How to use D9#11
D9#11 is a dominant with its tension raised, so it still points at — harder than a plain seventh does. A plain dominant has two voices a semitone from home; an altered one has four, because every altered tone is also sitting a semitone from a note of G. More voices leaning the same way is all "more tension" means here.
