The natural minor scale is a seven-note scale running 1, 2, ♭3, 4, 5, ♭6, ♭7 — the major scale with its third, sixth, and seventh each lowered one . It is also the sixth of the major scale: A minor uses exactly the white keys of C major, started from A. The lowered third is what makes it sound minor.
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
The keyboard below is locked to A natural minor. Keys with a green number are in the and play; keys with a red dot stay silent. Press Play. If you know what “minor” sounds like — sadder, darker, more serious than major — this is where that word comes from. It is the second scale most people learn, and the one a great deal of folk, rock, and film music is written in.
2. Counting from home: three flats
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; a (♭) means “that note, one key lower.”
| Degree | Half steps (keys) above the root | In A | What it is |
|---|---|---|---|
| 1 | 0 | A | the root — home |
| 2 | 2 | B | second |
| ♭3 | 3 | C | lowered third — what makes it minor |
| 4 | 5 | D | fourth |
| 5 | 7 | E | fifth |
| ♭6 | 8 | F | lowered sixth |
| ♭7 | 10 | G | lowered seventh |
Three flats: the third, sixth, and seventh. The ♭3 does most of the work — it is the note that makes a scale or a chord sound minor at all. Click a chip to hear each degree in A.
3. Same home, three keys lower: major becomes minor
Start from the major scale on A and lower its third, sixth, and seventh by one key each. Flip the toggle and watch three keys go dark while their lower neighbours light; play both runs. Same root, same shape of walk up the keyboard, and yet the mood has turned. Theory calls this pair parallel: two scales that share a home.
Natural minor keeps every other note but changes 3 (C♯) to ♭3 (C) and 6 (F♯) to ♭6 (F) and 7 (G♯) to ♭7 (G). Flip the toggle and watch 3 keys go dark while their neighbours light up.
Most of the mood lives in one note. Build a chord on the root — 1 3 5, a major — then lower only the middle note to ♭3. Press both. The first is the sound of “major”; the second is the sound of “minor,” and the difference is one key.
4. Same keys, different home: the relative major
Now the other description. Take the seven keys of A minor and, without turning any on or off, call the ♭3 home instead. You are now playing the major scale on C. In A that is C major: the same white keys, settling three keys higher. Flip the toggle and only the green 1 moves.
A natural minor uses exactly the same keys as C major. Nothing turns on or off — only 1 moves. Home is now A, which was the 6 of C major. Play both runs and hear how the same notes settle in a different place.
Theory calls these two relative: they share every key and differ only in where home is. Natural minor is the sixth of the major scale — the major scale started from its sixth degree — which is why its other name is Aeolian. A song can drift between C major and A minor without a single new key appearing; only the note it keeps coming back to tells you which one you are in.
5. The minor that grows two more
Play the scale once more and listen to the last step, ♭7 → 1. It is two keys wide and does not lean toward home. Composers who wanted a stronger arrival raised the seventh one key, and got the harmonic minor — with a wide, dramatic leap between its ♭6 and 7. Raise the sixth as well to smooth that leap out and you have the melodic minor. Both pages open on this root; natural minor is the one the others are measured against.
On a ten-hole harmonica, a C harp played in A is playing A natural minor with no bends needed for the scale itself — fourth position. The Harmonica Lab shows which hole gives each note, for any key of harp.
6. What to do with it
Keep the lock on and play the green keys over a held root. Land on 1, ♭3, or 5 for a settled note; use ♭6 → 5 for the classic minor sigh — one half step, falling. Then turn the root picker to a key with black keys in it and notice that the keyboard shape changes but the sound does not: the scale is the pattern of distances, not the keys.
