Db to F is a major third (4 semitones), F to A is a major third (4 semitones). Two major thirds stacked, which splits the octave into three equal parts. The same three keys make an augmented chord on each of its notes, which is why its inversions read as Faug and Aaug.

Dbaug on the guitar

Standard tuning (E A D G B E). Strings run low E on the left to high e on the right, frets downwards; × is a muted string, ○ an open string, and each dot shows the note it sounds, with the root in blue-green. Every shape below has Db as its lowest note.

The barre shapes are movable: an E-shape chord's root is the note under your first finger on the low E string, an A-shape chord's root is the note on the A string. Slide the same grip up or down to play augmented chords on other roots.

Inversions of Dbaug

An inversion puts a note other than the root in the bass. The name is what semicord's chord finder calls those notes played bottom to top; a slash name like C/E means a C chord with E in the bass.
