What chords/scales are equivalent to Dbm7b5?

[Papageno]

Here you go, Michel. Minor 7th b5 chords occur in Solar (D-7b5, G-7b5) and in the turnaround in Footprints (F#-7b5), among others.

Scales that sound good with Dbminor7b5 chord(s)

The link given above gives a list of 61 (yes!) scales supposed to sound good with Dbm7b5.

The provide a proof ab absurdum of the point made earlier by several contributors that both the question and the (61) answers make little sense, if taken out of context!

I believe the best way for the OP to answer his own question is to learn (at least a little bit of) theory, so as to understand what works well in a given context.

If you mean that G locrian, Bb dorian and Eb mixolydian contain the same notes, this is correct.
But that does not make these 3 modes equivalent, because the hierarchy of the notes is not the same: because the chord tones of Bbm7 (the important notes of Bb dorian) do not contain the tritone, it implies a predominant harmony, whereas Eb7 (the important notes of Eb mixolydian) contain the tritone, and implies a dominant harmony. G locrian is somehow in between, and would imply a predominant harmony in F minor and a (weaker) dominant harmony in Ab major.
So it is the hierarchy of notes, as well as the harmonic context, that is important to consider.

I made a follow-up comment about Ari Roland's video. I apologize for the confusion caused by my brevity.

Those who also watch the above referenced video in post #22 will hear Roland explain, " Minor seven flat five chords are minor six chords with the six in the bass and they take the dominant seven scale for which that minor chord is the important minor" Mr. Roland gives a supporting analysis for why and how you should identify the proper dominant seven scale to play over m7b5 chords. The video is about 4 minutes long and well worth the investment of time.

I simply restated (and restated simply) Mr. Roland's thesis using the names of the modes. The Takeaway, or "boil the video down to its most simplest and basic elements" - is - "Mixolydian makes a good substitute for Locrian."

I did not state, nor mean to imply, that the modes were equivalent.

I first watched the video, listened and thought about what I heard. Then, I responded to a comment about the video. In that context, I hope I shared something that is helpful. I appreciate g-dude, a fellow dork, for having shared the video. I also appreciate Mr. Roland for making the video and sharing his knowledge.

C#m7b5 is the chord associated with the 7 th degree of the D major scale.

That was the first thing that came to my mind.

Well, I just watched this video by Ari Roland. Ari is a superb player (his arco chops are quite impressive, in particular), but to be frank, in my opinion, his explanations of Gm7b5 are really clumsy and make thinks much more complicated than they need to be.

He found a very complicated way of saying this simple thing: Gm7b5 is the ii of F minor, or the vii of Ab major, so you can play the notes of F (natural) minor or Ab major (which are of course the same). Invoking Bbm6 or Eb7 is an unnecessary detour (unless this is justified by the context).

A7 !! It's that simple. I know the A is not in there but that is what it is ;-)

Actually, his explanation by invoking Bbm6 actually helped my understanding of minor 6th chords!
