About G9#11 — inversions voicings
G9#11 answers a naming puzzle: sounds like a flat fifth, yet the natural fifth remains present. The notes are G, B, D, F, A and C#.
The symbol therefore describes an added raised fourth above , not a fifth that has been replaced. A voicing should make that distinction audible.
Also written G9(#11), G9+11 or G9♯11.
What an inversion is
How to use G9#11
G9#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 C. More voices leaning the same way is all "more tension" means here.
