The minor is a five-note scale — counted from the , 1, ♭3, 4, 5, ♭7. Every note sits at least two keys from the next, so nothing clashes, which makes it the first solo scale most players learn. Add one more key, the , and it becomes the blues scale.
The five-note column is older than the blues — a West African pentatonic sense of pitch that traveled into work songs, field hollers, and spirituals. In the southern United States it became the skeleton of blues and rock solos; pin a flattened fifth onto it and you have the blues scale.
This page is a lesson, not a poster. Read it top to bottom; every section has something to press, and the whole page follows one root and one octave — change either and everything below changes with it. If the low keys are hard to hear on your speaker, use Octave + to lift the whole lesson.
1. First, hear it: five notes
A is a short list of the twelve piano notes that a piece treats as home. Most scales pick seven. This one picks five — penta is Greek for five — and it is the scale more people have soloed on than any other. Almost every rock guitar lead, most blues licks, and a great deal of folk melody from several continents sits inside it.
The keyboard below is locked to A minor pentatonic. Keys with a green number are in the scale and play; keys with a red dot stay silent. Press Play, then press the green keys in any order you like, fast or slow. Notice that you cannot make it sound wrong. That is the whole point of the scale, and section 3 explains why.
2. Counting from home: the five degrees
Every scale has a home note, the — here A, and the picker above moves it. The other notes are named by how far above the root they sit: their . Count keys to the right, black and white alike; each key is one . The plain numbers 1 to 7 belong to the major scale, the ruler everything else is measured with. A (♭) in front of a number means “that note, one key lower.”
| Degree | Half steps (keys) above the root | In A | What it is |
|---|---|---|---|
| 1 | 0 | A | the root — home |
| ♭3 | 3 | C | lowered third — what makes it minor |
| 4 | 5 | D | fourth |
| 5 | 7 | E | fifth |
| ♭7 | 10 | G | lowered seventh |
Two of the five are lowered. The ♭3 is what makes the scale minor — in A it is C, one key below where the major scale would put its third. The ♭7 follows it. And two of the major scale’s degrees are simply not here: no 2, no 6. Click a chip to hear each degree in A.
3. Why nothing clashes
Look at the gaps between neighbours. 1 to ♭3 is three keys. ♭3 to 4 is two. 4 to 5, two. 5 to ♭7, three. ♭7 back to the octave, two. Every gap is at least a whole step. There is not a single half step anywhere in the scale — no two notes sit on adjacent keys.
Half steps are where friction lives. Two notes one key apart rub against each other; a melody that lands on one usually has to move to the other. The major scale has two such pairs and natural minor has two, and a beginner who lands on the wrong side of one hears a “mistake.” The minor pentatonic has none. Whatever note you land on, its neighbours are far enough away that it can sit there. Press the two runs below: the first is the scale, the second walks up all twelve keys in a row. Hear how much rougher the second is.
4. Where the five come from: natural minor, two notes removed
Start from the seven-note natural minor scale in A — 1 2 ♭3 4 5 ♭6 ♭7. Now remove the two notes that create its half steps: the 2, which sits one key below ♭3, and the ♭6, which sits one key above 5. What is left is the minor pentatonic. Flip the toggle and watch two keys drop out; play both and hear the seven-note scale smooth into the five.
Minor pentatonic is natural minor with 2 (B) and ♭6 (F) removed — flip the toggle to see them come back.
That is a useful way to think about any pentatonic: a seven-note scale with its trouble spots taken out. It is also why the scale is so forgiving over a chord progression — the notes most likely to clash with a passing chord are exactly the ones that are not there.
5. Same keys, different home: the major pentatonic
Now the map view. Take the five keys of A minor pentatonic and, without turning any on or off, call the ♭3 home instead. You are now playing the major pentatonic on C — 1 2 3 5 6, bright and open, the scale of a great many folk tunes and country licks. In A that is C major pentatonic: the same five white keys, settling somewhere brighter. Flip the toggle and only the green 1 moves.
A minor pentatonic uses exactly the same keys as C major pentatonic. Nothing turns on or off — only 1 moves. Home is now A, which was the 6 of C major pentatonic. Play both runs and hear how the same notes settle in a different place.
Guitarists lean on this constantly: the fingering they learned for A minor pentatonic is, unchanged, C major pentatonic — they just treat a different note as the place to land. The relationship is the same one that links the major scale to its relative minor, three keys down.
6. Add one key: the blues scale
The pentatonic’s one weakness is also its charm: with no friction anywhere, it can sound a little too safe. The blues fixes that by squeezing one extra key in between 4 and 5 — the ♭5, in A the key E♭. Six keys apart from the root, wedged against two neighbours, it is the one note in the scale that cannot sit still. Flip the toggle and hear the five become the blues scale.
Minor pentatonic is blues scale with ♭5 (E♭) removed — flip the toggle to see it come back.
7. Where it comes from
Five-note scales are not owned by anyone. Versions of this shape turn up in Scottish and Irish tunes, in Chinese and Japanese music, in Andean flute melodies, and across West and Central Africa. The line that matters most for the music on this site runs through the last of those: the ethnomusicologist Gerhard Kubik traces the pentatonic habits of pitch in West African song into the work songs, field hollers, and spirituals of the American South, and from there into the blues. The blues scale — this scale plus its — is where that lineage is easiest to hear. Where did the blues come from? tells the longer version.
8. What to do with it
Keep the lock on and play. With the lock on there are no wrong notes, so stop thinking about which key and start thinking about rhythm and shape — short phrases, a rest, a reply. Land on 1 to finish a thought and on 5 to leave it open. Pick the root that matches your song; guitar blues and rock usually live in A or E. When the five start to feel too polite, go to What is the blues scale? and add the sixth note.
