The Faug chord

Think of the Faug as uncanny and lifted, like a chord on tiptoe. The chord is built from F - A - Db, a textbook augmented triad. It does its strongest work in Beatles bridges and James Bond themes, where it tends to lift the line by a half-step. The Faug fits into more keys than most writers expect. All You Need Is Love uses this chord in its famous progression. Voicings on both instruments, theory in plain language, progressions in multiple keys and a handful of real song references are all laid out below.

The theory behind Faug

The Faug chord (F - A - Db) is a augmented triad. Its intervals are root, major third, augmented fifth. Functionally it lives at home in a closely related major key as the passing chord, but you'll also find it in a closely related major key as the passing chord. The chord tends to resolve up a half-step into the next major chord, which is why it shows up in Beatles-style bridges and film music.
