What is the blues scale?
Firstly, there is not just one ‘blues scale’, there are two: a major and a minor variation. Odds are when someone says to you “play a blues scale”, what they mean is play the minor version, so it will come first here.
Blues scales are very common in music. They are found all over the world, in music on the radio and classical music. The important thing to remember is that both of these major and minor variations are based off of pentatonic scales, with a flat 5th added, making each scale have six notes total.

How to play the minor blues scale
The minor blues scale piano is a six note scale that has emerged from Blues music. It has a powerful, soulful, and often melancholic timbre. It is used across many styles of music including traditional twelve-bar Blues, Boogie-Woogie, Soul, RnB, Jazz, and Funk to name a few. This scale is a variation on the minor pentatonic scale with an added flat fifth scale degree.
Minor pentatonic scales explained
The minor pentatonic scale is a five note scale. It is a common piano scale that is found in many music cultures across the world. If you randomly ask someone on the street to sing a five note scale, chances are they will sing the minor pentatonic scale.

The minor pentatonic scale follows the scale degree formula 1 – ♭3 – 4 – 5 – ♭7. To play the minor pentatonic scale from C on the piano, follow the diagram below. The finger numbers for the minor pentatonic scale are notated beneath the notes.
To transform the minor pentatonic scale into the minor blues scale, all you need to do is add in the flat fifth scale degree to the minor pentatonic scale. In the key of C minor pentatonic, that means you will add the note G♭. Check out the diagram below to see this new scale notated.

The formula for this new minor blues scale is 1 – ♭3 – 4 – ♭5 – ♮5 – ♭7.
In vocal styles, the pitch of the flat fifth scale degree is bent up and down for added inflection, expressive power, and emotional impact. However, in tempered pitched instruments with unbending intonation, the flat fifth scale degree cannot be manipulated in the same way.
We also call this flat fifth scale degree the blue note. Adding the blue note to the minor is your gateway to the blues.
Playing the minor blues scale in multiple positions
Can you use the formula and finger pattern you just learned to move the minor blues scale around the piano? Try to use your knowledge to build the scale from D, F, G, and A. Remember, the formula is 1 – ♭3 – 4 – ♭5 – ♮5 – ♭7, or the minor pentatonic scale with an added flat fifth scale degree.

- From F, the scale is spelled F – A♭ – B♭ – B – C♮ – E♭. The blue note in this minor scale is C flat Check out the diagram below to see it notated:Notice the change in finger pattern here. Instead of your first finger on the third note, you continue with your fourth finger and land with your first finger on C♭. Practice this different finger pattern until you feel comfortable.Remember, practicing with proper piano technique and fingering means greater technique, control, and creativity down the road!
- From G, the minor blues scale is spelled G – B♭ – C – C# – D – F. The blue note in this minor scale is D flat.

First, play through all five patterns in a row, beginning with C, followed by D, F, G, then A and returning to C again one octave higher.
How to play the major blues scale
The major blues scale is a variation on the scale with a major sounding quality as opposed to a minor sounding quality.

Try substituting the major blues scale for all the exercises you practiced above. Pay attention to how the major blues scale sounds compared to the minor blues scales. Also make sure to note how the blue notes differ between the major scale and minor scale.
Playing the major blues scale in multiple positions
Because we know that all of our major blues scales are being pulled from the major pentatonic scale, and we know that they all have the same formula, we can learn a lot of them very quickly! Remember to think about the music in scale degrees, 1 – b3 – 3 – 5 – 6. Let’s try it in a bunch of different positions!
- From D, the scale is spelled: D, E, F, F#, A, B, D
- From F, the scale is spelled: F, G, Ab, A, C, D, F
- From G, the scale is spelled: G, A, Bb, B, D, E, G
- From A, the scale is spelled: A, B, C, C#, E, F#, A
Exercising the blues scales
You can incorporate some exercises into your practice such as sequences. Practice playing your piano chords. Check out a three note sequence in the C minor blues scale below:
This sequence pattern is a great exercise to practice to gain dexterity and flexibility with the minor blues scale. You can apply this pattern to any other scales like the piano chromatic scale you are practicing!
Get comfortable playing through the blues form in quarter notes. Practicing this will build your fluidity with these shapes and help develop your ears. There are a few points of tension and release that you should become comfortable with.
The first is the transition in and out of the IV chord in measures 5-7 and the second is the turnaround, the V-IV-I progression in measures 9-12. These points act as springboards in the form.
You can use these points to build up tension in your improvisation or as release or resolution points.
Once you feel comfortable with the form in C, modulate the progression to D, F, G, and A.
- In the key of D, the I, IV, and V chords are D, G, and A.
- In the key of F, the I, IV, and V chords are F, B♭, and C.
- In the key of G, the I, IV, and V chords are G, C, and D.
- And in the key of A, the I, IV, and V chords are A, D, and E.
