Modes of Melodic Minor
Melodic Minor has the most famous rotation family outside the major scale, mostly through jazz, where each of its seven modes has its own name and its own standard use against a specific chord type. Of the seven modes, three come up most often in practice - the rest aren't in the app yet, so this page sticks to those three.
Melodic Minor (mode 1) - 1 2 ♭3 4 5 6 7. The parent scale: a minor scale with both the 6th and 7th degrees raised, closing the gap Harmonic Minor leaves open.
Lydian Dominant, also called the Overtone scale (mode 4) - 1 2 3 ♯4 5 6 ♭7. A dominant 7th chord's scale with Lydian's raised 4th instead of Mixolydian's natural one; commonly played over a dominant 7♯11 chord.
Super Locrian, also called the Altered scale (mode 7) - 1 ♭2 ♯2 3 ♭5 ♯5 ♭7. Every alterable degree of a dominant chord flattened or sharpened at once; the standard scale for an altered dominant chord, and the most commonly cited of all seven modes.
