Baug Chord on Bass
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.
There is no open Baug on bass. The one shape below sits up the neck and is rated advanced.
Start here — Root-3-#5 Shape (7th fret)
Sits at fret 7 — tighter and brighter than the low shapes, and high enough to keep out of the way of anyone playing the open version underneath.

The shape above: Root-3-#5 Shape (7th fret).

Baug on Bass — questions people ask
What is the easiest way to play Baug on bass?
“Root-3-#5 Shape (7th fret)” — which we rate advanced — is the easiest Baug shape on bass. Sits at fret 7 — tighter and brighter than the low shapes, and high enough to keep out of the way of anyone playing the open version underneath. There is no open Baug on bass, so a barre is unavoidable; this is the least demanding one.
What notes are in the B Augmented chord?
B Augmented is B, D#, G — the 1-3-#5 interval pattern of a augmented chord. Every voicing on this page uses those notes and nothing else; they just appear in a different order and octave.
What can I play instead of Baug?
The nearest stand-ins on bass that keep the same root are B5, Bsus4, Bsus2. They keep the root and the fifth and only change what sits in the middle, so most songs still work — but check the swap against the melody, because the note you removed may be the one the tune is singing.
Can I play Baug on other instruments?
Yes. Baug is the same set of notes everywhere; only the fingering changes. This site has diagrams and audio for it on guitar, piano, ukulele, mandolin, banjo.
