Formation of Augmented Chords

Formation of Augmented Chords

Why diminish is to reduce to augment is to increase.
Augmented triad had its formula as 1-3-#5
It is also called Major sharp 5 [maj#5]
Since 1-3-5 is the formula for major triad.
Augmenting the 5th note creates a maj#5 chord.

Let's try an example.
C aug triad will have its notes as C-E-G#.
