A Mixolydian Mode
The A Mixolydian mode uses the notes of D major, starting on A: A, B, C-sharp, D, E, F-sharp, and G. Let’s look at it on the keyboard and on the staff, with fingering for both hands, and hear what sets it apart from A major.

A Mixolydian mode overview
Visualize the A Mixolydian mode on the piano
On the keyboard, A Mixolydian uses A, B, C-sharp, D, E, F-sharp, and G, with C-sharp and F-sharp on black keys, and A again at the top. These seven notes are the D major scale, started on its 5th note. The notes are shared, but the home note is A, and that changes how the scale sounds.
What gives A Mixolydian its sound
Compared with the A major scale, only one note changes: the 7th is G instead of G-sharp. With the 7th a whole step below the tonic rather than a half step, there’s no leading tone pulling upward. The mode is major, but it sounds relaxed and unhurried, with less urgency to resolve.
Its home chord, built on A from the 1st, 3rd and 5th notes, is A major (A, C-sharp, and E). Playing that chord before and after the scale helps the ear hear A as home rather than D.
Play A Mixolydian on the piano
The two charts show the fingering one hand at a time. Each hand covers the seven notes in two positions, a group of three fingers (red) and a group of four (blue); a note in green is an extra note at the end of the scale, outside the two positions.
The right hand starts on A with the thumb. Going up, the thumb passes under to D after the 3rd finger on C-sharp. The top A is played with the 5th finger. This is the same fingering as C major (1 2 3 1 2 3 4 5), which fits here because every note the thumb plays is a white key.
The left hand starts on A with the 5th finger. Going up, the 3rd finger folds over the thumb from E to F-sharp. The top A is played with the thumb. This is the same fingering as C major (5 4 3 2 1 3 2 1), which fits here because every note the thumb plays is a white key.
The notes of A Mixolydian on the staff
On the staff, the eight notes climb by step from A to A, the right hand in the treble clef and the left hand an octave lower in the bass clef. A Mixolydian is written with the key signature of D major: two sharps (F-sharp and C-sharp). The key signature belongs to D major, but here the line begins and ends on A, and that’s what makes it A Mixolydian.
Play A Mixolydian up and down one octave
Next, A Mixolydian as we’ll practice it: up one octave and back down, one note per beat, ending on a half note. The fingering for the right hand is written above the notes and for the left hand below.
Practice A Mixolydian
The fingering is not the difficult part here, since it follows a scale we already know. What tends to go wrong is the ear: the notes of A Mixolydian are familiar from D major, and the scale easily slips back toward D. Let’s work on it in a few stages.
- Find the home note first: Before the scale, we play the A major chord and let it ring, then play the scale and end on the same chord. The aim is to keep A as the center the whole way through.
- Compare with A major: We play the A major scale and then A Mixolydian, slowly, listening for G where A major has G-sharp. That one change is the whole difference in sound, and hearing it is more useful than any rule about the mode.
- Hands separately, then together: Each hand alone first, slowly and evenly, with special attention to the thumb passing under to D in the right hand. Then hands together, an octave apart, keeping the pulse even.
- Shape the line: Once it’s steady, we let the scale grow a little toward the top and relax on the way down. It turns the scale into a phrase and keeps the ear involved.
Avoid common mistakes in A Mixolydian
A few things tend to go wrong in A Mixolydian:
- Hearing D as home: Because the notes are those of D major, the ear tends to treat D as the center and A as a passing note. Starting and ending firmly on A, and playing the A major chord around the scale, keeps the mode’s own center clear.
- Falling back to A major: Out of habit, the hand often plays G-sharp instead of G. Slowing down at that point and naming the note before playing it usually fixes it within a few repetitions.
- Uneven thumb notes: The thumb plays on its side and tends to land heavily, especially right after passing under. Letting the thumb travel early and arrive lightly keeps the line even.
