The “ACE” acronym, refers specifically to the ii-V7-i cadence in E minor, and is the only Melodic Minor grouping that actually spells a recognizable word. Note, however, that each grouping contains the letter names which make up a particular minor triad, with the final letter being that of the tonic minor key. This can be a useful shortcut in determining which pertinent Melodic Minor keys work together as “ACEs”.
