The easiest way to play the minor and major blues scales on jazz guitar is to learn each one as a single shape that repeats in every octave. Keep the root on the same finger every time, and slide one finger through the chromatic notes instead of stretching. For the major blues scale, play the minor 3rd first, move up to the major 3rd, and circle around that 3rd on the way down. This is how Junewon Choi teaches it on VoiceLid Jazz Guitar, and it is one of the first things students in our online jazz guitar lessons learn before using the blues sound over real tunes.
Why Should the Shape Repeat in Every Octave?
On a piano or a saxophone, a scale looks and feels the same in every octave. On guitar, most of us learned scale boxes that change shape every time we move up. That makes the blues sound feel like five different things to memorize. Instead, find a fingering for one octave that you can simply repeat starting from the next root. Take A minor blues: find the A minor triad, put the root under your ring finger, and notice that the next root, one octave up, falls under the same finger in the same pattern. Once you see that, two octaves (and then three) become one idea played twice, not two shapes.
How Do You Finger the A Minor Blues Scale?
Here are the notes of A minor blues: A, C, D, E♭, E, G, A. The blue note is the E♭ between the 4th and the 5th. The fingering rule is simple:
Root: always the same finger (the ring finger in this shape).
Minor 3rd and 4th: stay in position.
4th → blue note → 5th: one finger slides through all three, chromatically.
Minor 7th → root: back to the ring finger on the octave.
The same finger moving through the chromatic notes is what makes the line sound connected. Going up and coming down, the minor blues scale uses the same notes, so you can practice it in both directions without changing anything.
What Changes in the Major Blues Scale?
Now try F major blues. Junewon's version starts like this: root, minor 3rd, major 3rd, 4th, blue note, 5th, minor 7th, root (F, A♭, A, B♭, B, C, E♭, F). Always play the minor 3rd first and then move up to the major 3rd. That small half step is the sound of the blues inside a major chord. Here the chromatic slide is only from the 4th through the blue note to the 5th, again with one finger. Coming down is where the major blues scale is different from the minor one: you never just slide straight down through the 3rds. You circle the major 3rd — touch the notes around it and land on it. Going up, the notes already move in the right direction, so you don't need to think about it.
Where Will You Actually Use These Two Scales?
In a jazz tune, these two shapes are not exercises for their own sake. They line up with the chords. On the live stream this lesson came from, Junewon used them on the standard Sunny: A minor blues over Am7, and F major blues over Fmaj7. The A minor sound already contains the 3rd of the F chord (A), so the two scales connect without a jump. That is the main reason to learn them as clean, repeatable shapes: you can move between them in the middle of a phrase. Wes Montgomery wrote whole tunes on this idea, built on melody and the voicings underneath it, and Wes' Blues Insight opens those tunes one chorus at a time.
How Should You Practice This Week?
Keep it slow and keep it musical:
Play A minor blues for one octave with the ring finger on the root. Repeat it one octave up with the same fingering.
Add a third octave if your guitar allows it.
Play F major blues: minor 3rd to major 3rd going up, circling the major 3rd going down.
Play one bar of A minor blues, then one bar of F major blues, and listen for the A that connects them.
Record yourself and listen back once a day.

What Comes After the Blues Scale?
Once the shapes are in your hands, the next step is hearing how they sit on chords — which notes are chord tones, which are tension, and how one sound moves into the next. That is a voice-leading question, not a scale question, and it is where most self-taught players need a clear path.
