Conversely, adding a double sharp to any other note not sharped or flatted in the key signature raises the note by two semitones with respect to the chromatic scale.
For instance, an augmented third such as C–E spans five semitones, exceeding a major third (C–E) by one semitone, while a diminished third such as C –E spans two semitones, falling short of a minor third (C–E ) by one semitone.
For instance, a semiditonus (3 semitones, or about 300 cents) is not half of a ditonus (4 semitones, or about 400 cents), but a ditonus shortened by one semitone.
All these intervals span four semitones.
Critical bandwidth lies between 2 and 3 semitones at high frequencies and becomes larger at lower frequencies.
Due to a different tuning technique, the twelve semitones in this scale have two slightly different sizes.
