Faug Chord on Guitar

Faug = F – A – C# (Root, Major 3rd, Minor 6th)

Faug stretches the major triad's fifth up a half step instead of shrinking it, the opposite move a diminished chord makes, producing another symmetrical structure — this one built entirely from major thirds — at guitar's uniquely demanding first-fret barre position.

The triad is F, A, and C# — root, major third, and that same telltale augmented fifth. Guitarists lean on Faug as an altered stand-in for plain F7 wherever the progression is heading toward Bb major anyway, since the sharpened fifth gives that resolution a sharper, more chromatic runway than a plain dominant seventh offers.

How to Practice It

Getting from plain F major to Faug at this fret means adding fingers on the A, D, and G strings, since none of those raised notes overlap with what the barre and open triad already cover — a genuinely wider stretch layered on top of an already unforgiving position. It's worth remembering the chord's built-in symmetry too: the identical shape, unchanged, also names the augmented triads sitting on its other two notes.

Common Progressions

  • Faug – Bb (an altered-dominant resolution, functioning like V+ – I)
  • Gm – Faug – Bb (vi – V+ – I)
  • Bb – Faug – Bb (a chromatic color move around the tonic)
  • Cm – Faug – Bb (ii – V+ – I)

FAQ

How is Faug different from a plain major triad?
Plain F major's fifth is left where a stable perfect fifth naturally sits, while Faug pushes that same note up a half step, and that single change is responsible for the whole chord's unsettled, reaching quality.
Why is Faug also called a symmetrical chord?
Every gap between its three notes measures a major third rather than the usual mix of major and minor thirds a plain triad uses, so the same three pitches read equally well as an augmented triad rooted on any of them.
Where does Faug typically resolve?
It often functions as an altered substitute for F7, resolving the same way that dominant would — down a fourth to Bb major — but with a sharper, more chromatic edge leading into that resolution.
Is Faug harder to finger than plain F major given the first fret?
Yes, somewhat — it needs extra fingers spread across three strings rather than plain F major's more compact spacing, and that wider reach compounds the difficulty of an already demanding low-position barre.
How does the chord's symmetry show up in practice?
Because nothing about the fingering changes, playing this exact shape elsewhere in a chart can equally well be read and named as the augmented triad built on either of its other two notes.
Why are augmented chords less common than diminished ones in guitar music?
Their unusual, unstable color makes them useful mainly as brief altered-dominant color chords rather than passing chords with a single obvious resolution, so they appear more selectively than diminished chords do.
Does Faug ever appear as a passing chord rather than a substitute dominant?
Yes — it sometimes connects two chords a whole step apart chromatically, using the raised fifth as a stepping stone between two more stable harmonies, a technique borrowed from classical voice-leading practice.
