 1.
Once you’ve got it down at the A position you can start to incorporate the notes on the Low E string.
Note: Some blues charts may show the b5 being played on the high E string behind the 5th interval (the 11th fret high E in this case).
This is one of the easiest positions as a standalone minor pentatonic position, so you just need to memorize the positions of the 2 blues notes, and you’ll be good to go!

Transposing the blues scale to new keys on guitar
Like any scale, you can transpose the blues scale, which means to move it to a new position/root note.
The interval structure will remain the same, but your notes will be different.
It’s really easy to do this! Practice by moving your whole first position shape down a half step. This will move you from the A Minor Blues scale to the Ab Minor Blues scale.
See? Wasn’t that easy?
