F# Augmented Scale
The F# augmented scale (also written Gb) — F# A A# C# D F — with its intervals, the chords it fits and every position on the guitar neck.
Also written Gb augmented. Gb and F# are the same pitch — F# is the spelling in common use.

F# augmented scale notes and intervals
F# augmented has 6 notes. Each is named by its distance from the root, which is the same in every key — learn the numbers once and every augmented scale reads the same.
Step pattern from the root: W+H – H – W+H – H – W+H – H (W is a whole step, two frets; H is a half step, one fret; W+H is three frets).
Scales it shares notes with:
- Bb augmented — augmented from the 3 — the same six notes again, a major third up
F# augmented scale positions on guitar — all 6
F# augmented fits in a five-fret box, three notes or two on each string. Its steps alternate three frets and one, so the six positions are two shapes: positions 1, 3 and 5 are one, 2, 4 and 6 the other, and moving either one four frets up or down gives the same six notes again. Together they cover frets 1 to 14.
Position 1 — frets 2–6
Starts on the 1 (F#) on the 6th string. Practice this position →
Position 2 — frets 5–9
Starts on the #2 (A) on the 6th string. Practice this position →
Position 3 — frets 6–10
Starts on the 3 (A#) on the 6th string. Practice this position →
Position 4 — frets 9–13
Starts on the 5 (C#) on the 6th string. Practice this position →
Position 5 — frets 10–14
Starts on the #5 (D) on the 6th string. Practice this position →
Position 6 — frets 1–5
Starts on the 7 (F) on the 6th string. Practice this position →
Chords to play F# augmented over
F# augmented is the scale for the augmented chord F#aug (F# A# D) and for F#maj7#5 (F# A# D F), a major 7th with a raised 5th. It is two augmented triads woven together, F#aug and C#aug (C# F A), and its steps alternate three frets and one.
Play the F#aug arpeggio inside the scale → The Practice Loop keeps only the chord’s notes in each position, so you hear what the rest of the scale is decorating.
How to practice the F# augmented scale
- Start with position 6 at frets 1–5, slowly, until every note lands on the click. The loop keeps the shape and the tempo for you.
- Slide the shape: position 2 is the same fingering 4 frets higher, and the same notes. Play one, then the other, and the move is the scale.
- Climb 3 notes at a time, two notes up each time: each group starts a major third above the last, the same step the scale repeats by.
- Switch the same position to the F#aug arpeggio, the chord’s notes alone, then back to the scale.
- See every F# augmented note across the whole neck on the Fretboard, and find each box again an octave up.
