What is the

Let’s dive deeper into Intervals and figure out what the scales are. Scales are a selection of notes, out of the chromatic scale (12 notes). They are constructed using steps.

The relative steps of the minor scale are: w-h-w-w-h-w-w (w=whole step, h=half step).
Let’s explore how that exactly works:

Chromatic intervals

To explain the the minor scale best, take a look at the piano. Especially to the highlighted notes. Those are the notes in the minor scale.


Notice the numbers of the highlighted notes.
Schematically they look like this:

Chromatic intervals for highlighted notes
Note names in chromatic scale (in key of C)

Diatonic intervals

If we would re-number the highlighted notes (instead of using the absolute numbers of the chromatic scale) we create a new interval (scale) that looks like this.


Notice again the numbers of the highlighted notes.
Schematically they look like this:

Diatonic intervals in the minor scale
Notes names for the minor scale (in key of C)

What does diatonic mean?

The term “diatonic” basically means two tones. This refers to the two different kinds of steps that occur in major scales. The term “diatonic” is used to mean “of the scale”. If you’re playing in the key of A major and you’re using A major notes, then the notes you’re using are diatonic. In the example above (with the piano), you saw that only the notes of scale are included, they only have notes “of the scale”.

Step names

The steps of a diatonic scale are known by these names:
  • 1st – Tonic (key note)
  • 2nd – Supertonic
  • 3rd – Mediant
  • 4th – Subdominant
  • 5th – Dominant
  • 6th – Submediant
  • 7th – Leading tone
  • 8th – Tonic (Octave)

Scale degree

Another way to look at the minor scale is using a scale degree, this takes the diatonic intervals of the major scale and tells how the scale is transformed.

The scale degree of minor scale is 1, 2, ♭3, 4, 5, ♭6, ♭7.
The diatonic intervals 367 are flat. Flat means to go down a half step.
If you take a look at the piano again, you’ll notice the black keys correspond to this.

Back to the guitar! You might wonder how this all translates back to your instrument and that might be a bit confusing at first, but please stay tuned. As you just seen, the chromatic intervals for minor scale are 1, 3, 4, 6, 8, 9 and 11. To most people, this is not very useful information. The steps are more important to know. Try to learn that by heart. From there it is way more interesting and practical to look at diatonic scale intervals.

Switch between chromatic/diatonic/notes below to see/learn the relations between them. For convenience, the root note (A) is highlighted.

Exercise Try to play all the highlighted root notes (1) on your instrument! Tap on the fretboard to see if it matches.

♭=half step down, ♯=half step up
w=whole step, h=half step, w=whole and half step

As you might notice, the scales have 7 notes, except for the blues and pentatonic scales.
