One shape moved up 4 frets gives the next enharmonic root: C, E, and A♭ augmented are the same three notes.
About
The G augmented triad (G–B–D♯) raises the fifth by a half step, replacing the stable perfect fifth with an augmented fifth. This removes the grounding effect of the perfect fifth and gives the chord its floating, unresolved quality — every interval is a major third, making the structure symmetrical and harmonically ambiguous. It commonly appears as a passing chord between the major triad and the IV chord (G → G+ → C), or as a V+ that creates extra tension before resolving. All three tones carry weight — omitting the D♯ leaves a plain major chord, so it must be present. Augmented shapes repeat every four frets. Compared to Gdim, augmented feels more open and less tense, but equally unstable.
