The beginner’s guide to the piano blues scale

blue scale

Learning the Blues is an integral part of modern music making. The power and influence of the style can be felt in most forms of contemporary popular music and the music carries historical lessons and legacies that are vitally important. Particular scales have emerged out of the music called the Blues scales. Understanding Blues scales is an important access point to playing the music on the piano!

What is the minor blues scale?

The minor blues scale 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. 

The minor blues scale is a variation on the Minor Pentatonic scale with an added flat fifth scale degree. Here is a little review if you are unfamiliar with the Minor Pentatonic scale. 

Minor pentatonic scale

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. 

Seriously, try it! It is somehow ingrained in the human subconscious, especially the first minor third interval.

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.

Just a little change makes a blues scale

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:

Blues scales formula

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 minor blues 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.

Minor blues scale from D

From D, the scale is spelled D – F – G – A♭ – A♮ – C. The blue note in this minor scale is A flat. Check out the diagram below to see it notated:

minor blues scale

Minor blues scale from F

From F, the scale is spelled F – A♭ – B♭ – C♭ – 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!

Minor blues scale from G

From G, the minor blues scale is spelled G – B♭ – C – D♭ – D♮ – F. The blue note in this minor scale is D flat. Check out the diagram below for the finger pattern:

The finger pattern for the G minor blues scale is the same as it was for C and D. This is a common finger pattern for the minor blues scale and you will see it again!

Minor blues scales from A

From A, the minor blues scale is spelled A – C – D – E♭ – E♮ – G. The blue note in this minor scale is E flat. Check out the diagram below for the finger pattern, you will find it familiar:

Ok! Now that you have played through five different positions of the minor blues scales (C, D, F, G, A) you are ready for some exercises! 

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. 

Blues scales with a chord

When you feel comfortable with this, add a chord underneath the scale as notated below:

Challenging blues scales

You can also incorporate other exercises into your practice such as sequences. Check out a three note sequence in the C minor blues Scale below:

Blues scale

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 the four other positions you have learned. 

You can also apply this pattern to any other scales like the piano chromatic scale  you are practicing! 

What is the major blues scale?

The major blues scale is a variation on the blues scale with a major sounding quality as opposed to a minor sounding quality.

Major blues scale and minor pentatonic scale

The major blues scale is a variation on the major pentatonic scale and shares the same addition of the flat fifth scale degree. 

The scale degree formula for the major pentatonic scale is 1 – 2 – 3 – 5 – 6. In the key of C major, this is spelled C – D – E – G – A. Check out this notation below:

Major blues scale formula

All we need to do to transform the C major pentatonic scale into the C major blues scale is add the flat fifth scale degree. 

This means the new formula for the major blues scale will be 1 – 2 – 3 – ♭5 – 5 – 6. In the key of C, we spell this C – D – E – G♭ – G – A. The blue note in this major scale is G flat. Check it out notated below:

Major blues scale

Try substituting the major blues scale for all the exercises you practiced above. How does the major blues scale sound compared to the minor blues scales? 

How do the blue notes differ between the major scale and minor scale? Does the major blues scale sound more happy? Is that even possible?

The twelve bar blues form

Now that you have five positions of the Blues scale under your fingers, it is time to learn a basic Blues form. As the name suggests, the twelve bar Blues is twelve measures in length and consists of three chords: I, IV and V. Check out the form below:

Blues scale

What are all these chords

All the chords in the chart above are dominant 7th chords.

The twelve bar Blues form begins with the I chord, C7 in this example, for four measures, moves to the IV chord, F7 in this example, for two measures, back to the I chord for two more measures and then moves to the V chord, G7 in this example, for one measure, F7 for one measure, and then finally back to the I chord for two measures. 

Measures 9 and 10 are known as the turnaround. There are many, many variations on this form. 

Once you feel comfortable playing through the form, try this exercise with the chords in your left hand and Blues scale in your right hand. You can also use the blues scales to play an arpeggio of the chords in the blues progression.

Scale the blues

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.

Some basic riffs and melodies with the blues scale

Now that you have an understanding of the Blues Scale and form, it is important to learn some basic riffs and melodies in the scale. A common melodic structure in the Blues scale is the call and response. The call and response is essentially an AAB form. A musical phrase is sung or performed on an instrument, with a sort of open ending similar to a question mark. The same phrase is repeated again. Then, a second phrase different from the first two answers the question posed by the first phrase. This is an extremely common and effective phrasing structure and you will hear this influence across many genres of contemporary music. Check out an example of this structure below:

Blues scale

This example is a basic, four measure call and response. The first phrase, G-B♭-C, is repeated twice, followed by the phrase G-B♭-C-B♭-G. You might also see this phrase structure called antecedent-consequent in other realms of music theory.

Now check out this same four measure phrase placed in the context of the Blues form:

Blues scale

When the progression moves to the IV chord, modulate the melody up to match the chord. In this case, the melody begins in the G Blues scale and modulates up to the C Blues scale to match the IV chord. Since the IV chord only happens for two measures, you need to resolve the melody in measures 7-8 with the G Blues scale again to match the I chord. Then, modulate the scale up to match the V chord, in this case D, and then down the match the IV chord again, and then resolve the melody in measures 11-12 with the G Blues scale again to match the I chord. It is not rocket science. It should be fun, not an intellectual exercise. The more you practice it and let the creativity flow, the more connected you will feel to the music!

You can develop this technique infinitely. The Blues has been played for at least 100 years and will hopefully be learned and played for hundreds more. Here is another example of a call and response:

Blues scale

 

Can you identify which Blues scale this melody is from? Can you build the Blues form to match? Can you insert this melody into the Blues scale and modulate and modify it to fit the other chords? Practice this technique until these concepts feel easy and normal to you!

Further listening and research

The Blues is a hugely influential style. There is a direct link from Rock n Roll, RnB, Gospel, Jazz, Funk, Soul, and many other genres to the Blues. The Blues scale and form is at the root of all of this. What research can you do for yourself to better understand this style, context, and history? Here are some ideas:

  • Otis Spann was one of the greatest postwar Chicago Blues pianists. Chicago Blues is a particular style of Blues originally influenced by the urban environment of Chicago in the 1940s and 50s. Because of a handful of record labels including Chess, Paramount, and RCA Victor, Chicago Blues was able to gain commercial notoriety and helped spark the British Blues movement in the 1960s. Check out this video of Otis Spann’s piano Blues

 

  • Ray Charles is one of the most famous musicians of any genre of the last century. His playing and performance style is deeply rooted in the Blues. Check out this video of him performing a slow Blues:

 

  • Fats Domino was one of the original Rock ‘n Rollers. His rhythm piano style is highly influential. Can you hear the influence of the twelve bar blues form in this performance of his tune “Blue Monday”?

 

  • Oscar Peterson was one of the greatest pianists in the history of the piano. If you are not already familiar with his recordings and style, I highly suggest you dive in! Like the pianists mentioned above, his style is deeply rooted in the Blues scale. However, Peterson combined his Blues roots with the harmonic advancements of modern jazz music to create some of the most compelling music ever. Check out this performance of his tune “C Jam Blues” with his famous trio of bassist Ray Brown and drummer Ed Thigpen.

Conclusion

Learning how to play blues scale piano is a crucial part of developing as a pianist and musician. There are so many aspects of the style to learn about, from the different blues scales to progressions, riffs, and iconic melodies – not to mention important social and musical history!
