Questions about A Augmented (Aaug)

What notes are in a A Augmented (Aaug) chord?

A A Augmented (Aaug) chord contains the notes A, F, C#. It is built from the augmented formula 1 - 3 - ♯5, with A as the root.

What makes A augmented easier to hear than most augmented chords?

The open A string. Many augmented voicings mute the bass to keep the three tones clear, which leaves the chord floating with no anchor. Here the root sounds underneath the raised 5th, so you hear the tension as something happening to an A chord rather than as a chord with no home at all.
