Build the Melodic Major Scale

The name of a melodic major scale appears (in Spanish-language theory, the escala mayor mixta secundaria). Your task is to draw its 8 notes on the staff. It is the major scale with the 6th and 7th lowered (♭6 and ♭7): a major scale "softened" by its two lowered upper degrees.

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 melodic major scale

The pattern is W – W – H – W – H – W – W (UK: tone and semitone). Because the 6th and the 7th are lowered together, there is no augmented second (unlike the harmonic major scale): the scale moves by whole steps and half steps.

Two lowered degrees, no augmented second

The melodic major scale keeps the major 3rd but lowers the 6th and the 7th. It is a major scale whose upper tetrachord (the top four notes) has the minor form. It has the same notes as the Mixolydian scale with a lowered 6th, and it differs from the harmonic major scale exactly in having no augmented second.

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 dictionary of keys and scales has the full theory.

The same exercise on paper, for class: eight melodic major 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 melodic major scale?
It is a variant of the major scale in which the 6th and the 7th are lowered by a half step (♭6 and ♭7). Its pattern is W-W-H-W-H-W-W. It keeps the major 3rd but softens the two upper degrees.
How is it different from the harmonic major scale?
The harmonic major scale lowers only the 6th and has an augmented second. The melodic major scale also lowers the 7th, which removes that augmented second and leaves a scale made of whole steps and half steps.
Why does it have no augmented second?
Because lowering the 7th too brings the distance between the 6th and the 7th degree back to a whole step. The augmented second of the harmonic major scale disappears.
How is it related to the Mixolydian mode?
The Mixolydian scale lowers only the 7th; the melodic major scale lowers the 6th and the 7th. It is a Mixolydian scale with its 6th lowered too.
How do I build it step by step?
Start from the major scale on the tonic and lower the 6th and the 7th degrees by a half step, keeping the letter name of each note. The rest stays as in the major scale.
