Build the Mixolydian Scale

The name of a Mixolydian scale appears. Your task is to draw its 8 notes on the staff. The Mixolydian scale is the major scale with the 7th lowered by a half step (♭7): it sounds major but with a more open, "modal" ending, common in blues, rock and folk music.

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 Mixolydian scale

The Mixolydian scale follows the pattern W – W – H – W – W – H – W (UK: tone and semitone). It is the same as the major scale except at the end: the 7th is a whole step below the octave (not a half step), because it has been lowered by a half step compared with the major scale.

Mixolydian and the major scale: one accidental apart

Each Mixolydian scale uses the notes of the major scale on the same tonic with one change, the lowered 7th. So G Mixolydian has exactly the notes of C major (no accidentals), and C Mixolydian only adds one B♭. Thinking "major with the leading tone lowered" is the fastest way to build it.

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.

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 Mixolydian scale?
It is the fifth mode of the major scale: a major scale with the 7th lowered by a half step (♭7). Its pattern is W-W-H-W-W-H-W. It keeps the major 3rd (a bright character) but has a minor 7th that gives it a modal sound.
How is the Mixolydian scale different from the major scale?
In one degree only: the 7th. In the major scale the 7th is a leading tone (a half step below the tonic); in Mixolydian it is lowered, a whole step below the octave. Everything else, including the major 3rd, is the same.
How can I build a Mixolydian scale quickly?
Build the major scale on that tonic and lower the 7th by a half step. For example, D major is D-E-F♯-G-A-B-C♯-D; D Mixolydian is D-E-F♯-G-A-B-C-D (C natural instead of C♯).
Why does G Mixolydian have no accidentals?
Because the Mixolydian mode is built on the 5th degree of the major scale, and G is the 5th degree of C major. G Mixolydian uses the white keys: G-A-B-C-D-E-F-G, with F natural as the lowered 7th.
What is the Mixolydian scale used for?
It is basic in blues, rock, jazz and a great deal of folk music. It fits dominant seventh chords (7) and gives a color that is bright and also "unresolved".
