Chord reference
Augmented triad
1 – 3 – ♯5 · example: Caug = C – E – G♯
Two stacked major thirds. It divides the octave evenly, so it has no clear resolution of its own.
Written as a formula it is 1 – 3 – ♯5: the degrees of the major scale it keeps, with any that are altered marked. On C that gives Caug = C, E, G♯.
