D Augmented

The first shape is the easiest voicing: 4 fretted strings and 0 open strings. Put your pinky finger on the 3rd fret of the G string. Put your middle finger on the 2nd fret of the C string. Put your ring finger on the 2nd fret of the E string. Put your index finger on the 1st fret of the A string. Strum all four strings and check each one rings cleanly.

Daug is D, F#, Bb. That is a augmented triad (root, major third, augmented fifth). Play them in any order and you still get Daug.

Restless and searching: pushes upward and refuses to settle. A dramatic transition chord. Chord quality is the interval pattern above the root. That pattern is what you hear as augmented.
