A Mixolydian Scale on Guitar — 2 Shapes to Play the Whole Neck
A Mixolydian is one of the seven modes of the major scale — on guitar its notes are A B C# D E F# G, built from the formula 1 2 3 4 5 6 b7. Computed live for this exact root and scale, Fretprism finds 2 repeating shapes — the small pattern set you actually need to play it across the whole neck.

A Mixolydian on the Guitar Fretboard
The notes of Mixolydian repeat across the guitar fretboard in connected positions. Use the shape below to identify root notes, scale degrees, and neighboring shapes.
- Frets 2–9 (span 7 frets)
- Lowest note B, highest note A
- 2 A root notes, on the D string (fret 7), E string (fret 5)
How to practice this shape
- Start on the root — A at fret 7 on the D string. Play up to the highest note in the shape, then back down, staying inside frets 2–9.
- Your hand shifts 4 times as you cross strings: E→A (-2), A→D (-1), G→B (-1), B→E (-1). Those crossings — not the notes — are what this position is really asking you to learn.
- Once it feels automatic, move on to the next of the 2 shapes — together they cover the whole neck, and the same pattern repeats from there.

Diatonic chords
These are the 7 chords built from A Mixolydian's own notes — the ones that will sound like they belong when you're writing a progression, backing a melody, or jamming in this key. The Roman numeral shows each chord's role in the key: capital for major, lowercase for minor, ° for diminished, + for augmented. Not every scale produces a clean chord on every degree — where that happens, we show it honestly instead of forcing a name that doesn't fit.
