guitar chord
D♭aug
Two major thirds stacked. Symmetrical: every note can be heard as the root.
Written the other way round it is C♯aug — the same twelve keys on a piano, a different piece of notation.

What is true of it
D♭aug is D♭, F and A — 1, 3 and #5 counted from D♭.
The easiest of the 5 fingerings below is x4322x: 4 fingers, held at the 2nd fret.
None of them uses an open string, so this chord moves up the neck unchanged — the same shape 1 fret higher is the chord a semitone above.
2 strings stay silent.
Where its notes are on the neck
The brass dots are D♭, the root. Everything else is a chord tone with its degree printed in it.

An inversion is the same chord with a different note lowest. The name changes to a slash name because the bass is what a listener hears as the foundation.
