Move it up another fret and you get a Eb aug, or a B aug, or a G augmented chord. Now you have a D augmented chord, or a Bb aug chord, or a Gb aug chord. So, using 1 shape in two positions, we’ve actually made 6 augmented chords. But, because it can be named for any chord in that shape, it is also an A aug chord, or an F aug chord. Take any one of the C augmented chords shown above in Image 2, and move the whole shape up one fret. So, the augmented chord is named for any note found in that chord shape. In other words, the three notes in a C+ triad are the same as the notes in an E aug triad, which are the same as a G# aug (Ab aug) triad. They are all 4 semitones (a Major 3rd) apart. No matter which of those notes we start with, by moving 4 semitones each time, we’ll always end up with the same three notes. There are only 12 notes, so if we go another 4 semitones (a Major 3rd) from G#, we get to C again. There are 4 semitones (a Major 3rd) from E to G#. We can see that there are 4 semitones from C to E. There are 4 semitones (half tones) in a Major 3rd interval.
