Augmented and Diminished Triads

Notice that you can't avoid double sharps or double flats by writing the note on a different space or line. If you change the spelling of a chord's notes, you have also changed the chord's name. For example, if, in an augmented G sharp major chord, you rewrite the D double sharp as an E natural, the triad becomes an E augmented chord.

You can put the chord in a different position or add more of the same-named notes at other octaves without changing the name of the chord. But changing the note names or adding different-named notes, will change the name of the chord. Here is a summary of the intervals in triads in root position.
