Okay, our final chord type is named an altered dominant chords. If you've seen my other melodic minor tutorial you'll know that an altered dominant is a dominant chord that contains any of the following intervals in any combination, b5, #5, b9, #9.
From G examples could be G7#5b9, G7#9, G7#5#9 etc.
The scale we use over altered dominants is the superlocrian scale, also known as the altered scale. This is the 7th mode of melodic minor.
Here's the chart!
