How to play the G augmented triad on bass
The G augmented triad has 3 notes: G, B and D♯. Two major 3rds stacked. It divides the octave evenly, so the same shape repeats every four frets.
Interval steps: M3 M3 M3. Formula: 1 3 ♯5.
The root, G, is on the 3rd fret of the E string and the 10th fret of the A string. On a five-string bass it is also on the 8th fret of the low B string.

How to practise it
Start with the metronome at 60 BPM in 8th notes, ascending and descending, until you can play it without looking. Raise the tempo 5 BPM at a time with the speed builder, then switch on memory mode so the tab hides after the first loop. Earn bronze for playing it through, silver at 4 notes a second, and gold at that speed from memory.
