Baug Chord on Mandolin
B Augmented is B, D#, G — the 1-3-#5 pattern of a augmented chord. Here is the shape, the audio, and what usually goes wrong.
Good news: Baug has an open shape on mandolin, so you can play it without barring anything. Start there and work up the neck later.
Start here — Movable Augmented Shape (1st fret)
Open shape — open strings ring right through it and there is nothing to barre. If you only learn one, learn this one.
What beginners get wrong
Moving in and out of it
The shape above: Movable Augmented Shape (1st fret) — open position, so several strings ring unfretted.
Listening: each shape above has its own play button, and each one plays the notes that shape actually produces — not a generic triad.
