Build the Harmonic Minor Scale

The name of a harmonic minor scale appears. Your task is to draw its 8 notes on the staff. It is the natural minor scale with the 7th raised by a half step to create a true leading tone; that raise produces an augmented second between the 6th and the 7th degree.

How to use the exercise: Click (or drag) on the staff to place each note. First choose the accidental with the ♭ ♮ ♯ buttons if the note needs one. Undo removes the last note and Clear restarts the exercise. The notes are sorted automatically from low to high. The magnifier shows the note you are about to place.

The pattern of the harmonic minor scale

The pattern is W – H – W – W – H – A2 – H (UK: tone and semitone; A2 = augmented second). The raised leading tone leaves a distance of three half steps (an augmented second) between the unaltered 6th degree and the raised 7th: the unmistakable sound of this scale.

The raised leading tone and the augmented second

Compared with the natural minor, the harmonic minor raises only the 7th degree. That note is written with a sharp or a natural sign (depending on the key signature) without changing its letter name. Because the 6th stays where it is, the augmented second appears between the two, as in the harmonic major scale but with a minor 3rd.

To lock these scales into your fingers, practice them with the online metronome at 60-70% of your target tempo, raising it by 5 BPM each time you play three repetitions without mistakes. The online tuner lets you check your tuning before you start.

The same exercise on paper, for class: eight harmonic minor scales to write without a key signature, with each accidental before its note. With a separate answer sheet, with the answers in red.

It goes from easier to harder: first key signatures with few accidentals in treble clef, then more accidentals and the bass clef.

Frequently Asked Questions

What is the harmonic minor scale?
It is the natural minor scale with the 7th degree raised by a half step to obtain a leading tone. Its pattern is W-H-W-W-H-A2-H. The raise creates an augmented second between the 6th and the 7th degree.
Why is the 7th raised?
To get a true leading tone, a half step below the tonic, which strengthens the cadence into it. The natural minor does not have one, so its harmonic resolution is weaker.
Where is the augmented second?
Between the 6th degree (unaltered) and the 7th degree (raised). In A harmonic minor it is the leap from F to G♯: three half steps written between two notes with neighboring letter names.
How do I write the raised 7th?
With a sharp if the key signature does not alter the note, or with a natural sign if the key signature had it flat. The letter name never changes: it is still the 7th degree, only raised.
How is it different from the melodic minor scale?
The harmonic minor raises only the 7th and keeps the augmented second. The melodic minor also raises the 6th, to remove that augmented second and smooth the ascent.
