Dbaug Guitar Chord
Db Augmented · also written C#aug · Db–F–A
Dbaug is the Db augmented chord: Db–F–A. Its sound is dreamlike and unsettled — the raised 5th makes it float, perfect for transitions. It's also written as C#aug — same notes, same shapes, different spelling.
Dbaug raises the 5th of Db major by a half-step, splitting the octave into equal major 3rds. Like the diminished chord it's symmetrical — the same shape three frets up spells another augmented chord. Songwriters use it to lift from I toward IV or vi (think the intro of "Oh! Darling").
The most common way to play Dbaug is the augmented grip at the 9th fret (9 x 11 10 10 9, low E string to high E string). Below you'll find 3 ways to play it across the neck, from open position to barre and shell voicings, with the theory behind the chord and the progressions it lives in.
