What is dominant diminished scale?
Many authors strongly say that there are two diminished scales: The one we already showed (article “diminished scale”) and the “dominant diminished”. This dom-dim scale is nothing more than the drawing of the diminished scale that we showed but starting in the second degree instead of the first one. In other words, instead of the scale being:
- Tone – semitone – tone – semitone, etc.
Starting in the second degree, we will have:
- Semitone – tone – semitone – tone, etc.
Notice that we used exactly this second sequence in the dominant chords in the article about diminished scale, because we played the diminished scale of G# starting with G, in other words, the structure was semitone – tone – semitone – tone, etc.
Moral of the story: the dominant diminished scale is the diminished scale used in a dominant chord.
Therefore, don’t think that they are different scales; think that they are the same diminished, but used in a dominant chord (played one semitone above it). This will make your way of thinking easier.
