Ab Augmented Scale
The Ab augmented scale (also written G#) — Ab B C Eb E G — with its intervals, the chords it fits and every position on the guitar neck.
Also written G# augmented. G# and Ab are the same pitch — Ab is the spelling in common use.
Tap any note on the neck.

Ab augmented scale notes and intervals
Ab 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:
- C augmented — augmented from the 3 — the same six notes again, a major third up
Ab augmented scale positions on guitar — all 6
Ab 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 0 to 15.
Position 1 — frets 4–8
Starts on the 1 (Ab) on the 6th string. Practice this position →
Position 2 — frets 7–11
Starts on the #2 (B) on the 6th string. Practice this position →
Position 3 — frets 8–12
Starts on the 3 (C) on the 6th string. Practice this position →
Position 4 — frets 11–15
Starts on the 5 (Eb) on the 6th string. Practice this position →
Position 5 — frets 0–4
Starts on the #5 (E) on the 6th string. Practice this position →
Position 6 — frets 3–7
Starts on the 7 (G) on the 6th string. Practice this position →
Chords to play Ab augmented over
Ab augmented is the scale for the augmented chord Abaug (Ab C E) and for Abmaj7#5 (Ab C E G), a major 7th with a raised 5th. It is two augmented triads woven together, Abaug and Ebaug (Eb G B), and its steps alternate three frets and one.
Play the Abaug 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 Ab augmented scale
- Start with position 5 at frets 0–4, slowly, until every note lands on the click. The loop keeps the shape and the tempo for you.
- Slide the shape: position 1 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 Abaug arpeggio, the chord’s notes alone, then back to the scale.
- See every Ab augmented note across the whole neck on the Fretboard, and find each box again an octave up.
