I've read the articles on-line...and the Levine theory book. I'm an old burn-out I guess.
I know it's a #4, comes out of MM, is a mixo with a raised 4th, etc...
Can someone briefly explain when/where I would use Lydian Dominant in "real, guitar language"...for me??
Tx, Sailor

It often sounds good to my ears on II7, IV7, and any subV, so bII7, bIII7, bV7, bVI7, bVII7
-
The way I was taught about this one was in relationship to the super locrian (alt dominant) scale, and that the scales were just TT subs of each other. The super locrian would start directly on the root, and lyd dom would start on the TT of the root.

Anytime you have a dominant chord this is static or not functional, lydian dominant is a great choice.

The most typical and traditional uses of Lydian dominant are as a bII7 and bVII7. In simplest guitar terms, built on a root(not bass!) either a fret above or two frets below the root of the target chord.
Here's the math behind it:
The very earliest usages of bVII7 chords are really as the so-called "deceptive" cadence in classical harmony, or V7 to vi. Obviously, these are just the straight diatonic major V and vi chords, but this move of a dominant up a whole step is now common. If we use it towards a I chord of Eb major, watch what happens. The notes we need for the bVII7/I (Db7) are as follows: Db, F, Ab, Cb(B). If we fill in the rest of the notes (by letter names, ex. Cb cancels C, Db cancels D) from Eb major (Eb, F, G, Ab Bb C D) we end up with the following scale: Db, Eb, F, G, Ab, Bb Cb. In this scale as it realtes to a Db7 chord, we get chord tones 1, 3, 5, -7, (Db, F, Ab, Cb,) and extensions 9, #11, 13. In other words, Lydian Dominant!!!!
As far as bII7s, the origin is slightly more modern, but also simple. The tritone of the V chord in Eb (Bb7) is D and Ab. If we try to build another Dom7 chord around this tritone, we find that we can, with Fb7(also E7, but for clarity's sake, I'll leave it as Fb). Fb7 contains Fb, Ab, Cb, and Ebb. Now, these chords bII7s are obviously closely related to the other dominant that shares the tritone, which is why we frequently call them substitute dominants: they substitute easily for the original chord. If we take that orginal chord Bb7, with it's extensions of 9 and 13 we get the notes Bb, D, F, Ab, extensions C, and G. Replacing note names with the ones from the new bII7 chord Fb7, the resulting pitch set is Fb G Ab Bb Cb Ebb, we end up with a Lydian dominant scale, minus the 6. If we go ahead and wildly add that in, taadaa, another traditional tonal usage!
To recap, Lydian Dominant harmonies work well when moving to a target rooted either a half-step below or whole step above their root.

Yes, the answers are all here. Good work, guys!
-
Right on!!!
-
Sailor, you've seen Emily Remler's video on this, right?
-
OK...going to go watch Emily Remler on this now. After all your explanations I'm still lost...and I got all "A"'s in college music theory!!
Too many different explanations...melodic minor....think up a fifth...etc...
Need to see it in action and stop reading about it....Thanks for all the great responses though.
Thanks, Sailor

Any tritone sub of a V7 is the perfect place to use it. Blues is very easily swayed with it as well. Any time I am playing a ii V I VI7, it fits beautifully over the VI7. Like it was mentioned earlier, when ever you have a non resolving, (to the I), V chord Lydian Dom is a shoe in as well. There are many applications. Just try it and see what your ear tells you. Play around with minor ii V i. Use MM based on the ii chord for the ii and V, then natural or MM down a whole step for the i. Whatever trips your trigger.
-
Emily puts her way of looking at it very simply: there are 2 kinds of dominants... (1) those that function as a V7, resolving to their implied I, and (2) those that don't. Lydian dominant sounds super hip over the second kind, dominants that don't resolve home.
Use mixo b5b13 (mode of harmonic minor) or ALT (super locrian = lyd dom a TT away from the root = mel minor up a half step) over dominants that resolve to their implied I chord.
-
Oh...thanks...all these different ways of looking at Lydian are very helpful. Lydian dominant is really just a mixo with a raised 4th too.....right??

In all actuality, I just think of it as Lydian Dominant; thinking of it as an alteration to a different mode of a different scale messes with my head! I guess whatever works for each person is probably best!
-
Well, actually Lydian b7 would be best. It is after all the 4th mode of MM.

I do agree with you however, that it is simpler, if thinking about MM modes in relation to Major/Minor modes to think of the parent scale as Ionian b3, rather than minor #6 #7.

Yes indeed. From what I understand the raising of the 7th led to a more natural resolution. The raising of the 6th in MM made it more suitable to melody and less strident. But they are a separate entity.
