D Altered Scale notes: D Eb E# F# G# Bb C. Formula: 1 b2 #2 3 #4 b6 b7. Chords in this scale: Ddim, Ebm, E#m, F#aug, G#, Bb, Cdim.

The altered scale (super Locrian) keeps the root, 3 and b7 of a dominant chord and alters everything else: 1 b2 #2 3 #4 b6 b7, that is b9, #9, #11 and b13. Jazz players use it over a dominant chord that resolves, like G7alt to C. It is the seventh mode of melodic minor: G altered uses the notes of Ab melodic minor.
