Watch the Altered Scale (Super Locrian) online guitar lesson by Tom Dempsey from Jazz Scales Handbook

Now we'll look at another scale generated from the Jazz Melodic Minor scale that can be played over another type of dominant 7th chord. This scale is known as the altered scale. There's a lot of intrigue out there about this scale. You may have also heard of it as the "Super Locrian" mode and/or the Diminished Whole Tone scale. No matter what you call it, this scale is great for bringing out multiple tensions on a dominant seventh chord.

In this lesson, I'm going to show you a fingering of the scale in sixth position along with its corresponding arpeggio of the parent chord. This scale is an important one to learn for getting deep into the chromatic alterations on any dominant seventh chord.
