A Persian Scale on Guitar — 2 Shapes to Play the Whole Neck
A Persian is a named exotic or world scale, independently verified against real theory sources before being added to Fretprism's library — its notes are A Bb C# D Eb F G#, from the formula 1 b2 3 4 b5 b6 7. Computed live for A, it resolves to 2 repeating shapes across the neck.

A Persian on the Guitar Fretboard
The notes of Persian repeat across the guitar fretboard in connected positions. Use the shape below to identify root notes, scale degrees, and neighboring shapes.
- Frets 4–13 (span 9 frets)
- Lowest note G#, highest note F
- 3 A root notes, on the E string (fret 5), D string (fret 7), B string (fret 10)
How to practice this shape
- Start on the root — A at fret 5 on the E string. Play up to the highest note in the shape, then back down, staying inside frets 4–13.
- Your hand shifts 2 times as you cross strings: A→D (+2), G→B (+3). 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 3 chords built from A Persian'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.
